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.
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.

An unhealthy gut is also a common source of inflammation and that alone can contribute to hair loss. But lack of robust digestion and a healthy gut bacterial environment will not only lead to nutrient deficiencies that impact hair health but an imbalanced impacting all other hormones related to hair loss such as low thyroid, poor estrogen metabolism and elevated cortisol.
Physicians such as dermatologists and plastic surgeons have long recommended essential vitamins and supplements for hair growth to women and men. Now read why top medical experts including Dr. Craig Ziering and Dr. Steven Dayan have been telling their patients for years about Viviscal hair growth supplements to help grow thicker, longer and healthier looking hair.

Furthermore, Penn dermatopathologists developed an even more advanced method called the HoVert technique for diagnosing hair loss and other disorders from a scalp biopsy. The technique uses a unique horizontal and vertical testing approach that provides a greater amount of information to the referring dermatologist than standard industry longitudinal scalp biopsies.
“…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…”

Thyroid hormone receptors were detected in both dermal and epithelial compartments of the human pilosebaceous unit.[48] T4 and T3 decrease the apoptosis of hair follicles and T4 prolongs the duration of anagen in vitro.[49] Thyroidectomy delays initiation of anagen. Administration of thyroxine advances anagen, initiation of which is however delayed once toxic doses are given. Therefore, ratio of telogen to anagen hairs is increased in hypothyroidism as well as hyperthyroidism.[50] Thus, the hair follicles are affected in thyroid disorders, and madarosis is caused due to disturbances in hair cell kinetics. Hypothyroidism is associated with generalized hair loss probably due to coarse, dull, and brittle hair with reduced diameter.[51] The eyebrows and eyelashes may also be lost. Loss of lateral one-third of eyebrows known as Hertoghe sign[38] is a characteristic sign of hypothyroidism.[52] Some people also refer to it as Queen Anne's sign,[53] after Anne of Denmark whose portrait with shortened eyebrows has been interpreted by some as indicative of the presence of goiter, even though such a fact has not been proved by any known sources of information. Madarosis may even be the presenting sign in hyperthyroidism.[21] In hyperthyroidism, there is thinning with breaking off and shortening of hair.[54] Madarosis can also occur in hypopituitarism, hypoparathyroidism,[21] and hyperparathyroidism.[55]

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.


Eyelash hairs are usually present in two to three rows, and are short, thick, and curved in appearance. They are set obliquely, anterior to the palpebral muscle. The upper eyelashes are more numerous and curve upward, while the lower eyelashes curve down in order to avoid interlacing during eyelid closure. Eyelash cilia are unique in that they have no erector muscles. Eyelash hairs are oval in all races.[7]

Hansen's disease, also known as leprosy, is an infection of the skin and nerves caused by the bacterium Mycobacterium leprae. The disease often affects the skin of the eyebrow region, leading to loss of sensation and permanent loss of the eyebrow hairs. There are numerous other rare and uncommon causes of eyebrow hair loss, including vitamin A toxicity, nutritional disorders and other dermatological disorders. If you experience loss of eyebrow hair, see your doctor to evaluate the cause and to discuss a treatment plan.

Although these statistics would suggest a more collective effort amongst industry leaders to proactively find a way to fix this problem, the trends have revealed the opposite. Due to an ecosystem of loose regulations, cheap supplement sourcing, and a business model built on overselling to a dependent audience – the industry has been fueled by driving profits instead of solving problems. When one Wilhelmina model noticed he was quickly losing hair at a pivotal point in his career, the search for an effective product revealed the surprising lack of safe, natural and healthy solutions.


Research suggests that hair loss during menopause is the result of a hormonal imbalance. Specifically, it’s related to a lowered production of estrogen and progesterone. These hormones help hair grow faster and stay on the head for longer periods of time. When the levels of estrogen and progesterone drop, hair grows more slowly and becomes much thinner. A decrease in these hormones also triggers an increase in the production of androgens, or a group of male hormones. Androgens shrink hair follicles, resulting in hair loss on the head. In some cases, however, these hormones can cause more hair to grow on the face. This is why some menopausal women develop facial “peach fuzz” and small sprouts of hair on the chin.
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.

Hormones are cyclical. Testosterone levels in some men drop by 10 percent each decade after thirty. 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 experiencing a long-term slowdown of hair loss (and a long-term increase in hair growth) while on a treatment that controls hair loss.
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.

A. I'd say 25 percent get very good results. For another group, it just means that the situation is not getting worse, which no one ever considers a success. If you are thinking about it, you should start early. Minoxidil is not for everyone. … It can take at least six months to work — which doesn't fit most patients' time frames. It can stimulate facial hair or cause a rash on the scalp. It's not a miracle, but it's the only FDA-approved medication we have and it's been that way for 30 years. These are things we struggle with.
If you’ve overplucked your brows too many times, you may have caused trauma to the follicles in the meantime, signalling not only those hairs you plucked to stop growing back, but also the hairs in surrounding areas. The good news: If the hair follicles aren’t dead, they can possibly be shaken from their resting state with a good brow enhancer. (like WINK  yes of course, we have to say it). There’s no sure bets, but it’s worth a try–plus Wink has a money-back guarantee!
When compared with no treatment, patients who received ethinyl estradiol 50 μg and cyproterone acetate 2 mg with cyproterone acetate 20 mg on days 5 to 20 of the menstrual cycle for 1 year had a significant increase in their percentage of anagen hairs with trends toward a larger shaft diameter of full anagen hairs and a decreased number of hairs that were less than 40 microns (Peereboom-Wynia et al., 1989). A 12-month randomized control trial of 66 women compared treatment with topical minoxidil 2% plus an oral contraceptive (ethinyl estradiol 30 μg + gestodene 75 μg) with treatment with cyproterone acetate 50 mg plus an oral contraceptive (ethinyl estradiol 35 μg + cyproterone acetate 2 mg) and demonstrated that treatment with cyproterone was more effective in hyderandrogenic patients but otherwise less effective (Vexiau et al., 2002). Side effects of cyproterone acetate include weight gain, breast tenderness, and a decreased libido (Kelly et al., 2016). Hepatotoxicity and development of multiple meningiomas may occur when doses exceed 25 mg daily (Medicines and Healthcare products Regulatory Agency, 2009). Cyproterone acetate is used widely in Europe and Canada, either in an isolated form or in combination with ethinyl estradiol, but it is only available in the United States as an orphan drug for the treatment of hirsutism (Carmina and Lobo, 2003, Jurzyk et al., 1992, Kelly et al., 2016). Cyproterone acetate is classified as pregnancy category X.

It is an impulse-controlled disorder characterized by compulsive plucking or breakage of hair.[91] The most frequent site of hair pulling is the scalp, but the eyebrows, eyelashes, and pubic hair may also be involved. Trichotillomania manifests in eyelashes and eyebrows as irregular patches of alopecia containing hairs of varying lengths. Inflammation, scarring, and atrophy are conspicuous by their absence. Patients often attempt to conceal their alopecia by cosmetological camouflage. In case of a diagnostic dilemma, histological features such as increased numbers of catagen hairs, pigment casts, and traumatized hair bulbs provide a clue.


There are a couple of other reasons why soy is a great choice too. For one, it is really good for you, protecting your cardiovascular health by reducing your LDL cholesterol levels. For another, soy is an easy, cost-effective choice. Instead of searching everywhere for quality herbal supplements you are unfamiliar with, you can simply add some soy milk to your diet or eat some tofu.


What’s more likely is that telogen effluvium is at play (again). In addition to hormone fluctuations, this type of hair loss happens when there is a drastic dip in protein in the diet or sudden weight loss. For example, if you are sick and can only consume liquids for a month. “If you have protein levels that drop dramatically, your hair follicles go into hibernation, and you can see sudden acute hair loss that shows up three to six months later,” says Dr. Katta.
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.”
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.

The recipient sites in the eyebrow can be conveniently made with 20 to 22-gauge needles parallel to the skin, so that hair grows flat on the skin and does not stick out from the face. About 150 hairs are required for a full eyebrow graft. Poddar et al. described good results with a technique of creating recipient tracks with the erbium yttrium aluminium garnet laser.[202]


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.
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.
If you are suffering from hair loss on your head AND your brows, you might be suffering from a protein deficiency of some sort. A supplement like Viviscal (available here), which is packed with marine protein, could help your condition. Viviscal has been shown to treat alopecia areata, as well as androgen-related hair loss (Journal of International Medical Research, 1992; FutureDerm). It will take some time, though: changes in protein in the diet have been shown to correspond with protein in the hair within 6-12 months (American Journal of Physical Anthropology, 1999; Futurederm).

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.

Well, maybe that’s a new adage from instagram, but it’s true all the same: eyebrows are the essential defining feature of every woman’s face. That’s exactly why eyebrow loss can feel like a death sentence to the beauty-conscious woman. With thick, lush eyebrows in style, eyebrow loss can feel more traumatizing than ever. Hair one day, gone the next!

Check for hypothyroidism. If you also notice unexplained weight gain, chronic fatigue, feeling depressed, or feeling colder than usual in low temperatures, your thyroid gland may not be producing enough hormones. You may also notice your periods getting heavier or becoming sporadic. Hypothyroidism is most common in women, especially over age 50, and it can be treated with a synthetic hormone.[31]
Complete Belgravia's online consultation if you are unable to visit one of our London clinics. The questionnaire should take no more than 10 minutes to complete and will provide our hair loss specialists with all the information required to recommend an effective course of home-use treatment. For those who live in or around London, we always recommend a clinical consultation. 

Both of these hairy issues are related to excess androgens that are part of PCOS.  Our hair follicles respond overzealously to testosterone creating both hair loss and hair growth. This is because the follicles on the face tend to stretch and grow causing the hair to get stuck and not fall out when they should. Conversely, the scalp hair follicles actually shrink in response to androgens and the hair can fall out or just not be as robust.
A. Steroids are not for female pattern hair loss but are sometimes used for alopecia areata (spotty hair loss that is different than hair loss due to genetics and aging). Laser combs? There are some reports that low-level light therapy could stimulate hair growth in some people. It's something to try when people feel like they have no other good options. At $350, it's expensive and I'm not sure it's worth the money, but it is safe.

So, if you have a similar paranoia—fear not! Losing strands is totally normal. But Dr. Wexler is quick to add that things like over-tweezing (it causes scarring to the follicles), waxing, severe weight-loss, stress, excessive touching, hormonal changes, and auto immune disease can cause irregular brow hair loss. If you believe your case may be extreme, it's best to see a specialist.
