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. The investment from Unilever Ventures, along with other strategic partners, will be used to advance research efforts, product development and expand within the medical, salon and e-commerce channels. With continued investment in research and clinical studies, Nutrafol is poised to take the lead in the fragmented multibillion-dollar global hair loss industry.
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.

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.
Accurate placement of the grafts is necessary to ensure a good cosmetic result. In the medial third, the needles should be inserted parallel to the brow axis.[203] The follicles should point toward the tip of the nose and the hairs should converge toward each other in the other two segments, that is, the bulbs in the upper part point toward the forehead and in the lower part toward the other eyebrow.[204]
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.
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.
This is a diverse group of rare disorders that destroy the hair follicle, replace it with scar tissue and cause permanent hair loss. The hair loss may be accompanied by severe itching, pain and burning, and may progress rapidly. In other cases, the hair loss is gradual, has no symptoms and is unnoticed for long periods. It is also sometimes known as scarring alopecia and can occur in otherwise healthy men and women of all ages.

MICHAEL REED, MD: Over-the-counter minoxidil, which is the brand Rogaine, is FDA approved. It's been shown to be effective in scientific studies. Propecia is the new drug on the block, and that probably is more effective. It's a pill that you take once a day, and that has been shown to slow down hair loss and grow hair in a significant number of individuals. Most of the other preparations that are heavily advertised or marketed are not proven to be effective.


Estrogen, the power player in women’s bodies, is your friend when it’s appropriately balanced. It makes you feel energized, helps stabilize your moods and contributes to a healthy sex drive. Yet too much estrogen, which can be caused by weight gain, perimenopause or toxicity from exposure to endocrine disruptors (which are rampant in our food, water and plastic products), can lead to thinning hair. During and after pregnancy, for example, estrogen levels peak and then dip, causing sudden hair loss for many 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.
Eyebrow loss, also known as superciliary madarosis, can occur with a variety of medical conditions. Madarosis can affect one or both eyebrows with partial or complete hair loss. Infections, chronic skin disorders, hormone disturbances, autoimmune diseases and medications are among the many medical reasons for eyebrow loss. In most cases, identification and treatment of the underlying condition leads to regrowth of the eyebrows. Permanent eyebrow loss can occur with disorders that permanently damage the hair follicles.
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.

Thinning hair, noticeable bald spots, receding hair line, large clumps of hair showing up in your hair brush or shower drain, these are typically things you hear about from men, not women. More and more though, we are contacted by women who are experiencing hair loss who want to know if this is a sign of something wrong with their hormones and how they can fix the problem. Fortunately, hair loss is not a sign of infertility, but is a side effect of hormonal imbalance which can impact your fertility.
Cut the fast-food diet and start getting some whole food in your life. The less processed the better; as my mom says “as close to nature as possible.” Healthy skin and hair start with a healthy diet. Aim for a diet rich in Vitamin C, Vitamin A, Vitamin E, B Vitamins, lean protein and Essential Fatty Acids. EFAs can be found in walnuts, salmon, flax seed, and most seeds. EFAs have been shown to increase prostaglandin production in those with a deficiency; prostaglandin is what prompts your lashes and brows to grow.
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.
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.
It takes more than just an apple a day to keep the doctor away; if your diet lacks the key vitamins A, B, D and E or nutrients such as iron, calcium or the amino acid L-lysine, your hair may suffer. Nutrient deficiency doesn’t just affect the eyebrows—it may lead to hair loss on the scalp, feelings of fatigue and physical weakness, lightheadedness or inhibited concentration, heart palpitations and pale skin, among other serious symptoms.
Giorgos Tsetis: Another reason Unilever was inspired to partner with us is that we really target three channels. Direct-to-consumer is one, then we target physician channels and salon channels; which are the hardest to convince. There's liability involved, so there's no doctor in the world who is going to recommend or endorse a product they don't believe in. We have about 350-400 physicians currently selling the product. A large amount of these doctors are thought-leaders or experts in the space, so they are known to speak about this issue on a world stage when it comes to new innovations. We also have each of the top 20 hair salons in the country carrying the product. There's a ton of celebrities who use the product as well. It is a premium product, but we've still made it affordable for people. When you look at other products on the market, our price point is comparable. We're also working on special programs for people in need who can't normally afford the product. If somebody is motivated, serious and really needs it -- we work to make sure they can get the product, and seek to serve as many people as possible.
Taking estrogen supplements as part of a hormone replacement therapy regime has its effects on your hair as well. Women can treat a type of hair loss called androgenic alopecia, associated with low estrogen and progesterone, by replacing these hormones artificially. Dosages of synthetic estrogen should be monitored regularly -- abnormal hair growth is a possible side effect of one kind of hormone replacement therapy, called esterified estrogens.

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.
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.
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 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. 

Mistakenly thought of as a male disease, around 40% percent of women will suffer from some form of hair loss by the age of 50. A woman’s hair is an important part of her aesthetic make-up. It represents her style and taste, and frames her face while accentuating her best features. Unfortunately, most physicians don’t have answers or solutions for women who begin to lose their hair.  Plano, TX hair restoration surgeon, Dr. Joseph Yaker, understands that this can be extremely catastrophic to a woman’s self-confidence, body image and quality of life. Clinical studies have shown that psychiatric disorders such as depression and anxiety are more common in people with hair loss, especially women.
"Dr. Yaker and his staff are friendly, welcoming and professional. Everyone greets you with a smile and remembers your name. His offices and procedure rooms are always clean. Dr. Yaker is extremely knowledgable and willing to spend as much time answering questions and discussing options with his patients as they desire. I use Dr. Yaker's hair vitamins and shampoo and conditioner and have definitely seen positive results. So far, I have had two PRP treatments done by Dr. Yaker and he and his staff always take care of me and make me feel comfortable. I have recommended him to many of my friends and family. He's the best!"

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.

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.

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.
Infestation with the mite D. folliculorum which inhabits the eyelashes is well known. Two species are known to inhabit human beings—D. folliculorum and Demodex brevis.[29] It might either be asymptomatic or may cause symptoms of blepharitis. Kemal et al. report an overall prevalence of 27.4% in their study group.[88] Gao et al. have reported a 100% prevalence of the mite when there is cylindrical dandruff.[29] Patients with demodicosis can develop madarosis.[29] 

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.
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.”
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.
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.

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]


That's why I've designed a system I call The Gottfried Protocol, a step-by-step, integrative approach to natural hormone healing that emphasizes lifestyle design first and foremost. It's based on decades of research, my education at Harvard Medical School, my own experiences with hormonal imbalances, my belief in peer-reviewed, well-performed randomized trials to support my recommendations, and what I've learned from patients over the past 20-plus years of practicing medicine. The Gottfried Protocol engages only the top hierarchy of scientific evidence and has been proven in scores of women in my practice.

It’s natural for estrogen levels to fluctuate throughout a woman’s life, but drastic drops can disrupt the hair growth cycle and cause telogen effluvium. For example, during pregnancy, a woman’s estrogen levels are at their peak. Fewer hair follicles enter the telogen stage of the hair cycle, so hair looks thicker than usual. A few months after pregnancy, however, estrogen levels drop and the excess hair falls out. While totally normal, this type of telogen effluvium can be very upsetting for new mothers.
Some medications have side effects that include hair loss. Talk to your doctor if you are experiencing significant hair loss and you think that your medication might be the cause. Your doctor might be able to switch you over to another type of medicine without any reported side effects. Don’t stop taking your medications until you’ve spoken with your doctor, as this could be dangerous for your 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.
Menopause is a natural biological process that all women experience at some point in their lives. During this time, the body goes through numerous physical changes as it adjusts to fluctuating hormone levels. Many women have unpleasant symptoms during menopause, including hot flashes, mood swings, and insomnia. Hair loss is another common occurrence.

Alopecia areata: Researchers believe that this is an autoimmune disease. Autoimmune means the body attacks itself. In this case, the body attacks its own hair. This causes smooth, round patches of hair loss on the scalp and other areas of the body. People with alopecia areata are often in excellent health. Most people see their hair re-grow. Dermatologists treat people with this disorder to help the hair re-grow more quickly. 

The tricky part is that it is believed that the cause of hair loss most likely happened three months prior to beginning to see hair fall out. So, the underlying cause may not be easy to pinpoint. Natural hair re-growth will take time. Just as it can take 3 months after an event to realize that hair is falling out, it can take just as long, or longer, to begin seeing hair re-growth if the cause has been addressed. It is important to be patient! There is hope!
Hi! I'm Kat and I write these posts. I'm obsessed with eyebrows, hair and anything related to fitness. Right now I do microblading, 3d brows and semi-permanent eyebrows in Mesa, Arizona as a certified microblading artist. I'm a licensed cosmetologist and have been for over 10 years as well. I love experimenting with new products and love to share my experiences. Have questions? Leave them below!

In men, finasteride (originally marketed as Proscar) is approved for hair loss associated with androgens. In one study, 62% of women also taking oral contraceptives containing the synthetic progestin drospirenone reported improvement. So it may be effective for female hair loss in the setting of increased androgen. But studies are limited and it is harmful to the male fetus so should not be used by women thinking about becoming pregnant or who are pregnant.

Hypoproteinemia[71] causes loss of hair due to premature onset of telogen. Loss of eyebrow hair has been reported due to chronic zinc deficiency in a patient receiving only parenteral nutrition for 2 months.[26] Acrodermatitis enteropathica is an inherited disorder of zinc deficiency which shows loss of eyebrows and lashes in addition to cutaneous manifestations.[72,73] Biotin deficiency can result in encephalopathy, neurological disorders, skin desquamation, and loss of eyebrows and eyelashes.[74] Iron deficiency may be a possible cause for diffuse telogen hair loss; its exact role however is subject to speculation.[75]
