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.
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.

Additionally, two other considerations are important for a patient who receives treatment for FPHL. First, there is a set of reasonable expectations in patients. Maintaining the current hair density can be considered a successful treatment because women tend to have further thinning as they age (Harfmann and Bechtel, 2015). Second, it is important to ensure that patients understand that progress is slow, and months or years can be required to see a significant improvement (Boersma et al., 2014, Yeon et al., 2011). In our practice, we wait at least 6 months to assess treatment efficacy.
The startup recently closed its Series A round of funding, with Unilever Ventures, the investment and private-equity vertical of the consumer goods company, stepping in as the lead investor. Unilever was introduced to Nutrafol through investment platform, CircleUp.

With continued investment in research and clinical studies, Nutrafol is poised to take the lead in the fragmented multibillion-dollar global hair loss industry.
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.
In order to prevent drying and breakage, it’s best to stay away from heat tools, such as hair dryers and straightening irons. Extensions and other styling methods can also weaken your hair and cause early hair loss. If you must dye your hair, choose an all-natural hair color. Artificial chemicals found in dyes and perms can compromise your scalp and hair health. When you wash your hair, always use a nourishing conditioner to keep your scalp healthy and promote healthy hair growth.
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.
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.
If you’ve undergone chemotherapy recently, you know the effects that it has on your hair, including your brows and lashes. First of all, I want to point you to this awesome resource by FairyHairs (click here), that shows in intervals, with pictures, what you can expect with regrowing your hair after chemo (Thank you, Jenny Mealy!). The article also includes ways to regrow your hair after chemo.
Unfortunately, there’s no magic solution, pill or product that will correct hair loss entirely. But if you think of your hormones as a cast of characters, knowing which ones are leading the show and which ones are only playing a supporting role can help you get to the bottom of the issue. If you haven’t already, take my free hormone quiz – it can help you determine what tests you may want to request from your doctor and which lifestyle or dietary changes may benefit you most. In the meantime, manage your stress levels and get enough sleep. This will help with general hormone balance and can protect your precious locks from any further damage.
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.
Postpartum hair loss is related to the drop in estrogen experienced after giving birth. During pregnancy, the body has higher levels of estrogen (and progesterone) and estrogen increases hair’s “resting phase,” or the time hair stays on your head before naturally falling out (which is what accounts for the 100 or so hairs that healthy heads shed every day). When estrogen drops after pregnancy, all the hair that had been “resting” starts to shed. Post-pregnancy hair loss is usually temporary, lasting for several months.
These important micronutrients, which are all essential for hair health, are part of my Balance Supplements. And even if you eat a healthy, phytonutrient rich diet, you might not have optimal levels of the vitamins and minerals you need to promote hair health. Environmental factors beyond our control, from the mineral-depleted soil in which most of our food is now grown to shifts in growing practices that have reduced the amount of vitamins and minerals in various foods, can leave us eating a picture-perfect diet and still deficient in certain micronutrients.
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.
Most of us look at the eyebrows as a patch of hair that has an aesthetic purpose and it is often shaped for cosmetic purposes. Although the exact purpose of the eyebrows is not conclusively understood, it is believed to be prevent water or sweat from falling on to the eyes itself. For most people its function is of little concern compared to its cosmetic purpose. As with hair anywhere on the body, eyebrow hair and the follicles from where it arises can be prone to the same diseases and disorders which may lead to hair loss..
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.
Around 30 million U.S. women will experience hereditary hair loss, or female pattern baldness (androgenetic alopecia), while others will struggle with situational hair loss, brought on by medical conditions, medications, poor health and nutrition, environmental factors such as smoking and sun damage, or even from adverse reactions to hair care products or treatments.
Hair loss is one of the most irritating and worrisome issues anyone would ever have to meet with. It is obvious that there are various reasons which may cause hair loss in individuals. One of the causes of hair loss can be a low level of estrogen hormone. There is a connection between estrogen and hair loss. In this current article, we will talk about if low estrogen can cause hair loss and also know of ways to prevent it. Hope this would be a beneficial read for you.
Androstenedione, which is mostly produced in the ovary and adrenal glands, is converted to testosterone by 17β-hydroxysteroid dehydrogenase. Testosterone then circulates throughout the body to reach its target tissues. Androgen-metabolizing enzymes have been found in many parts of the hair follicle (Table 1; Bolognia et al., 2012). The presence of those enzymes makes the pilosebaceous unit a site of androgen metabolism and synthesis (Fazekas and Sandor, 1973). Circulating free testosterone either binds to intracellular androgen receptors in the hair bulb and dermal papilla, which facilitates miniaturization of the follicle, or is metabolized into dihydrotestosterone (DHT) by the enzyme 5-alpha-reductase. DHT then binds the same receptor but with much greater affinity (Kaufman, 2002, Levy and Emer, 2013). Of the androgens depicted in Figure 1, only DHT and testosterone bind to androgen receptors (Burger, 2002).

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.

It’s precisely because vitamins and minerals are SO critical to hormonal healing—and to healing the devastating side effects that come with it, like thinning hair—that I created the FLOLiving Balance Supplements. The supplement industry has very little oversight and I saw so many women waste money on supplements that at best didn’t work and at worse contained dangerous ingredients.

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.

Hormonal changes are a common cause of female hair loss. Many women do not realize that hair loss can occur after pregnancy or following discontinuation of birth control pills. It is important to remember that the hair loss may be delayed by three months following the hormonal change and another three months will be required for new growth to be fully achieved.
A decline of estrogen, whether due to menopause or other hormonal imbalances, can also affect hair growth. You'll experience a thinning or loss of pubic hair as well as hair on your scalp if you have low levels of estrogen in your body. You might also experience unwanted hair growth on your face during menopause, when your estrogen levels are at their lowest. This phenomenon occurs because the lack of estrogen leaves you with a hormonal imbalance of sorts; you have more androgens, or male hormones, than female hormones in your body, which contributes to some male-like symptoms such as body and facial hair.

If you have any more concerns about licorice, just remember that licorice candies are a Dutch treat, and overseas, plenty of Dutch people are consuming the stuff on a regular basis with no ill effects. In moderation, this may be an effective (and tasty) way to raise your estrogen levels. While you are at it, you can reduce any heartburn problems you happen to have.
The study in question, which was first published in the journal PLOS Genetics earlier this year, analyzed the hair growth of 52,000 men between the ages of 40 and 69 in the UK. The numbers: 32% of the men said they did not experience any hair loss at all. 23% said they experienced a little bit. 27% had moderate hair loss, and the last 18% said they were suffering from severe hair loss.
Over-plucking or nutrient deficiency can be easily solved on your own with behavioral changes and nutritional supplements, but if you suspect that your thinning eyebrows are caused by a health problem, please see a doctor right away for treatment. Do not attempt to address hypothyroidism, eczema, or alopecia areata without the guidance of a medical professional.

DLE is an autoimmune condition and is the most common form of chronic cutaneous lupus erythematosus.[35] Clinically, the lesions start as discoid erythematous patches which then develop into plaques with follicular plugging and scaling. Eyelid findings include blepharitis, lid scarring, entropion, and ectropion. Scaly plaques on the eyelids with loss of hair follicles results in madarosis[60] [Figure 3]. Numerous studies have reported the mimicking of a chronic blepharitis by DLE.[35,61–63] A high index of suspicion is necessary in such cases, where the diagnosis is very often delayed by months to years.[35] Biopsy with histopathological examination should be done to confirm the diagnosis. Treatment with hydroxychloroquine results in a regrowth of the eyelashes.[61]


Balancing your hormones is not an easy process, whether you are in perimenopause, menopause, or post-menopause. You may find that just one of these herbs is sufficient to do the trick, but in many cases you will achieve the best results by taking a combination of herbs. Start gradually and track your results carefully to make sure you are choosing the right products to balance and adjust your particular hormone profile.

A. I think it's a personal preference, but why is a cosmetic solution such a big deal? To use sprays, powders and hair extensions? It doesn't address the problem, but it can do wonders for your self-esteem. I see patients who are extremely depressed, and this is ruining their life. We always have hope for that miracle solution, but it's very hard to do research studies. … As much as this affects people's mentality, there's not a lot of (National Institutes of Health) funding because hair loss isn't killing anyone.
Your body needs to be hydrated in order to function properly. Load up on H2O all day long and pass on juices, sodas, and other flavored drinks that contain more sugar than your body needs. The amount of water needed varies from person to person and depends on various factors, including overall health and exercise intensity. As a general rule, however, you should aim to have eight 8-ounce glasses of water per day.
Reduce stress. When you are stressed, your body starts shutting down processes that aren’t necessary for survival. This shutdown can occur with physical stressors, like surgery or an illness, and emotional stress, which often manifests as physical symptoms. Loss may occur up to three months after the stressful event and may take another three to grow again.[24]

If you’re in good health but would like your brows to be a bit fuller, you’ve got plenty of options. Massage a bit of moisturizing coconut oil into your eyebrows about three times weekly, to make for healthier, shinier and more eye-catching hair. Eyebrow pencils remain an effective choice as a go-to filler; go a shade lighter than your brows for a natural look. To shake things up a bit, opt for a brow shadow. These powders, which look like eye shadow, go on with a brush and fill in thin or patchy brows with a soft and subtle fullness.
No one wants to lose their hair, but for a woman it is particularly distressing. While men can look perfectly presentable — even sexy — with their exposed scalp, no such options exist for the 30 million American women who grapple with thinning tresses. Dr. Maria Colavincenzo, a dermatologist at Northwestern University Feinberg School of Medicine, has a practice that specializes in preserving those precious strands — especially in cases of androgenetic alopecia, a hereditary condition that causes hair loss, mainly on the top and crown of the scalp. Without an appointment, she answered some of our questions:
Thyroid Dysfunction: Since the thyroid gland regulates many body functions by releasing hormones, any disruption in its functioning can cause loss of hair, including eyebrow hair. If your thyroid is underactive, it could cause you to lose the outer third of your eyebrow. The only way to treat thyroid dysfunction is through medication. However, there’s still no guarantee that your eyebrow hair will grow back.

Alopecia areata is a chronic autoimmune disease in which the immune system erroneously attacks the hair follicles, causing inflammation and temporary hair loss. Any hair-bearing skin site can be affected by alopecia areata, including the eyebrows. Treatment commonly involves corticosteroid injections into the site of eyebrow loss. Eyebrow hairs usually grow back, but may be a different color or texture than the lost hairs.
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.
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.
Hair loss is something that everyone experiences sooner or later, but some get it earlier than others. Losing hair prematurely can be traumatic. Because of that, there is an infinite number of products that claim to cure and reverse the problem. But what if you could find out the likelihood that you will experience hair loss so that you could prevent it before the symptoms even showed? Researchers in the United Kingdom have reportedly found a way to predict who is at risk.
“When I went in for my Bosley consultation, my senior counselor was the one who walked me through the procedure. He also had had the procedure done, and his results were phenomenal. And I was thinking, ‘Wow, if I can get that, that’s what I’m looking for.’ He really got it — he understood me. He understood what I went through, and that was really important to me.
But there’s load of hope! Just know it takes time and first and foremost it takes knowing the cause of the hair loss. That’s the only way to get on top of the issue. The type of hair loss you have (all over, patchy, thinning, losing only at temples, lack of new hair growth after shedding, etc.) points to the underlying cause of your shedding locks. So always start there. 

The leading cause of hair loss in men is male pattern baldness, also known as androgenetic alopecia. This occurs in men whose hair follicles are sensitive to the hormone dihydrotestosterone, or DHT. Over time, DHT-sensitive hair (usually found on the top and front of the head) becomes weaker and finer and eventually stops growing. Most men have DHT-resistant, healthy hair follicles around the sides and back of their head. This is why so many men have a horseshoe pattern on their head.
Another reason why hair falls out is lupus. Lupus is an autoimmune disease that may make your immunity system begin attacking your various healthy body tissues. According to Medical News Today, “this results in symptoms such as inflammation, swelling, and damage to joints, skin, kidneys, blood, the heart, and lungs”. It can also attack eyebrow follicle resulting sudden hair loss and including brows.
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.

See a dermatologist for itchy skin or rashes around your brows. These patches may indicate a skin infection or interaction with a new beauty product or environmental trigger. You could also have inflammation from dermatitis or psoriasis.[32] These conditions don’t actually cause hair loss, but they can lead to it if you rub and scratch the affected areas.
Reduce stress. When you are stressed, your body starts shutting down processes that aren’t necessary for survival. This shutdown can occur with physical stressors, like surgery or an illness, and emotional stress, which often manifests as physical symptoms. Loss may occur up to three months after the stressful event and may take another three to grow again.[24]
Madarosis of non-scarring type is commonly seen in alopecia areata which is a hair-specific autoimmune disease associated with patchy loss of hair.[56] It presents as round or oval patches of non-scarring hair loss. Madarosis occurs as isolated involvement [Figure 2] or as a part of alopecia universalis.[57] When alopecia areata involves the eyelashes exclusively, there is rarely involvement of other parts of the body.[58] Alopecia areata can involve both the eyelids without scalp involvement also.[59] Short exclamation mark hairs are pathognomonic for alopecia areata.
In an article on menopause, the University of Maryland Medical Center states, “Estrogen loss can contribute to slackness and dryness in the skin and wrinkles. Many women experience thinning of their hair and some have temporary hair loss.” Meanwhile, this study reports, “It has long been known that estrogens also profoundly alter hair follicle growth … the time has come to pay estrogen-mediated signaling the full attention it deserves in future endocrinological therapy of common hair growth disorders.”
Other drugs commonly attributed to causing madarosis are miotics, anticoagulants, anti-cholesterol drugs, antithyroid drugs, propranolol, valproic acid, boric acid, and bromocriptine.[21,99] Anticoagulants in high doses have been found to produce loss of scalp, pubic, axillary, and facial hair with loss of eyebrows after a latent period of a few weeks of treatment with dextran and heparin.[100] Propranolol can cause diffuse alopecia along with loss of eyebrows due to telogen effluvium,[101] usually after three months of therapy.[44] Loss of medial aspect of eyebrows can be seen in fetuses exposed to valproic acid.[102] Diffuse alopecia including that of eyebrows has been described due to chronic ingestion of mouthwashes containing boric acid. There was complete reversal following stopping the practice.[103] Levodopa has been noted to cause severe diffuse alopecia within three months of daily use.[104] Hair loss can occur soon after starting topical minoxidil therapy (due to detachment of club hairs following resting hairs reentering anagen), and after cessation of therapy (due to telogen effluvium).[98]
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.
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.”
Hormones are cyclical. Testosterone levels in some men drop by 10% each decade after age 30. Women's hormone levels decline as menopause approaches and drop sharply during menopause and beyond. The cyclic nature of both our hair and hormones is one reason hair loss can increase in the short term even when you are having a long-term slowdown of hair loss (and a long-term increase in hair growth) while on a treatment that controls hair loss. 

Your body has an amazing capacity to send out signals when it’s in trouble, and your eyebrows are no exception. Aging causes harmless thinning of the hair, in general, so it may contribute to less-than-lush eyebrows. But when the thinning is accompanied by other symptoms, a visit to your doctor or dermatologist is in immediate order. With timely treatment, your brows—and, more important, your body—can make a steady and healthful recovery.
Yes. If you wear pigtails or cornrows or use tight hair rollers, the pull on your hair can cause a type of hair loss called traction alopecia (say: al-oh-pee-sha). If the pulling is stopped before scarring of the scalp develops, your hair will grow back normally. However, scarring can cause permanent hair loss. Hot oil hair treatments or chemicals used in permanents (also called “perms”) may cause inflammation (swelling) of the hair follicle, which can result in scarring and hair loss.

Scalp hair loss may be a common complaint among men and women, but in my practice, loss of eyebrow hair is a major concern among my female patients. Because eyebrows frame the face, hair loss in this area can dramatically change one's appearance, and since eyebrow hair loss is not easily concealed, it can be, for some women, an even more devastating loss than scalp hair loss.


Testosterone replacement is becoming popular for men. Cotsarelis warns that this may accelerate hair loss. Propecia might help -- but because it prevents testosterone breakdown, it might affect the dose of male hormone replacement therapy.

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.

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.
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.
