Understanding and Management of Female Pattern Alopecia Matt Leavitt, D.O.1 ABSTRACT Female pattern hair loss is devastating to many of the 21 million U.S. women who suffer from it. It is essential to differentiate female pattern hair loss from other types of hair loss to ensure appropriate treatment. Through use of follicular units, follicular families, and follicular pairing between existing hair follicles, natural-looking results can be achieved in women. Hair transplants create the benefit of increasing density and providing options for hair styling and can be combined with medications, devices, and styling aids such as minoxidil, low-level laser therapy, and topical powder makeup, respectively. KEYWORDS: Women, female pattern hair loss, hair transplant, alopecia, follicular unit A n estimated 30 million women in the U.S., currently experience some form of hair loss, including female pattern hair loss (FPHL), and hair loss triggered by hormonal changes, medications or diseases such as thyroid conditions and anemia, chemically related alopecia, traction alopecia, and so forth. These forms can mimic each other, masking the true cause of the problem. Male pattern alopecia can be diagnosed readily. Conversely, there are many different conditions that can contribute to hair loss in women, and certain key factors may be overlooked, leading to incorrect diagnosis. A comprehensive medical history specific to the many factors in hair loss for women is essential to ensure appropriate diagnosis and possible medical testing. The correct diagnosis is essential to determine the right treatment for each individual patient. Once an accurate diagnosis has been made, there are still many elements that must be evaluated to establish an appropriate treatment plan. Treatment options range from nonmedical to medical and surgical, and potentially a combination of any of these modalities. The article will provide information on the following key factors in treating a female hair loss patient: 1 Facial Plast Surg 2008;24:414–427.

PROFILE AND PSYCHOLOGICAL IMPACT Hair loss in females may be even more devastating psychologically than it may be for males. Cultural influences and societal norms dictate, influence, and emphasize the importance of hair: it is a gauge of gender, age, socioeconomic level, and, especially for women, a personal statement. Currently, approximately 21 million women in the United States have some degree of FPHL; 414 This document was prepared for the exclusive use of valarie montalbano. Unauthorized distribution is strictly prohibited. FEMALE PATTERN ALOPECIA/LEAVITT that number is increasing rapidly as the Baby Boom population ages. Male pattern hair loss and/or total baldness is acceptable for men in society. However, this is not true for women. This is perhaps best demonstrated by the fact there are no female role models who have significant hair loss. Graying or balding in women is not perceived as ‘‘distinguished’’; the assumption is aging or disease. In 1993, one of the first studies dealing with the psychological impact reported 70% of women versus 25% of men expressed high levels of distress with their hair loss situation. Approximately half of all females seen for hair loss stated that they were dissatisfied with the initial contact they had with their physicians. This was attributable to the fact that they felt patronized and had been dismissed as too worrisome, depressed, having marital or sexual problems, or deemed ‘‘lucky’’ to have as much hair as they did. Forty-three percent of the doctors advised their patients to wait before taking any further action; of the more ‘‘aggressive’’ physicians, 10% suggested vitamins. Patients were often dismissed altogether as most of the standard tests performed for their hair loss produced results considered to be within ‘‘normal’’ ranges. Frequently, the women were prescribed treatment with antidepressants (Table 1). Twenty percent of females with hair loss seek advice from their primary care physician, 47% see a dermatologist or cosmetic surgeon, 39% see a general or family practitioner, and 1% see an obstetrician/ gynecologist. Women are skillful at camouflaging hair loss with creative styles. As a result, their loss is usually obscured because they retain the frontal hairline (85% of the patients). Therefore, it is often difficult for a physician to recognize hair loss in these patients. Females must lose more than 50% of their hair before it is visible or noticeable by others. Because it is a sensitive issue for most female patients, physicians frequently wait for their patient to raise the topic. Once this discussion occurs, it is important for the physician treat the patient’s concerns seriously and with respect. Once hair loss becomes a problem for a patient, it affects them daily. Initially, the patient may develop an elaborate routine and methods to conceal the problem. However, it is a short-term ‘‘fix,’’ and she will often withdraw from social and professional settings as the condition worsens. Many times, there is a denial factor involved; the patient believes that the hair loss is temporary and will improve once her stress factors subside. It frequently takes a great deal of time, and a deteriorating situation, for the patient to speak to a physician. After the patient has decided to seek advice from a physician, it is critical that a relationship based on trust be developed. In this consultation, the doctor must establish that he understands the patient’s concerns and what she may expect from available treatments. This discussion requires sensitivity, compassion, and time to allow the patient to express her needs and feelings with dignity. It is necessary that the staff is empathetic and conscious of the patient’s needs for privacy and understanding. ETIOLOGY OF HAIR LOSS IN WOMEN There are three primary types of hair loss, all of which are nonscarring and that account for more than 90% of all female hair loss: FPHL, telogen effluvium, and alopecia areata (Figs. 1–3). Table 2 details the incidence of all forms of female hair loss. In contrast, Table 3 lists what women believe causes their hair loss. The two greatest mimics of FPHL are telogen effluvium and diffuse alopecia areata. Before any treatment approach can be determined, it is fundamental to rule out any of the causes of telogen effluvium, diffuse alopecia areata, and the scarring forms of alopecia. Table 4 details several contributing factors that can lead to hair loss in women. The scarring alopecias can stem from diseases such as lupus erythematosus to trauma and can be more easily differentiated from the nonscarring alopecias (Table 5). Telogen effluvium is a form of nonscarring alopecia characterized by diffuse hair shedding, often with an acute onset. Hair often appears dull in these patients. Telogen effluvium is generally more visible and has a Table 1 Women’s Degrees of Concern about Hair Loss: A Survey of 2000 + Households Extremely concerned 19% Somewhat concerned 24% Slightly concerned Not at all concerned 28% 29% Figure 1 Female pattern hair loss (FPHL).

Telogen hairs increase from 10 to 30 to 50%, and 150 to 700 hairs are lost per day. Hairs are easy to comb out. Telogen effluvium lags the inciting event by approximately 3 months. In most cases, the condition corrects within 5 to 18 months; 90% of all cases correct without intervention. The best treatment is elimination or control of the cause. Telogen effluvium can originate from a wide range of issues, among which are stress, disease, drugs, and illness (Table 6). Alopecia areata affects 2% of the population. It presents as spotty, patchy, or circular areas of hair loss or can be seen as breakage/clumps of lost hair. In its diffuse form, it mimics telogen effluvium and FPHL (Fig. 3). Its most severe form is alopecia totalis (all scalp hair is lost) Serious illness, medications 17% Hereditary 14% Age 14% Stress, nerves Pregnancy, childbirth 11% 10% Note: Some women suggested more than one cause. or universalis (the total loss of hair: scalp, body, eyebrows, etc.). The condition is an immunologic disorder that can be triggered by stress. It most frequently occurs in the 20- to 30-year-old population; however, 25% of reported cases present in the 40 + age group. Regrowth of the hair usually occurs, and the condition can resolve on its own. However, recurrence can be expected. The condition is marked by an ‘‘exclamation point’’ hair when plucked. FPHL is characterized by a family history (may be difficult to pinpoint), a slow onset, slow progression, and a generally stable rate of loss. FPHL has no age predictor. It may present as early as puberty or as late as age 40 years. The peaks of onset are the third and fifth decades: 25% of women aged 35 to 40 years, and an estimated 50% of women after age 40 years, show signs Table 4 Alopecia May Be Related to Any of Several Factors Figure 3 Alopecia areata (diffuse).

Those who have earlier onset tend to develop more severe hair loss. An estimated 20% of females with FPHL have an easily identifiable family history of hair loss. FPHL is identifiable in several ways. Typically, hair loss occurs from the root of the follicle. Miniaturization, characterized by finer, smaller, slower growing, less pigmented hairs, is present. Thinning is more common than areas of noticeable hair loss and may present with a ratio of less than four terminal hairs to one miniaturized hair. The hairline and temple are mostly maintained; it is the part in the hair (center part) that is usually the first visibly noticeable area (Fig. 4). The algorithm (Fig. 5) details three categories of hair loss, their potential triggers, and possible diagnoses. CONSULTATION Hair loss is unforgiving for women. Frustration, depression, and fear are all underlying psychological issues for this patient, and the patient requires a great deal of reassurance and understanding. A female patient generally presents herself differently from her male counterpart. Aside from the emotional issues, she usually has several carefully prepared, organized, and well thought-out questions about her specific hair loss needs. Her approach is methodical, and she will expect a logical explanation for her situation.

Disorders of hair growth: diagnosis and treatment, New York: McGraw Hill; 1994). Figure 4 Example of FPHL. During the consultation and examination, it is necessary to look for a possible association between the hair loss and other conditions. These range from disease (such as lupus or a thyroid condition), reaction to certain drugs (i.e., birth control pills or b-blockers), and/or a relationship between symptoms such as an infection or stress. Unusual diets, family hair loss history, any episodes of high fever, diabetes, Hodgkin’s disease, illnesses, vitamin usage, and kidney or liver problems are questioned. The tests are crucial in diagnosing any structural hair defects, possible hair or scalp disorders, or evaluating any trauma. A thorough, detailed questionnaire is a key in obtaining essential patient history regarding hair loss (Table 7). Questions should cover a broad range of topics including family history of hair loss, illnesses, hair-care habits, medications, emotional stresses, and recent surgeries. A family history for female pattern is helpful but not essential because of the difficulty some individuals have with pinpointing a family member with hair loss. Remember slow onset and progression are common characteristics of FPHL, and the rate of loss is generally stable and from the root. EXAMINATION AND TESTS Examination most commonly shows that the patient will maintain her hairline (85%) and the temples area (90%). The majority will follow a Ludwig pattern with widening of the part. Miniaturization will be present as finer, smaller, slower growing, less pigmented hairs. Thinning is more likely than areas of complete hair loss. The ratio of terminal hairs to miniaturized hairs is less than 4 to 1. There are two hair loss charts designed specifically for evaluating female hair loss that are used in the examination. The Ludwig Classification, developed in 1977 by Dr. Erich Ludwig, defined three stages of hair This document was prepared for the exclusive use of valarie montalbano. Unauthorized distribution is strictly prohibited. 417 418 FACIAL PLASTIC SURGERY/VOLUME 24, NUMBER 4 2008 Figure 5 Appearance of hair loss and possible etiologies. loss (Fig. 6): I, II, and III (with III indicating the most advanced hair loss). Stage I reveals hair beginning to thin on the crown while the frontal hairline remains preserved. In stage II, the crown continues to thin, and the hair loss has advanced and is quite noticeable to others. Stage III is full baldness in the crown area with an increased number of shorter and thinner hairs. The frontal hairline is not preserved, and hairstyling cannot hide the loss as it is too great. Some Ludwig stage II and all Ludwig stage III patients are not candidates for surgery. The Savin Female Density scale (Fig. 7) was developed in the early 1980s. It is based on a scale of 1 through 7, with 7 representing the lowest density. This scale shows hair that is lost diffusely over the entire scalp. This is the most typical hair loss pattern for females. The examination should include hair color, texture, diameter, and damage to the hair, as well as observation for signs of erythema, scale, pustules, medications and/or drug use, and evaluation of the degree and density of hair loss. Several tests will also likely need to be ordered. Photographs should also be taken for documentation purposes. A series of photos showing many different angles and hair parts should be taken with the hair wet and dry. Although all workups should be individualized, the following lab work and tests are standard for patients with alopecia. Approximately 90% of the lab work and tests will not provide a definitive answer; however, the results will be useful for evaluation and interpretation of the underlying cause of hair loss. ‘‘Normal’’ ranges do not negate the fact that hair loss exists; it simply means that finding the reason will be more difficult. The laboratory workup should consist of routine chemistry studies, complete blood count (CBC) with differential, a urinalysis, a serologic test for syphilis, and tests for thyroid function (TSH, T4). Additional useful and helpful tests are free testosterone levels, and sex hormone binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEAS), androstenedione, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin counts. Useful, too, are serum iron, total iron-binding capacity, and ferritin levels. An abnormal endocrinopathy reading can suggest that the hair loss is the male pattern type. Tests DAILY HAIR LOSS TEST This test is performed by the patient daily for 1 week. Hairs that fall out during the day are counted, including those lost in the bathroom, on pillows, and in brushes and combs. The hairs that are presented for examination are analyzed to determine the anagen-telogen ratio. HAIR PULL TEST This test is performed to determine degree and stage of loss. A section of 8 to 10 hairs from various parts of the base of the scalp are pulled outward to the ends of the hair. One to two hairs is an acceptable number for being detached or lost. Avoid doing this test on a patient after a This document was prepared for the exclusive use of valarie montalbano. Unauthorized distribution is strictly prohibited.

The hairs are examined under a light microscope to inspect for broken hair (chemical or heat damage), dystrophic hair (seen with congenital hair abnormalities), or for intact telogen hair.

The test can also ascertain the presence of seborrhea, psoriasis, alopecia areata, and lupus. Evaluating this total medical information should result in a diagnosis for the patient (Fig. 8). As previously stated, photo documentation is an integral part of the medical record for hair loss patients and should be repeated periodically. SCALP BIOPSY A scalp biopsy is warranted in many cases using very small (4 to 5 mm) sites on the scalp. It is preferable to Treatment Options Figure 9 indicates the treatment options for FPHL.

FEMALE PATTERN ALOPECIA/LEAVITT Figure 9 FPHL treatment options. PATIENT ASSESSMENT FOR HAIR TRANSPLANTATION Traditional Ludwig stage I and II females are the most common candidates for hair transplantation (Fig. 5); however, other patterns may also exist (Table 8). Some women may present with male pattern baldness or other problems that would benefit from a surgical procedure (Table 9; Figs. 10–13). The majority of women who are candidates for surgery require increasing the density in a thinning area versus creating a hairline or transplanting a bald area. It is rare for a woman with FPHL to progress to complete baldness. A thorough examination is critical in determining if enough donor hair exists to meet the patient’s expectations both at the time of consultation and in the future. Women are generally creative with styling hair and, therefore, transplantation to localized areas may have a tremendous positive impact. It is essential to ask the patient regarding current and possible future hairstyles. Donor Area Assessment Donor hair availability and density are the case-limiting factors in determining if a woman can have surgery. The progressive diffuse loss of hair in female patients in traditional areas of donor harvesting compared with that in male patients makes the decision to determine if a female is a candidate extremely difficult. The key elements in assessing the donor area for the female patient are similar to those for men. Specifically, it is necessary to evaluate several aspects of the donor area. The individual’s inherent hair characteristics, which include color, texture, scalp to skin contrast, and level of curl, factor into the surgical design strategy for the patient. Hair that has curl will provide more coverage and look thicker with fewer grafts than will fine, straight Table 9 Female Pattern Hair Loss Hereditary changes in the hairline Traumatic alopecia Cosmetic indications Table 8 Patient Assessment for Hair Transplantation Scars Extent and pattern of loss Eyebrows/pubic region Ludwig classification (stage I, II, III) Childhood burns Bitemporal recession Cosmetically nonsatisfying operations Diffuse loss of discrete areas Frontal accentuation (‘‘Christmas tree’’ pattern) Increased awareness of the difference in male and female hairlines among patients undergoing gender reassignment This document was prepared for the exclusive use of valarie montalbano.

This woman was a Ludwig stage I patient with classic ‘‘Christmas tree’’ pattern. Figure 12 Hair transplant patient (left, before; right, after) demonstrating an example of traction alopecia. hair. Similarly, coverage can be achieved with a lesser amount of grafts if the hair color is close to the scalp color rather than hair that contrasts highly with scalp color (i.e., dark hair and light skin). However, darker hair will create the appearance of more hair volume (i.e., brown vs. gray hair or white hair). The key assessment to determine candidacy is donor density follicular unit/cm2 to recipient density follicular unit2. If the donor density is substantially better than the recipient density and sufficient donor area is available, the patient has the opportunity for excellent improvement. Another essential component is scalp elasticity. Donor density should be measured with a densitometer, whereas scalp elasticity can be measured with the Mayer-Pauls Caliper (A-Z Surgical, Hauppauge, NY). Before selecting the donor (single strip), ask if the patient ever wears her hair up in the back. Midoccipital is the most common area to take the strip; if the patient wears her hair up, it is important to take the strip superior enough to allow for this style. Figure 11 Hair transplant patient (left, before; right, after). The patient had an unusual pattern of hair loss. Notice recession in the temporal areas. Figure 13 Hair transplant patient (left, before; right, after). The patient had had radiation therapy, which destroyed the follicles. Recipient Area Examination of the recipient area should focus on the degree of miniaturization, diameter of existing hairs, pigment loss, decrease in density, and examination of the total area of miniaturization cm2. The progressive and unpredictable nature of FPHL is a huge obstacle in an accurate assessment of future hair loss. In addition, medical therapies such as minoxidil will have widely variable benefit in female patients. The other major concern in transplantation of the female patient is the propensity for postoperative shock, which is a combination of telogen effluvium and some anagen effluvium. Similar to the difficulty in predicting This document was prepared for the exclusive use of valarie montalbano. Unauthorized distribution is strictly prohibited. FEMALE PATTERN ALOPECIA/LEAVITT future hair loss, it is not possible to know which patients will be most adversely affected by this effluvium. It is therefore mandatory to discuss this risk and present a worst-case scenario with all prospective patients. However, do realize that severe telogen, and anagen, effluvium from a hair transplant does not occur in a majority of women. If it does occur, it does so as early as the immediate postoperative period and up to 3 months postoperatively. By 6 to 12 months, the hair has grown back completely. I have personally found that shock loss cannot be overemphasized because of the devastation a patient may feel when it occurs. Additional Assessment The most common complaint from the prospective FPHL patient is the ‘‘see-through’’ appearance of the frontal area of the scalp. Given the fact that donor hair is usually the greatest limiting factor, a frank discussion is required with the patient to make certain that they understand that donor hair could ultimately not be available to treat future areas of loss. Ask the patient which areas are her priorities for treatment. There are two benefits to narrowing the areas of treatment. (1) Women are accustomed to styling their hair, and placement of grafts in strategic areas may give the illusion of good overall coverage. (2) Donor conservation, more donor available for future needs: Remember, the long-term potential donor-recipient area ratio along with whether or not the patient has realistic expectations are the determining factor for hair transplant candidacy. Time and patience are required when determining the patient’s expectations. Most women will not be able to achieve dense hair in all thinning areas with transplantation. Fortunately, most women are realistic enough to understand this fact. Reasonable density in chosen areas is often possible and usually acceptable. Women who say they do not want to see any scalp are poor candidates because of the unrealistic nature of this goal. Documentation with multiple pictures (with different angles and hairstyles) is an essential tool for evaluating these patients preoperatively and for postoperative results. In summary, the hair transplant surgical concerns for transplantation of female patients are unpredictability of future loss especially in the donor zone, anagen and telogen effluvium related to a hair transplant, and diffuse thinning without baldness in which it may be difficult to transplant enough density. SURGICAL PROCEDURES Most aspects of the surgical process are the same for men and women. We will concentrate on some of the subtle differences. Preoperative Events The diagnosis of FPHL needs to be validated as previously described in this article before deciding if the patient should undergo a surgical consultation. For example, treatment of telogen effluvium is completely different and medical in nature versus the potential need for surgical treatment with FPHL patients. I recommend that female patients start on minoxidil 2% or 5% ideally 3 months before surgery. Minoxidil may have the secondary benefit of helping prevent or lessen telogen effluvium. Minoxidil will be discussed in more detail later. During the preoperative consult, we use a mirror to have a patient prioritize treatment areas and also to show the location of the donor area. Because female patients have more hair in the recipient area than do Norwood stage V and VI male patients and hair is also often longer, blood may be difficult to remove postoperatively and cause hair to become unbearably tangled. We have found that leaving conditioner in the hair is helpful in avoiding this problem. Frequent rinsing of recipient hair is also advisable. Donor Area/Suturing Anesthesia Instrumentation and anesthesia of the donor hair are the same for men and women except for the occasional use of less epinephrine in the lidocaine and tumescence in the recipient area. Similar to male patients, donor hair is selected based on density, caliber, color, and curl. If the patient states that they use a hairstyle where their hair is pulled up, a more superior occipital location is chosen. Many FPHL patients have thinning into the parietal scalp, and therefore the occipital hair is often most dense and hence most used. Parietal hair may be cautiously used as a donor location if family history and examination give comfort regarding future loss. Temple hair is not used. An incision that courses between the left and right postauricular area is most common. Density and elasticity of tissue determine the number of grafts available. Typically, we are able to harvest between 1000 and 1800 grafts in this area. A densitometer and Mayer-Pauls Caliper are used to obtain objective measurements of density and elasticity. FPHL patients are always advised that future surgery is needed. Future hair loss and patient expectations regarding density typically dictate more surgery. Location of donor area for the first surgery is planned in a way that allows the second surgical incision to ellipse the first surgical incision. Maintaining one scar allows donor area to be camouflaged easier and also enhances the ease of future surgery planning. The donor incisions are typically closed in two layers as prophylaxis against widening. The subcutaneous and subcuticular space is closed with a 4-0 monofilament absorbable suture and a continuous horizontal mattress stitch below the papilla. This successfully closes the dead space, removes all tension from the skin, and This document was prepared for the exclusive use of valarie montalbano.

It is sutured with very superficial skin bites that are placed very close together. In the author’s 20 + years of performing surgery on female patients, I have observed that the scalp epidermis and dermis is typically thinner and the subcutaneous fat is less fibrous. The practical application of this observation is the increased importance of using subcutaneous/subcuticular sutures in addition to suturing skin. Recipient Area/Graft Preparation Characteristics of the type of female pattern patient dictates the type of graft used. Female patients typically do not have areas of complete loss but instead are thinning, and most female patients have maintenance of the hairline and temples. The goal is to increase density. Because donor hair is usually not sufficient to keep up with all areas of present and future loss, it is critical to transplant those areas that will allow the patient to get the best coverage in the most visible areas. Priority areas are often just behind the hairline and in the part (versus in the central vertex area). Net increase in density is equal to the hairs gained less hairs lost. Therefore, magnification is critical when making recipient sites to avoid damage to existing hair. The sites must be made at exactly the same angle and direction to prevent injury to existing hair. The angle is generally less acute than what is typically performed in hairlines or in patients with complete loss. It is also critical to maintain hemostasis for clear visualization of existing hair. Typically 1-, 2-, 3-, and 4-hair follicular units are placed in incisions of 0.7 mm to 1.3 mm. Follicular pairing, a technique that places more than one Figure 14 Two whole follicular units. Figure 15 Placement of follicular pairing. follicular unit in the same site, may be used to increase density. For example, a one-hair follicular unit may be paired with a three-hair follicular unit in the same site. There is little risk of an unnatural result because this technique is not used in the hairline and there is usually plenty of surrounding hair (Figs. 14 and 15). Follicular families are similarly used to create more density, for example, if a two-hair follicular unit is adjacent to a one-hair follicular unit, the graft can be prepared as a graft with three hairs. In the author’s practice, I typically transplant a density of 20 to 35 follicular units per cm2 in female patients. I have found that dense-packed cases have been more predisposed to significant telogen effluvium; of course, exceptions do exist (Fig. 16). Figure 16 Follicular unit and follicular family.

FEMALE PATTERN ALOPECIA/LEAVITT Figure 17 Hair transplant patient (right, before; left, after) demonstrating an example of FPHL. Postoperative telogen and anagen effluvium are the greatest concern. Preoperative treatment with minoxidil 2% or 5% along with meticulous surgical technique and avoiding dense packing have been most helpful in our practice. In addition, we are much more judicious in the amount and frequency of tumescence with epinephrine. An effort is made to use a tumescent solution containing epinephrine only one time in the recipient area; because of this, close coordination of the timing of these injections with placement of grafts is necessary. Postoperative Care Female patients are brought back for hair washes on postoperative day 1. This ensures that all grafts are sitting in the correct position and that surrounding hair is clean and that the donor is also free of blood. It is essential to make sure patients restart their minoxidil treatment within 1 week after surgery. Low-level laser therapy (LLLT) is also recommended. Many studies extol the benefits of LLLT for wound-healing and pain management. It is the author’s experience that it also helps postoperatively in hair transplants. Specifically, I have seen a decrease in the amount of crusts, erythema, and edema. Graftcyte, (Procyte/Photomedex, Redmond, WA) a copper peptide wound-healing solution, is also recommended to reduce the postoperative sequelae of crusting and erythema. Styling may be more difficult postoperatively, and subsequent frustration and anxiety are not uncommon for female patients. Slightly changing the part is helpful in camouflaging. A topical camouflaging agent such as Topik powder (Spencer Forest, Westport, CT) is extremely useful and recommended for those patients who still have difficulty hiding their surgery or hair loss. Topik should not be applied immediately Figure 18 Female hair transplant patient (right, before; left, after) demonstrating an example of male pattern hair loss.

Unauthorized distribution is strictly prohibited. 425 426 FACIAL PLASTIC SURGERY/VOLUME 24, NUMBER 4 2008 postoperatively; 5 days is our earliest recommended time for application. The anxiety of postoperative telogen effluvium is significant for female patients, even when they know it may occur and that it will resolve. Follow-up appointments at 2 weeks, 3 months, 6 months, and 9 months are scheduled to provide contact with patients where they may be examined and reassured that they are doing fine. A video microscope that provides 50 magnification and projects the image of the scalp examination on a television screen is very helpful and reassuring to patients. They are able to clearly see the new grafts that are coming in and also the improvement in density. They are also able to visualize improvement in the pigment and caliber of new hairs as opposed to miniaturized hairs (Figs. 17 and 18). of telogen hair to anagen, and prolongation of the anagen phase. Side effects were minor, consisting primarily of contact or irritant dermatitis in 6% of patients with 5% minoxidil topical solution and in 2% of patients with 2% topical minoxidil. Facial hypertrichosis occurred in 3 to 5% of women using the 2% minoxidil solution. The 5% minoxidil group tends to have a higher incidence of hypertrichosis. Minoxidil 2% or 5% is recommended at the time of the initial hair loss consultation. It is recommended in our practice that application be stopped 5 days prior to surgery and restarted 2 to 7 days after surgery, or as soon as tolerated. In addition to the benefits mentioned above, use of minoxidil appears to delay the shedding seen after hair transplant surgery and may shorten the period for grafted hairs to regrow. Some potential suggestions for application: OTHER TREATMENT OPTIONS As recently as 20 years ago, there was virtually no medical path on which women with FPHL could venture. It frequently remained untreated by physicians because they had few, if any, solutions for this specific type of hair loss. The factors that produce FPHL are not completely understood, and it is clear that more than dihydrotestosterone (DHT) is involved. There are thousands of nonmedical ‘‘cures’’: lotions, potions, herbs, home remedies, and concoctions for hair loss, some of which defy all believability. If any of these were truly effective, reproducible medical studies would validate their claims. Currently, there is only one FDA-approved medication for FPHL or thinning hair in women that can claim regrowth. In 1988, minoxidil 2% was approved for treatment of male pattern hair loss after studies demonstrated statistically significant improvement in hair counts and an excellent safety profile. In 1992, 2% minoxidil was approved for use in women. In 1996, 2% minoxidil was approved as an over-the-counter (OTC) medication for men and women with pattern hair loss. In 1997, the FDA approved 5% minoxidil as an OTC medication without initially approving the formulation as a prescription product. A more cosmetically elegant form of minoxidil, Rogaine Foam (Johnson & Johnson, Morris Plains, NJ), was recently released in 2007. Patients who have switched to the foam have been more compliant in both consistency and duration of use. Minoxidil is considered to be a nonspecific biologic response modifier with an unknown mechanism of action in hair growth. It appears to act directly on viable, suboptimally functional follicles as a potassium channel agonist. In women, minoxidil 2% solution increased hair counts by 29% and hair weights by 42% compared with –2.6% and 1.9% for control over a 32-week test period. Benefits of treatment include enlargement of miniaturized follicles (increase in diameter), conversion Remember foam Apply Rogaine Topical Solution (Johnson & Johnson, Morris Plains, NJ) twice daily. Towel dry or blow dry hair before application. Apply Rogaine Topical Solution directly onto scalp. Wash hands after application. Apply 5 minutes before using styling aids. Do not shampoo or swim for 4 hours after application. Let solution dry before going to bed. The other group of medications that helps women with hereditary hair loss is called antiandrogens. The goal of antiandrogens is the deliberate interference with androgens (male hormones) in the body to help alter the course of hair loss. The failure of finasteride to provide clinical benefit to most women with FPHL reinforces the belief that FPHL is not solely DHT dependent. Women who have hair loss secondary to excess androgens may benefit. It is important to emphasize to female patients that finasteride is prohibited in any female who may potentially become pregnant because it might cause abnormalities of the external genitalia of a male fetus. In some cases, doctors do prescribe the drug off-label for postmenopausal women in the treatment of FPHL. Cyproterone acetate is another potent antiandrogen. It works by competing with DHT for androgen receptor binding. It has been approved in Europe and has been shown to benefit women with FPHL, women with hair loss and high ferritin levels or clinical evidence of hyperandrogenism, including acne, hirsutism, menstrual irregularities, and a high body mass index. Potential side effects include menstrual irregularities, weight gain, breast tenderness, loss of libido, and the potential feminization of a male fetus. The latter side effect requires concomitant use of oral contraceptives. Birth control pills that contain small amounts of cyproterone acetate are Diane and Dianette (Bayer AG, Pittsburgh, PA), (but are not available in the United States).

FEMALE PATTERN ALOPECIA/LEAVITT Spironolactone is approved in the United States as a medication for high blood pressure. As an off-label drug, it is commonly used to treat alopecia and hirsutism in females. It is believed to work in arresting hair loss by interfering with testosterone synthesis or its production and by suppressing the 5a reductase activity. It also increases peripheral conversion of testosterone to estradiol (female estrogens are believed to extend the anagen phase and provide protection against hair loss). It competes with DHT for the androgen receptor and may decrease androgen production of male hormones. In a few small clinical trials, hair growth was not seen, but the trials did show that spironolactone might slow down hair loss. If doses above 100 mg a day are taken, uterine bleeding can be a side effect, and there may be a possible risk of developing breast cancer. Spironolactone may also cause abnormal fetal development, so a form of birth control is also recommended when taking this drug. Although not approved by the FDA specifically for use as an antiandrogen, it is widely administered for this purpose and must be carefully supervised. Another option for FPHL patients is LLLT, which has been used for numerous medical conditions for the past 40 years. More recently, this decade has seen a focus on LLLT and hair loss, specifically regarding its applications for hair growth/maintenance. There are two types of devices, hood and hand-held, which deliver energy to the scalp. This energy is absorbed by the cells to stimulate them. Several studies have shown the effectiveness of these lasers in wound healing, pain management, and reduction of inflammation; currently there are several studies under way for hair growth and maintenance. The first FDA-approved device for hair growth in men was the Hairmax Lasercomb (Hairmax LaserComb Manufacturer, Boca Raton, FL), (hand-held) in 2007. The author’s practice has found this therapy to be a valuable tool for some female hair loss patients. We have recently begun to treat female patients with the device. It has also been effective in many female hair transplant patients in terms of more rapid wound healing and decreased erythema. It appears to have a beneficial effect on decreasing telogen effluvium after transplantation in some hair transplant patients. Currently, we have been receiving feedback from patients regarding an increased manageability and thicker ‘‘feel’’ to their hair, as well as a deepening of their hair color. The Hairmax Lasercomb has an application before the FDA for clearance for hair growth and safety in females. CONCLUSION FPHL is devastating to many of the 21 million U.S. women who suffer from it. It is essential to differentiate FPHL from other types of hair loss to ensure appropriate treatment. Through use of follicular units, follicular families, and follicular pairing between existing hair follicles, natural-looking results can be achieved in women. Hair transplants create the benefit of increasing density and providing options for hairstyling and can be combined with medications, devices, and styling aids such as minoxidil, LLLT, and topical powder makeup, respectively. Although hair restoration surgery is time consuming, it is extremely gratifying. As a physician, I have experienced great joy in seeing what a difference it can make in a woman’s life.
