Tames and Goldenring described a case of bilateral loss of eyebrows and eyelashes in a patient with AIDS-related complex who had smoked crack cocaine. This has been attributed to hot vapors during the process of smoking, and which therefore caused singeing of the brows and lashes. There was a complete reversal once the patient abstained from cocaine.[93]
Optimal levels of estrogen help to grow full thick hair, while low estrogen levels lead to thin and stalled hair growth, which eventually leads to hair loss. Through the years, a women will go through various cycles of highs and lows in estrogen levels. Puberty is typically associated with high estrogen levels as a woman starts to cycle through menstruation. Pregnancy typically increases hormone production, but once the baby has been delivered the mother can experience a drop in estrogen levels, which can result in thinning and loss of hair. Typically, this corrects itself as the woman's body heals and hormonal regulation returns to normal.  The largest decline in estrogen levels is during menopause. Estrogen is secreted through the ovaries and adrenal glands. When a woman hits menopause, the ovaries’ estrogen production is significantly diminished, which puts an excess burden on the adrenals to produce it. However, as the adrenals are typically overburdened due to stress, symptoms of menopauses like hair loss and hot flashes occur prematurely and excessively for some. Nourishing the body and balancing stress levels will support gentle and graceful transitions.

Skin infections can cause hair loss at the affected area. One of the more common causes is a fungal infection of the skin, also sometimes referred to as a ringworm. Eyebrow fungus is more likely to be related to a scalp fungus (tinea capitis) and both areas are often affected at the same time. A bacterial infection is another possible cause. Folliculitis for example is a condition where the hair follicle becomes infected usually with bacteria like Staphylococcus aureus. Eventually this can lead to loss of the hair in the infected follicle.
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.
Sinclair Scale: The 5-point Sinclair Scale is a modified visual grading scale. Grade 1 is normal. This pattern is found in all girls prior to puberty, but in only half of women age 80 or over. Grade 2 shows a widening of the central part. Grade 3 shows a widening of the central part and thinning of the hair on either side of the central part. Grade 4 reveals the emergence of diffuse hair loss over the top of the scalp. Grade 5 indicates advanced hair loss. This grade is uncommon, occurring in less than 1% of women.
Toxic alopecia occurs when there is a disruption of hair growth in the anagen phase. This usually occurs following chemotherapy and radiotherapy.[94] Radiotherapy for various types of ocular tumors, eyelid and choroidal tumors have been reported to produce madarosis.[95–97] Hair loss due to radiation is usually reversible, but may be permanent when the dose of radiation is in the range of 50 to 60 Gy.[94]

Dozens of other causes of eyebrow loss are also possible including a variety of infectious, autoimmune and inflammatory conditions. Consultation with a dermatologist or hair transplant surgeon is recommended. I strongly advise consulting a dermatologist before proceeding to hair transplantation for women over 40 with new onset eyebrow hair loss after age 40.

Despite the name androgenetic alopecia, the exact role of hormones is uncertain. It is well known that androgens affect the growth of the scalp and body hair and even Hippocrates observed 2,400 years ago that eunuchs did not experience baldness (Yip et al., 2011). However, hyperandrogenism cannot be the only pathophysiologic mechanism for FPHL because the majority of women with FPHL neither have abnormal androgen levels nor do they demonstrate signs or symptoms of androgen excess (Atanaskova Mesinkovska and Bergfeld, 2013, Schmidt and Shinkai, 2015, Yip et al., 2011). Furthermore, cases have been reported in which FPHL developed in patients with complete androgen insensitivity syndrome or hypopituitarism with no detectable androgen levels (Cousen and Messenger, 2010, Orme et al., 1999).
It’s important to keep your stress levels in check to prevent a hormonal imbalance. Reduced estrogen production can affect your brain chemistry and cause mood swings, anxiety, and depression. However, doing yoga and other breathing relaxation methods are especially effective in fighting menopausal symptoms. Exercising regularly can also help reduce stress.

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.


Other important vitamins for eyebrow hair growth to consider include vitamin B complex especially vitamin B-12, B-7 (biotin), can ensure healthy hair and skin. In addition, vitamin D can help in hair growth by creating new pore and thus a possibility of more hair (see more on Stem Cells Translational Medicine. Finally ensure you have zinc, enough protein, and omega 3 fatty acids.
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.
Growth on Eyebrows – Some common growths on brow aresa such as warts or any unusual growth could hamper eyebrow growth. Skin growth cause a thick barrier that is shell like and it will make it impossible for eyebrows to penetrate them thus you will not have regrowth. Some of the common growths include moles, hemangiomas, seborrheic keratosis among many others.
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.

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.
When men have hereditary hair loss, they often get a receding hairline. Many men see bald patches, especially on the top of the head. Women, on the other hand, tend to keep their hairline. They see noticeably thinning hair. The first sign of hair loss for many women is a widening part. In rare cases, men see noticeably thinning hair. And in rare cases, women can see a receding hairline or bald patches. The reasons for this are unknown.

After giving birth, reaching menopause years or experiencing other hormonal imbalances, it’s not uncommon for women to start losing hair. And while hair loss is a normal process (the American Academy of Dermatology estimates the average person sheds about 50-100 hairs a day), it’s also something that can be remedied by addressing underlying health and hormonal problems.
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.
Madarosis is a terminology that refers to loss of eyebrows or eyelashes. This clinical sign occurs in various diseases ranging from local dermatological disorders to complex systemic diseases. Madarosis can be scarring or non-scarring depending upon the etiology. Appropriate diagnosis is essential for management. Follicular unit transplantation has been found to be a useful method of treating scarring madarosis and the procedure relevant to eyebrow and eyelash reconstruction has been discussed. A useful clinical approach to madarosis has also been included for bedside diagnosis. The literature search was conducted with Pubmed, Medline, and Google scholar using the keywords madarosis, eyebrow loss, and eyelash loss for articles from 1960 to September 2011. Relevant material was also searched in textbooks and used wherever appropriate.
