Another cause of eyebrow hair loss is genetic predisposition. Many patients naturally have thinner eyebrows that run in their family. This is one of the biggest reasons patients seek our services. Medical conditions such as hypothyroidism, eczema, and alopecia areata (spot baldness) can also lead to brow hair falling out. It’s important to determine the cause of your condition to find an effective treatment.
Eyebrow hair loss is an unfortunate happening to many people since eyebrows help in giving your face a frame and charming looks. Imagine how you would look like without prominent features on your face such as eyebrows. You can see how funny each of the celebrities with  on someone’s face. We are not talking about people who are born with naturally few eyebrows or . If you are suffering from other common skin disease such as seborrhea, contact dermatitis, psoriasis among others, expect to suffer from brow hair losses.

The hormone imbalance known as hypothyroidism is a common cause of abnormal eyebrow thinning, especially in women; roughly 27 million Americans suffer from thyroid disease, and about 80 percent of them are women. Thinning eyebrows appear as a symptom of both hypothyroidism (underactive thyroid production) and hyperthyroidism (overactive thyroid production), alongside issues such as excessive fatigue, difficulty losing weight and constantly feeling cold. If your brows appear particularly thin around the edges, visit your doctor for a thyroid screening, which should include thorough blood work. With prescription medication, your eyebrows should fill back in over the ensuing months.

When a woman is experiencing hair loss and has PCOS, spironolactone is often prescribed and it can be helpful but it’s important as well to address all these other issues when it comes to PCOS related hair loss. It’s also important to know that there is only a mild correlation of elevated testosterone on a blood test and hair loss. This is likely due to the hypersensitivity of the follicle to androgens in PCOS. Basically we get an exaggerated reaction from a smaller amount of testosterone.


While these factors contribute to hair loss for any woman, it’s particularly dicey for those of us with PCOS because when the follicle is exposed to our elevated androgens such as DHT (di-hydro testosterone, an active metabolite of testosterone) it gets damaged. Whenever a cell is damaged it generates oxidative stress which further alters the androgen receptor in the follicle perpetuating the issue.
Reproductive hormone changes can also play a part, and dermatologists believe the same factors that cause hair loss from the scalp, a common problem for women as they age, may contribute to thinning brows. Nanette Santoro, M.D., ob/gyn and professor of reproductive endocrinology at the University of Colorado at Denver, says, “Abrupt hormone changes can cause sudden hair loss (telogen effluvium) that recovers over about six months' time. It happens postpartum to many women and can happen at menopause.”
A new entity variously called as trichodysplasia spinulosa,[128] trichodysplasia of immunosuppression,[129] and cyclosporine-induced folliculodystrophy[130] has been described in immunocompromised patients, usually organ transplant recipients on immunosuppression. It involves the development of alopecia predominantly of the face with indurated spinous papules. There is a profound loss of eyebrows[131] and sometimes eyelashes. The histopathologic picture is that of abnormal follicles with hyperkeratotic infundibula and absence of normal hair shafts. The inner root sheath epithelium showed proliferation in the cells and dystrophic trichohyaline granules. Electron microscopy of skin showed presence of intracellular viral particles.[132] This entity has lately been reported in immunosuppressive states in patients without organ transplantation such as leukemias and lymphoma.[133–136] van der Meijden et al. described the discovery of a new polyoma virus in a patient with trichodysplasia spinulosa.[131] Histopathological examination can reveal the diagnosis. A recent simple pull-test wherein the spicules can be plucked and examined under the microscope for inner root sheath keratinization has been described.[136] Some successful treatments described are cessation of cyclosporine therapy[130] and oral valganciclovir[137,138] and topical cidofovir.[131]
The real culprit appears to be dihydrotestosterone (DHT), a more potent form of testosterone. DHT is made from testosterone by a specific enzyme in the body, and while both testosterone and DHT are known to have a weakening effect on hair follicles, there appears to be something unique about the conversion process of testosterone to DHT that relates to thinning hair. This is why some drugs that are marketed for hair loss block the conversion of testosterone to DHT. (It’s important to note, however, that these drugs tend to be less effective in women than men, and that one of them—finasteride—is only approved for hormonal hair loss in men, not women. What’s more, the drug has been associated with increased risk of sexual side effects, depression, nausea, hot flashes, and increased estrogen levels—and too much estrogen is its own risk factor for thinning hair; more on that below.)
Hair loss or baldness is a genetic trait, but unlike what you may have been told, it’s not necessarily passed down from your maternal grandfather. Medical science has come to learn that hair loss genes are actually passed down from both sides of the family, and they affect hair loss in both men and women. Hair loss genes may also skip generations and are utterly random in terms of which siblings (male or female) they will affect. The cause of hair loss for one family member may differ from that of another.
Flutamide is an oral anti-androgen that acts by competitively inhibiting the uptake of androgen and its nuclear binding in target tissues (Varothai and Bergfeld, 2014; Watson Pharma, 2011). It has been shown to be effective for the treatment of FPHL in hyperandrogenic women at a dose of 250 mg per day. One case report showed that treatment with flutamide was effective in a patient who had already failed to improve with spironolactone and minoxidil (Carmina and Lobo, 2003, Yazdabadi and Sinclair, 2011). After 2 years of therapy, 80% of patients were satisfied or highly satisfied with their treatment effect regardless whether they were taking concomitant oral contraceptives (Paradisi et al., 2011). Flutamide can cause hepatotoxicity and serial monitoring of liver function tests is recommended during treatment (Watson Pharma, 2011) even though data from one study on the safety and tolerability of flutamide showed that patient transaminase values returned to normal after treatment was discontinued and that levels did not rise while patients were treated with doses of 62.5 mg or 125 mg. Flutamide is classified as pregnancy category D.

It is perfectly normal for people to shed 50 to 100 hairs per day. This generally doesn't cause noticeable thinning of scalp hair because new hair is growing in at the same time that hair is shedding. However, hair loss occurs when this hair growth cycle and shedding is disrupted or when the hair follicle becomes destroyed and replaced with scar tissue. Female pattern hair loss (androgenetic alopecia) is the most common form of hair loss in women. This occurs gradually and is caused by genetics (from either side of the family), age, and the action of a specific male hormone, dihydrotestosterone (DHT). This hormone is found in lesser amounts in women and it preys on the hair follicles, preventing them from receiving vital nutrients for proper hair follicle growth, leading to the hairs shrinking, and resulting in a shorter lifespan. Interestingly, DHT does not need to be elevated to generate hair loss. Estrogen, when lowered as commonly seen in menopause, creates a change in the ratio of male to female hormones, giving an edge to these male hormones. Compounded with the sensitivity of DHT to the hair follicles, heredity can affect the age at which a woman begins to lose her hair, as well as the rate of hair loss and the extent of baldness. 


There is also a different in the form of 5AR enzyme (5 alpha reductase) found on the facial hair follicles vs. the scalp hair follicles. This enzyme converts testosterone into that more problematic DHT. Type I DHT is found in sebaceous glands on the face and genital area whereas Type II is found in hair follicles of the scalp. Type II DHT is typically more of a problem in men, but Type II is increased in disorders with high testosterone like PCOS.
“…a beauty editor told me she had been using Viviscal... Since beauty editors see truckloads of products every week, I was immediately convinced when she said it worked – so I bought it myself. I started taking it twice a day for the first six months and saw dramatic results within three to four months. My hair was less thinned out …and it was also less brittle. I’ve gone to the same hairdresser since I was 19, and he was the first to comment on how full and strong my hair looked…”

The dermatologist also will carefully look at your scalp and hair. During an exam, the dermatologist may pull on your hair. Sometimes a dermatologist needs to pull out a hair to get the necessary evidence. And sometimes a dermatologist needs to look at the hair on the rest of your body to see whether there is too little or too much hair in other areas.


Eyebrows frame your face and play an important role in your facial appearance and expressions. If the hair in your eyebrows starts falling out, you are sure to see a difference in your appearance, which you may want to rectify. Many conditions can cause eyebrow loss.[1] However, you can usually take steps to reverse the effects, such as eating a healthy diet and adjusting your beauty routine or lifestyle to account for the natural aging process.


Women using oestrogen supplementation or taking birth control pills will also experience hair loss when they cease supplying their body with extra oestrogen. These forms of hair loss may be temporary but this, however, does not mean that there is no link between oestrogen and permanent hair loss. Scientists have noted up to 30 hormones that could play a role in female pattern hair loss – the genetic kind of hair loss – and oestrogen, whilst poorly explored, may be one of them. It’s alright if the excess hairs are the ones that are lost but when normal hair falls out, there’s a problem.
Medicines may also help slow or prevent the development of common baldness. One medicine, minoxidil (brand name: Rogaine), is available without a prescription. It is applied to the scalp. Both men and women can use it. Another medicine, finasteride (brand name: Propecia) is available with a prescription. It comes in pills and is only for men. It may take up to 6 months before you can tell if one of these medicines is working.
Madarosis is the hallmark of lepromatous leprosy. It was reported in 76% of patients with multibacillary leprosy.[76] Bilateral symmetric cicatricial madarosis occurs in lepromatous leprosy due to histiocytic infiltration of hair follicles[77,78] [Figure 4]. It occurs in multibacillary leprosy after at least 5 to 10 years of untreated disease.[79] Loss or atrophy of the eyelashes may follow. Madarosis adds to the cosmetic disfigurement caused by leprosy. Absence of madarosis is a good prognostic sign in long-standing cases.[80] Unilateral madarosis may occur in tuberculoid leprosy due to the facial patch in the eyebrow region. In tuberculoid leprosy, madarosis occurs due to granulomatous infiltration of hair follicles leading to their destruction.
If you have a case of estrogen dominance, you can help bring your levels down to normal by keeping your gut healthy and avoiding refined carbohydrates like white bread and white rice. Also, avoid eating any meat that has been treated with hormones. If you have low levels of estrogen, solutions include minimizing your stress, practicing a healthy diet, and exercising regularly.
The hormonal process of testosterone converting to DHT, which then harms hair follicles, happens in both men and women. Under normal conditions, women have a minute fraction of the level of testosterone that men have, but even a lower level can cause DHT- triggered hair loss in women. And certainly when those levels rise, DHT is even more of a problem. Those levels can rise and still be within what doctors consider "normal" on a blood test, even though they are high enough to cause a problem. The levels may not rise at all and still be a problem if you have the kind of body chemistry that is overly sensitive to even its regular levels of chemicals, including hormones.
Take extra care in looking after your hair. Use a gentle, nourishing shampoo (we love Bumble and Bumble Gentle Shampoo) to promote good condition and prevent breakage. Try using a silk or satin pillowcase. Avoid harsh styling products and techniques that apply heat to the hair (blow drying, curling irons etc) as these can cause more damage to fragile hair.
Over Plucking: I know the temptation of tweezing your eyebrows when you don’t want to endure the pain of threading. But when you pluck your eyebrow hair, you’re pulling it out from the follicle and essentially damaging it. And repeatedly plucking your hair eyebrow hair can permanently damage your follicles over time and prevent them from producing new hair.
Topic prostaglandin analogues are used for the treatment of glaucoma. Uniocular increase in length, thickness, and pigmentation of the lashes were described by Johnstone in 1997 by patients using latanoprost in one eye.[184] There are reports of a response of alopecia of eyelashes to cutaneously administered latanoprost,[185,186] though others report limited success.[187] Eyelash growth has also been reported following bimatoprost 0.03% topically to the base of the eyelashes in healthy individuals[188–190] and in individuals with alopecia areata.[191] Bimatoprost ophthalmic solution 0.03% is the only Food and drug administration (FDA)-approved product to safely and effectively enhance the growth of a patient's own eyelashes.[192,193]
A little farther up the follicle is the mysterious feature called the bulge. That's where follicle stem cells live. When they get the right set of chemical signals, these self-renewing cells divide. They don't divide like normal cells, in which both halves become new cells that keep splitting and developing. Only one half of the follicle stem cell does that. The other half becomes a new stem cell, and stays put for future regeneration.
The most common type of hair loss seen in women is androgenetic alopecia, also known as female pattern alopecia or baldness. This is seen as hair thinning predominantly over the top and sides of the head. It affects approximately one-third of all susceptible women, but is most commonly seen after menopause, although it may begin as early as puberty. Normal hair fall is approximately 100-125 hairs per day. Fortunately, these hairs are replaced. True hair loss occurs when lost hairs are not regrown or when the daily hair shed exceeds 125 hairs. Genetically, hair loss can come from either parents side of the family.
Also new is the HairMax Laser Comb. It's a red light therapy hairbrush-like device that increases circulation and the biological march that makes hair. It's only approved in men (though some women are using it) and in my experience, is not as good as minoxidil. But in one study, 45% of users reported improvement after eight weeks, and 90% saw improvement after 16 weeks.
While these factors contribute to hair loss for any woman, it’s particularly dicey for those of us with PCOS because when the follicle is exposed to our elevated androgens such as DHT (di-hydro testosterone, an active metabolite of testosterone) it gets damaged. Whenever a cell is damaged it generates oxidative stress which further alters the androgen receptor in the follicle perpetuating the issue.
