Telogen effluvium, a type of scalp hair loss characterized by hair shedding, may affect the eyebrows as well. It can be caused by any emotional or physiological stress, for example acute or chronic illnesses, hormonal changes, nutritional deficiencies, and medications that alter the normal hair cycle and cause the hair the enter the telogen phase prematurely.
Another reason that you have thinning eyebrows might be low thyroid (which is called hypothyroidism. The thyroid gland controls the rate of use of energy sources, protein synthesis by producing thyroid hormones. I the thyroid gland does not produce enough hormones, you might feel tired, freeze in the cold, gain weight or lose your hair. The most common cause of hypothyroidism is iodine deficiency.
Also called “chastetree,” Vitex is an herb which is typically prescribed to treat estrogen dominance. It seems to be recommended as a remedy for especially low levels of estrogen as well however, and does seem to have a general balancing effect on the overall ratio of estrogen to progesterone. Vitex’s balancing effect is thought to result from the stimulation of dopamine production.
If you’re experiencing hair loss, topical treatments like minoxidil (Rogaine) and others tend to only be partially effective, if they are effective at all; they don’t address the root causes of hair loss; they target androgenic alopecia (which only accounts for some cases of hair loss); and they come with a host of unpleasant side effects—side effects that can worsen the aesthetic problem you were hoping to fix. Rogaine can cause hair to grow in different colors and textures than the surrounding hair and can cause unwanted hair to grow on your cheeks and forehead.
Hansen’s disease – Hansen’s disease, popularly known as leprosy could cause loss of eyebrows. This condition is cause by infection of a bacterial known as mycobacterium leprae and if it affects your eyebrows region, you expect to lose some eyebrows i.e. if it affects your eyebrow skin region, a place it often afflicts, you could suffer from permanent eyebrow hair loss as ‘Tulay Cakiner-Egilmez, Ph.D., R.N’ reports in ‘Journal of the American Society of Ophthalmic Registered Nurses’. This and other infections that can cause loss of eyebrows.
This plant is native to North America and has been used for centuries by indigenous people to treat menstrual and menopausal disorders. While modern research results are mixed, some studies do indicate that black cohosh can be effective as a treatment in menopause. While the research focuses on hot flashes and other symptoms of menopause that get more attention than hair loss, it follows that black cohosh could also help to improve hair growth when estrogen levels decline.
Cyproterone acetate works in several ways. It not only competitively blocks DHT from binding to its receptors at target tissue (Gilman et al., 1990), but it is also a progestogen that lowers testosterone levels by decreasing the release of luteinizing and follicle-stimulating hormones through pituitary-mediated supression (Gilman et al., 1990, Varothai and Bergfeld, 2014). An open intervention study of 80 women who received treatment with spironolactone (200 mg daily) or cyproterone acetate (50 mg daily or 100 mg for 10 days per month if premenopausal) showed that three of four patients demonstrated an improvement or stabilization of their disease with no difference of effect between the therapies received (Sinclair et al., 2005).
A number of skin and hair disorders can lead to eyebrow hair loss and sometimes it may be linked to systemic diseases like lupus. Specific skin and hair disorders that are most likely to lead to eyebrow thinning and hair loss have been discussed below but other conditions like psoriasis may also be involved if it occurs on the eyebrow or forehead. Eyebrow hair loss may occur in people on chemotherapy (cancer medication) and with radiation therapy to the head.
This is most commonly found in women wearing ponytails, tight braids or any hairstyles that typically pull on hair with excessive force. In addition, rigorous brushing, heat styling and rough scalp massage can damage the cuticle, the hard outer casing of the hair. This causes individual strands to become weak and break off, reducing overall hair volume.
Male pattern hair loss has been established as androgen-dependent because it is associated with changes in the androgen receptor and responds to antiandrogen therapy (Ellis et al., 2002). With FPHL, genes that encode aromatase, which converts testosterone to estradiol, are also implicated (Yazdabadi et al., 2008, Yip et al., 2009). The process of androgen biosynthesis is depicted in Figure 1.
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.
Surgeries, severe illnesses and emotional stress can cause hair loss. The body simply shuts down production of hair during periods of stress since it is not necessary for survival and instead devotes its energies toward repairing vital body structures. In many cases there is a three month delay between the actual event and the onset of hair loss. Furthermore, there may be another three month delay prior to the return of noticeable hair regrowth. This then means that the total hair loss and regrowth cycle can last 6 months or possibly longer when induced by physical or emotional stress. There are some health conditions which may go undetected that can contribute to hair loss. These include anemia or low blood count and thyroid abnormalities. Both of these conditions can be detected by a simple, inexpensive blood test.

Male pattern baldness is connected to the male sex hormone androgen. So naturally, reducing your stress levels will also reduce the risk of suffering from the different symptoms that stress cause. You can reduce stress by practicing mindfulness and yoga. You can also cut down on work and make sure to get enough sleep. Minimize your exposure to negative people or experiences. Spending time in nature and exercising also contribute greatly to your mental health.

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.
No one wants to lose their hair, but for women it is especially traumatic. Men can shave their heads and look hip, even sexy. Most women don’t want to be bald. Though it is more common — and visible — in men, many women lose their hair. According to the American Academy of Dermatology, 30 million women in this country have hereditary hair loss, compared with 50 million men. But many additional women experience thinning hair that results from menopause or health problems.
However, the effects of alopecia reach far beyond symptoms of depression and include anxiety, obsessions, dissatisfaction with one’s appearance, and low self-esteem (Al-Mutairi and Eldin, 2011, Dlova et al., 2016, Hunt and McHale, 2005, Schmidt et al., 2001). There can be significant disturbance in a patient’s social life because they may change their hair style, clothing, or avoid social meetings (Al-Mutairi and Eldin, 2011). One study reported that 40% of surveyed women described marital problems and 63% had career-related issues that they ascribed to their hair loss (Hunt and McHale, 2005). These effects seem to occur regardless of patients’ age, race, or degree of hair loss (Dlova et al., 2016, Hunt and McHale, 2005, Schmidt et al., 2001). Another study of more than 200 women found that this psychologic morbidity occurs with equal frequency in women whose hair is typically covered by a headscarf (Erol et al., 2012).

Staphylococcal blepharitis causes lid margin inflammation and folliculitis which destroys the hair follicle resulting in madarosis[30] which is usually non-scarring,[10] but occasionally may be scarring, especially if long standing.[15] Seborrhoeic blepharitis is very often associated with secondary bacterial infections and can result in madarosis either due to associated staphylococcal infection or due to rubbing caused by itching.

Traumas such as major surgery, poisoning and severe stress may cause a hair loss condition known as telogen effluvium, in which a large number of hairs enter the resting phase at the same time, causing shedding and subsequent thinning hair in men and women alike. The condition also presents as a side effect of chemotherapy. While targeting dividing cancer cells, this treatment also affects hair’s growth phase, with the result that almost 90% of hairs fall out soon after chemotherapy starts.


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.  
This manifests in childhood with chronic lower eyelid dermatitis and is often associated with other types of allergic disorders.[36,37] The ocular features are eyelid dermatitis, Dennie-Morgan fold (an infraorbital fold or line due to lid edema in atopic dermatitis), keratitis, and a frequent association with keratoconus and cataracts. Loss of lateral third of eyebrows (Hertoghe sign)[38] is seen in atopic dermatitis due to constant scratching and rubbing.
Eyebrow thinning that manifests in irregular patches, especially accompanied by red and itchy skin, may indicate atopic dermatitis. This condition—commonly called eczema—can occur just about anywhere on the body and is usually hereditary. People with atopic dermatitis may be more sensitive to topical irritants, but eczema just from topical irritants is called allergic contact dermatitis or irritant contact dermatitis. While you wait on the appointment with your dermatologist, you can help ease eczema around the eyebrows by switching to mild soaps or a soap-free facial cleanser, and applying an intensive facial moisturizer within three minutes after bathing.

The normal cycle of hair growth lasts for 2 to 6 years. Each hair grows approximately 1 centimeter (less than half an inch) per month during this phase. About 90 percent of the hair on your scalp is growing at any one time. About 10 percent of the hair on your scalp, at any one time, is in a resting phase. After 2 to 3 months, the resting hair falls out and new hair starts to grow in its place.
Yes. Hyperandrogenism, a medical condition characterized by excessive production of male hormones called androgens, can cause hair loss in affected women. The most common cause of hyperandrogenism in women is functional ovarian hyperandrogenism, also known as polycystic ovary syndrome. In addition to hair loss, other signs include obesity, acne, and irregular menstruation, and it is one of the most common causes of infertility.
Androgenic alopecia, hair loss when androgen levels are not too high, is an indicator of inflammation. Hair loss is just one sign of inflammatory issues like Celiac disease or gluten intolerance. Naturopathic Doctor Lara Bridden says, “Inflammation hyper-sensitizes your hair follicles to a normal amount of androgen. Reduce inflammation by avoiding food sensitivities such as wheat and/or dairy, and by correcting intestinal permeability.”

The term superciliary madarosis is often used describe abnormal eyebrows and eyelash hair loss which can be partial or total. Depending on the cause, the can be weird since besides the hair breaking and falling out easily, some people may end up with a part, half, inner, outer third or one on or both eyebrow missing. In fact,  thinning at ends is common.
Changing the shape, thickness and length of the eyebrow is a commonly practiced beauty technique. Some people even remove the eyebrow entirely only to replace it with a pencil-drawn mark (eyebrow pencil). As with any part of the body, repeated irritation can eventually lead to hair loss. Sometimes this is due to manual trauma, chemicals from cosmetics or even infections that arise when breaks in the skin occur. While eyebrow modification will not stop as a commonly practised beauty technique, it should at least be minimized.
I can't tell you how many women come into my office fretting about the fact that they've over-plucked. While this is certainly a possibility (plucking the eyebrows damages the hair follicle, and with repeated plucking, the follicle can get damaged to the point that it can no longer produce a hair), there are actually a number of both external and internal causes and conditions that can lead to temporary or permanent loss of eyebrows.
Giorgos Tsetis: When you want to solve an issue, you must first thoroughly understand the problem. A lot of times, especially in the pharma world, everybody is trying to identify the magic pill that targets a single trigger. But, that's the exact reason there hasn't been a drug that holistically and indefinitely ends the problem. You can't zero in on one specific trait or symptom, you really have to solve for the many causes. When it comes to hair loss for men and women, there are several causes that disrupt the natural hair growth cycle. Basic vitamins and minerals only act as a temporary bandaid for hair health deficiencies, which is simply not enough. Hair loss and thinning hair means your body is imbalanced and there's something off, because hair follicles are mini organs.

For women going through menopause, the cause of hair loss is almost always related to hormonal changes. However, there are many other factors that can contribute to hair loss during menopause. These include extremely high levels of stress, illness, or a lack of certain nutrients. Diagnostic blood tests that can help rule out other causes of hair loss include thyroid tests, and/or a complete blood count.
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 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. 
Scurf refers to the scales and greasy crusts that accumulate along the hair shaft and indicates the presence of seborrhea.[26,27] Collarettes are composed of hard fibrinous scales[25,28] surrounding each individual eyelash. They travel upward along with the growth of the lashes and are indicative of staphylococcal infection. Sleeves or cylindrical dandruff comprise scales that form a cuff around the lash root and are connected with it, in contrast to greasy scales which are not connected to the lash root.[29] Sleeves indicate infestation with Demodex folliculorum.

Alopecia areata is a patchy hair loss associated with immune disturbances. In this condition the immune system attacks the hair follicles thereby impairing hair growth. It is more likely to occur in people with other immune-related disorders and has also been linked to psychological stress as well as with certain drugs like some types of ARVs used for HIV treatment. Alopecia areata does not only affect the scalp as commonly thought. The eyebrows and beard area, as well as hairy parts anywhere on the body may be affected.


Liver support: is necessary to eliminate unneeded wastes from the body. Everything we take in is processed through the liver and toxins are broken down into water soluble byproducts so they can be moved into the intestine and pulled into the stool for elimination. Foods like cruciferous vegetables (kale, broccoli, collard greens) and lemon support the liver detox pathways. Herbs like milk thistle, dandelion root, and burdock root help to support  liver cleansing. 

Hair loss may also occur due to dieting. Franchised diet programs which are designed or administered under the direction of a physician with prescribed meals, dietary supplements and vitamin ingestion have become popular. Sometimes the client is told that vitamins are a necessary part of the program to prevent hair loss associated with dieting. From a dermatologists’s standpoint, however, the vitamins cannot prevent hair loss associated with rapid, significant weight loss. Furthermore, many of these supplements are high in vitamin A which can magnify the hair loss.
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.
“The biggest mistake I see is people being too heavy handed with their eyebrow products,” says Megan Studabaker, a registered nurse and owner of Finespun Brow Design in Scottsdale, Arizona. “I recommend applying products in hair-like strokes, versus just filling in with powder because it often gets smeared and messy which isn’t achieving the polished look you are going for.” I’ve had good luck using Benefit Precisely, My Brow Pencil ($24) and Foolproof Brow Powder ($24).
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.
Many unpleasant things can happen to your body as you age. Losing eyebrow hairs is one of them. When you get older, your eyebrows may naturally become thinner as you experience hair loss. Though aging is inevitable, there are some ways you can help to prevent hair loss as you get older. Managing your stress, maintaining good nutrition, hydrating your skin and not exposing your eyebrows to excessive trauma, such as waxing, plucking, or threading, should help prevent eyebrow loss.
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]
