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.
There is also a different in the form of 5AR enzyme (5 alpha reductase) found on the facial hair follicles vs. the scalp hair follicles. This enzyme converts testosterone into that more problematic DHT. Type I DHT is found in sebaceous glands on the face and genital area whereas Type II is found in hair follicles of the scalp. Type II DHT is typically more of a problem in men, but Type II is increased in disorders with high testosterone like PCOS.
Lichen planopilaris and frontal fibrosing alopecia inflammatory conditions, in which the inflammation destroys the hair follicle, can cause a scar or permanent hair loss (usually present as red patches with redness and scale around each hair follicle). In the very advanced stages, they may appear as smooth, bald patches where the hair follicles have been destroyed. Androgenetic hair loss is another non-scarring type. The most common type of hair loss, it is due to the complex interplay of genes, hormones, and age.
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.
Before you start hormone replacement therapy, it's important to talk to your doctor about the possible risks and negative effects versus the benefits of HRT. If you're already at an increased risk for health conditions like heart disease, cancer, and blood clots, HRT may not be the best hair loss treatment for you. If you are prescribed HRT, it important to take the lowest doses that are effective, and to only take the drugs for the shortest amount of time needed to control symptoms.

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!
Giorgos Tsetis: Consumers are lost, and that's the sad part about it. You have a serious problem, you go on the internet and see thousands of products making similar claims, and you can't choose. Most likely, you're going to try the cheapest product with the most compelling claims, realize it doesn't work, and only add further stress. When an industry is not properly regulated, this is the result. Education is such a big component of what we do. Reverse engineering a solution requires a tremendous amount of time and research. What we did was connect all these dots reading hundreds of pages of scientific literature. Education, when it comes to this, is broken into education for the physicians and education for the consumers. It's always hard to educate, because what you're really doing is changing behavior. Slowly but surely, we're actively changing the mindset of physicians and consumers, evolving the way they view and treat hair loss. That is huge, and one of the key reasons Unilever invested in the company. What we did was raise the bar by introducing a new category in the medical channel that remained untapped. That's how we disrupted the market, where now you see hundreds of doctors using Nutrafol as a trusted alternative for men and women. We also have several writers in the company who imagine how we can make this world simple and digestible for people. We want consumers to make smart choices.
According to the International Society of Hair Restoration Surgery, since 2004, the number of female surgical hair restoration patients worldwide increased 24 percent. Modern surgical hair restoration procedures such as Follicular Unit Transplantation (FUT) and Follicular Unit Extraction (FUE) allow surgeons to take hair from the back of the head (genetically permanent hair zone) and transplant it to the areas where balding has occurred. The reason why the hair does not fall out once transplanted in its new location is because those hair follicles take on the same characteristics as the hair in the area where it originated, the genetically permanent zone. Both approaches result in lasting outcomes. In order to know if you are a candidate, Dr. Yaker will go over your medical history and examine your hair and scalp. He will determine if you have ample, good quality hair in the permanent hair zone in order to be able to relocate those hair follicles to the areas of hair loss.
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]
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.
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.

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.
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:
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.

You can even increase your own natural hair growth by eating the right food. Since hair growth depends on what happens inside of your body, it only makes sense that what you eat matters. Foods high in protein are really good for preventing hair loss, since protein is what makes up the hair. Eggs, fatty fish, beef, pork tenderloin, chicken and lentils are all good. Another general rule is to eat many greens and veggies. Kale, spinach, bell peppers, carrots and onion all promote healthy hair growth. Basically, you need to make sure you get all the vitamins and minerals that the body needs to keep producing hair. If you find it hard to get all the important nutrients daily, you can supplement your daily diet with a specialized hair supplement.
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.

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.

Spironolactone is a potassium-sparing diuretic that functions as a competitive aldosterone antagonist and inhibits the interaction of testosterone and DHT with intracellular androgen receptors in target tissues (van Zuuren et al., 2012, Yazdabadi and Sinclair, 2011). Spironolactone also weakly inhibits androgen synthesis (Price, 2003). The anti-androgen effect is more commonly used in hirsutism and acne but has been used successfully at 100- to 200-mg daily doses to treat FPHL (Sinclair et al., 2005). One retrospective study of survey data showed that nearly 75% of women reported stabilization or improvement of their hair loss after treatment with spironolactone (Famenini et al., 2015). Similar results were obtained in an open intervention study from 2005 (Sinclair et al., 2005). While the vast majority of published data discusses adult patients, one case report described the visible improvement of FPHL in a 9-year-old patient after 6 months of therapy (Yazdabadi et al., 2009).
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.
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.
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.
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.
Postmenopausal frontal fibrosing alopecia, a variant of lichen planopilaris, is a distinct form of scarring alopecia which is described in postmenopausal women. It consists of a receding hairline with scarring associated with a partial or complete loss of eyebrows in most affected individuals. The loss of eyebrows may be the presenting sign; however, the hairline reveals evidence of perifollicular erythema on closer observation. Histologic features are identical to that of lichen planopilaris.[42]
The dermatologist also will carefully look at your scalp and hair. During an exam, the dermatologist may pull on your hair. Sometimes a dermatologist needs to pull out a hair to get the necessary evidence. And sometimes a dermatologist needs to look at the hair on the rest of your body to see whether there is too little or too much hair in other areas.
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.

For now, therapies include cortisone injections directly into the bald patches; topical cortisone; Minoxidil — known to many people under the brand name Rogaine; and anthralin cream. A less-widely available option is topical immunotherapy: certain chemicals applied to the scalp can trigger an allergic rash, which alters the immune response, NAAF notes.


Big and bold brows can give great shape to your face. The last thing you want is to see your eyebrow hairs start falling out. Unfortunately, you can experience eyebrow loss just like you experience hair loss. It’s important to understand what is causing your eyebrows to shed so that you can work on stopping the hair loss and promoting hair growth. Here are the most common causes of eyebrow loss.
