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. 

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..
Contact dermatitis causes skin inflammation and when severe it can affect the hair follicles as well. It can either be due to some irritant making contact with the skin of the eyebrows or due to a substance to which a person has an allergy. This gives rise to the two types of contact dermatitis – irritant contact dermatitis or allergic contact dermatitis. Substances that could cause contact dermatitis at the eyebrow includes eye makeup including eyebrow pencils, hair removal creams and waxes, other cosmetics, hair dyes and scalp hair styling products.
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. 

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.
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. 
See the doctor for sudden hair loss. If you suddenly lose your eyebrows, that could be a sign of a more serious problem, particularly if you only lose your eyebrows or eyelashes and not other hair. Sudden loss of eyebrows can be a symptom of eye conditions, skin conditions, systematic disorders, infections, and nutritional deficiencies. Seeing your doctor can help you narrow down the condition.[30]
Certainly when those testosterone levels rise, DHT is even more of a problem. DHT levels can be elevated and be within what doctors consider "normal range" on a blood test, but they may be 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 regular levels of chemicals, including hormones.
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.
Giorgos Tsetis: I am an entrepreneur and have an engineering background that allows me to think in strategic ways to solve complex problems. Of course, I did have this very personal experience. But, to be honest with you, getting into this category wasn't directly a choice, it felt more like destiny. I say that, because their are literally millions who suffer from what I was suffering from. Aside from being a model, I owned an engineering company in New York, and business was steadily growing. The tipping point came when I found out the University of Washington published research that said my issue could cause permanent sexual dysfunction without the specific drug I was taking. That's when I panicked, reached out to my business partner and dear friend, and we begun to dig deeper into the issue. As we started diving deep, we recognized there was a tremendous white space.

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.


Other important vitamins for eyebrow hair growth to consider include vitamin B complex especially vitamin B-12, B-7 (biotin), can ensure healthy hair and skin. In addition, vitamin D can help in hair growth by creating new pore and thus a possibility of more hair (see more on Stem Cells Translational Medicine. Finally ensure you have zinc, enough protein, and omega 3 fatty acids.
It is important to understand the phases of hair growth which play an important role when in further understanding some of the causes of hair loss. During the active phase known as anagen the cells multiply at the follicle and push out to form the shaft. It is followed by a transitional phase known as catagen where the outer layer of the hair shrinks and it becomes attached to the root. Thereafter there is a resting phase known as telogen where there is no growth or changes in the hair.
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]
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.

Eating too many high-glycemic foods for too long (often in combination with other lifestyle factors, like being sedentary and experiencing chronic, unremitting stress) can cause an overload of insulin in the body—and too much insulin disrupts ovulation and signals the ovaries to make testosterone. More testosterone predisposes the body to more DHT conversion, and, hence, more hair loss.

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.
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.
There are numerous diseases that can affect the hair and scalp. Hair loss can be caused by a variety of conditions. Diseases such as alopecia areata, anemia, male/female pattern baldness, and infections of the scalp can all cause significant difficulty and loss of daily well-being. Stanford Dermatology has established a special clinic focusing on the diagnosis and treatment of these disorders of the hair.

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).

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.
Mistakenly thought to be an exclusively male disease, women make up a significant percentage of hair loss sufferers all around the world. Forty percent of women have visible hair loss by the time they are age 40. After menopause, that number increases even more. Hair loss in women can be absolutely devastating for self-confidence, self-image and emotional well-being. Although it is not a life threatening disease and sometimes underestimated by physicians, hair loss can take an emotional toll that directly affects physical health. Hair is an important part of woman’s face and beauty, therefore it is not easy for any woman to face changes that affect the quality and especially the quantity of her hair. Hair loss in women is a serious life-altering condition that shouldn’t be ignored and has to be diagnosed and treated in the best possible way.

The first thing you'd want to try is to talk to your doctor about stopping the medicine -- ask if there's a substitute. If you can't find a substitute for the medication and you must take it, then you could consider filling in your eyebrows. You can find brow products at any local drugstore. YouTube has many, MANY brow tutorials you could learn from.
Anagen effluvium occurs after any insult to the hair follicle that impairs its mitotic or metabolic activity. This hair loss is commonly associated with chemotherapy. Since chemotherapy targets your body’s rapidly dividing cancer cells, your body’s other rapidly dividing cells such as hair follicles in the growing (anagen) phase, are also greatly affected. Soon after chemotherapy begins approximately 90 percent or more of the hairs can fall out while still in the anagen phase.

Testosterone converts to DHT with the aid of the enzyme Type II 5-alpha reductase, which is held in a hair follicle's oil glands. Scientists now believe that it's not the amount of circulating testosterone that's the problem but the level of DHT binding to receptors in scalp follicles. DHT shrinks hair follicles, making it impossible for healthy hair to survive.

Topical estrogen and progesterone creams and oral medications are generally the forms prescribed for post-menopausal women with androgenetic alopecia. But HRT will rarely, if ever, be prescribed for treatment of hair loss alone.] If you have other bothersome symptoms which might warrant HRT, in addition to hair loss, you'll first need to undergo a thorough gynecologic and physical exam, and will likely have blood tests done to measure hormone levels before these drugs are prescribed.

During pregnancy, high concentration of estrogen levels in women result in the development of thicker, stronger, longer and healthier looking hair. Following pregnancy however, women tend to fret and think that they’re losing their hair when in fact they’re merely shedding the excess hair that the excess oestrogen created. The hair that was in a prolonged anagen stage are now all shifting into telogen (resting phase) to make way for new hair growth. This type of hair loss is comes under the condition known as telogen effluvium but the good news is that when oestrogen levels have returned to normal, your hair will too.
Other conditions, which can cause eyebrow hair loss, include infection by a number of fungal infection, which are common, both on your scalp and eyebrow areas, affliction by pests such as lice, which will cause itching, and scratching. Infiltrating disorders such as scars, alopecia mucinosis, and sclerosing disorder could also cause brow hair loss. If you are heavily using any of the following drugs, they could also cause eyebrow hair loss:
Ever since Cara Delevingne set the trend for thick eyebrows (although women on the eastern side of the Prime Meridian have been keeping their eyebrows luscious and strong since the dawn of time), the quest to keep your eyebrow hair supremely groomed and in shape has become the primary beauty concern of all women. So now that eyebrows have come into the razor sharp focus of beauty standards that women (again) need to adhere to, it can come as quite a shock for some when they start losing their eyebrow hair. One day you’re lovingly brushing out your thick luscious eyebrows and the next moment you find yourself desperately filling them in with every eyebrow pencil you can get your hands on. You’re confused. You’re anxious. You don’t know what’s going on. And you’re trying out every random hack that the internet spews at you to stop losing your eyebrow hair. Lady, you need to calm down for a second. First, figure out why you’re losing your eyebrow hair in the first place. Let’s look at a few possible causes of your eyebrow hair loss.

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.

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]

Blow dryers, flat irons, and other devices: Frequent use of a blow dryer tends to damage hair. The high heat from a blow dryer can boil the water in the hair shaft leaving the hair brittle and prone to breakage. Dermatologists recommend that you allow your hair to air dry. Then style your hair when it is dry. Dermatologists also recommend limiting the use of flat irons (these straighten hair by using high heat) and curling irons.
When you see more hair in the shower drain, in your hair brush or your ponytail holder goes around an extra time all of a sudden this is typically low thyroid, high stress or low estrogen. It can also be the increased inflammation or oxidative stress or as a result of nutrient deficiencies especially anemias (low iron, B12, etc.). Let’s dig into each of these.
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]

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. Cotsarelis warns men taking both Propecia and testosterone replacement to make sure their doctor carefully monitors their testosterone levels.
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.
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. 

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.
In extreme cases, such as disordered eating and anemia, an iron deficiency may be to blame for thinning brows. “Even if you don’t have anemia, and you have low levels of stored iron, that could contribute to hair loss,” says Rajani Katta, M.D., a dermatologist and clinical assistant professor of medicine at Baylor College of Medicine, who studies the link between nutrition and hair loss. Iron is found in meat, fish, and other animal products, plus beans and legumes, so vegans and vegetarians might be more likely to be low in iron. Your derm can do a ferritin blood test to check your iron levels. But don’t start an iron supplement without medical recommendation. Too much iron can also have negative effects, says Dr. Katta.
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]
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.
