The term superciliary madarosis is often used describe abnormal eyebrows and eyelash hair loss which can be partial or total. Depending on the cause, the can be weird since besides the hair breaking and falling out easily, some people may end up with a part, half, inner, outer third or one on or both eyebrow missing. In fact,  thinning at ends is common. 

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.


Exercise is a key component of a healthy lifestyle. You’ll feel stronger and happier once you incorporate exercise into your daily routine. It also helps prevent some of the other symptoms of menopause, including mood swings, weight gain, and insomnia. All of these factors are important for maintaining hormonal balance, which promotes healthy hair growth.

To prove the fact that this does not happen on your scalp alone, Everyday Health notes, “too much thyroid hormone, the hair on your head can become fine, with thinning hair all over the scalp. When there is too little of this hormone, there can be hair loss, not just on the scalp, but also anywhere on the body”. This proves patients with underactive thyroid (low thyroid) can have their eyelashes and eyebrows falling off.
There are numerous nonsurgical treatments that when combined, can offer significant hair improvements. Dr. Yaker’s TCHR Volumizing Glycolic Acid Shampoo and Conditioner help restore vitality to the hair by deep cleaning the scalp and reestablishing lost moisture content and physiological pH to the scalp and hair. Dr. Yaker has also formulated his own oral supplement, which is a blend of Aminoplex hair repair vitamins. This is made up of amino acids (building blocks of protein) that produce keratin, which makes up close to 97% of our hair. In addition, Dr. Yaker’s specially compounded FDA approved topical medication, Minoxidil (brand name: Rogaine®), is clinically proven to help slow down, stop and even reverse hair loss in women. Other nonsurgical therapies offered are Low Level Laser Therapy (LLLT) using the advanced LaserCap®, and Platelet Rich Plasma (PRP) with placenta-derived extracellular matrix therapy to help restore thinning hair. Lastly, Dr. Yaker offers scalp and facial micropigmentation where permanent ink is applied to the skin, creating micro dots that replicate the natural appearance of hair. This is used for the scalp and eyebrows.

Thallium poisoning should be suspected in any patient manifesting nervous system and gastrointestinal symptoms along with alopecia. The hair loss affects the scalp, periocular hair, limbs, and sometimes the axillae. Examination of the hair roots under a microscope using polarized light shows distorted anagen roots and several black zones in continued poisoning.[118]
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.
The first step in treatment is to identify the cause of the hair loss. Then, treat it appropriately. If an internal cause is the culprit, it should be addressed — for example, thyroid medication for thyroid disease or supplements for a nutritional deficiency. External skin conditions are often treated with topical medications, and, once treated, the hair loss usually recovers. I often recommend Latisse as an adjunctive treatment. Though frequently associated with eyelash lengthening, it is a great option for thickening brows. In fact, people with brows that thin with aging (I typically don't see this in women under 50) may want to opt for Latisse.
There’s no doubt that estrogen and hair loss are connected, but there are certain factors that determine how much of an effect estrogen levels have on your hair. As one of the main visible measures of your health, hair growth is often one of the first areas affected when hormones are off-balance. Let’s take a look at the links between estrogen hormonal imbalance and hair loss.

After giving birth, reaching menopause years or experiencing other hormonal imbalances, it’s not uncommon for women to start losing hair. And while hair loss is a normal process (the American Academy of Dermatology estimates the average person sheds about 50-100 hairs a day), it’s also something that can be remedied by addressing underlying health and hormonal problems.
Dr. Kimberly Langdon Cull is a University-trained Obstetrician/Gynecologist with 19-years of clinical experience. She delivered over 2000 babies and specializes in gynecologic diseases such as menstrual disorders, infertility diagnosis and treatment especially pertaining to tubal blockage and polycystic ovarian syndrome (PCOS). Dr. Langdon is the inventor of 6 patent pending medical devices, and attended Ohio State University from 1987-1995 receiving her Medical Doctorate Degree (M.D.) with Honors in Obstetrics and Gynecology.
Protein: When the body does not get enough protein, it rations the protein it does get. One way the body can ration protein is to shut down hair growth. About 2 to 3 months after a person does not eat enough protein, you can see the hair loss. Eating more protein will stop the hair loss. Meats, eggs, and fish are good sources of protein. Vegetarians can get more protein by adding nuts, seeds, and beans to their diet.
Dutasteride is a 5-alpha-reductase inhibitor that binds both types I and II enzymes. Compared with finasteride, its inhibition of type II enzymes is three times more potent; its inhibition of type I enzymes is 100 times more potent (Clark et al., 2004). Dutasteride is not approved for the treatment of FPHL by the FDA, and ongoing studies on the efficacy of the inhibitor are promising but largely focus on male patients (Gupta and Charrette, 2014, Olsen et al., 2006). A study of women after 3 years of therapy showed that dutasteride may be more effective than finasteride in women under 50 years of age as measured by hair thickness (not hair density) at the center and vertex scalp (Boersma et al., 2014). One case report of a 46-year-old female with FPHL showed some response after 6 months of treatment with a dose of 0.5-mg dutasteride daily despite a minimal response to treatment with finasteride and minoxidil (Olszewska and Rudnicka, 2005). Data with regard to the treatment side effects in women is extremely limited. Dutasteride is classified as pregnancy category X because of teratogenicity and should have the same theoretical risk of breast cancer as mentioned in relation to finasteride (Kelly et al., 2016).

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]
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.

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.

The real culprit appears to be dihydrotestosterone (DHT), a more potent form of testosterone. DHT is made from testosterone by a specific enzyme in the body, and while both testosterone and DHT are known to have a weakening effect on hair follicles, there appears to be something unique about the conversion process of testosterone to DHT that relates to thinning hair. This is why some drugs that are marketed for hair loss block the conversion of testosterone to DHT. (It’s important to note, however, that these drugs tend to be less effective in women than men, and that one of them—finasteride—is only approved for hormonal hair loss in men, not women. What’s more, the drug has been associated with increased risk of sexual side effects, depression, nausea, hot flashes, and increased estrogen levels—and too much estrogen is its own risk factor for thinning hair; more on that below.)

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.

Hormones don’t just affect your mood, they are also common culprits of hair loss. A hormone imbalance caused by thyroid disease, pregnancy, menopause, or hormone medication (like birth control pills) can lead to eyebrow loss. Thankfully, once you identify the source of the hormone imbalance and address the problem, your hair will likely grow back naturally.


Skin infections can cause hair loss at the affected area. One of the more common causes is a fungal infection of the skin, also sometimes referred to as a ringworm. Eyebrow fungus is more likely to be related to a scalp fungus (tinea capitis) and both areas are often affected at the same time. A bacterial infection is another possible cause. Folliculitis for example is a condition where the hair follicle becomes infected usually with bacteria like Staphylococcus aureus. Eventually this can lead to loss of the hair in the infected follicle.
Liver support: is necessary to eliminate unneeded wastes from the body. Everything we take in is processed through the liver and toxins are broken down into water soluble byproducts so they can be moved into the intestine and pulled into the stool for elimination. Foods like cruciferous vegetables (kale, broccoli, collard greens) and lemon support the liver detox pathways. Herbs like milk thistle, dandelion root, and burdock root help to support  liver cleansing.

Growth on Eyebrows – Some common growths on brow aresa such as warts or any unusual growth could hamper eyebrow growth. Skin growth cause a thick barrier that is shell like and it will make it impossible for eyebrows to penetrate them thus you will not have regrowth. Some of the common growths include moles, hemangiomas, seborrheic keratosis among many others.
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.
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..

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.
FPHL or androgenetic alopecia is the most common cause of hair loss in women and one of the most common chronic problems seen by dermatologists worldwide (Varothai and Bergfeld, 2014). FPHL is a nonscarring form of alopecia in which the frontal hairline is maintained, but there is progressive hair thinning at the vertex of the scalp. Thinning of the hair is secondary to alteration of the hair cycle with shortening of the anagen phase and simultaneous lengthening of telogen. This increase in the resting phase and decrease in the growth phase of the hair cycle results in the miniaturization of hair because long terminal hairs are gradually replaced by short vellus hairs (Messenger and Sinclair, 2006, Sinclair et al., 2011).
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.

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.


The process takes about two hours to complete, but you’ll need to go in for a touch up about once a year after the initial appointment (and possibly a second follow-up). Microblading costs between $500 and $1,000, and the results should last for one to three years. Your natural brow hair will continue to grow, but you likely won’t need to get waxed as often. “Most people find their regular maintenance decreased because they have the shape they want after microblading,” Studabaker says.
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!
The photo included here shows an example of one condition which could affect the eyebrows, eyelashes, facial hair and pubic hair. This is a type of thinning hair found in women that are regularly seen at Sussex Trichology in West Sussex. These symptoms obviously cause the sufferer much distress as the appearance has dramatically altered the hairline since the eyebrows define the face. Shuna Hammocks, our Consultant Trichologist, is able to diagnose your condition and discuss it at length and then design a treatment plan for you. It may be suggested that you attend the clinic for hair treatments which involve a combination of creams, steam and massage.
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.”

It is known that during pregnancy, because of an increased level of estrogen, there is a tremendous growth of new hair. However, during menopause it is noticeable that the reduced level of estrogen hormone tends to cause hair loss. When the estrogen hormone levels tend to drop, the hair follicles fall under the influence of the male sex hormone or the testosterone, which cause the shortening of the growth phase of hair. Subsequently there is a noticeable hair loss. This hair loss caused due to the drop down of estrogen levels may cause patchy hair loss or complete baldness.
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.
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.
Hormone Replacement Therapy: You may be advised to go for hormone replacement therapy or may take supplementary estrogen in case your doctor suspects that the hair loss is caused because of low or lack of estrogen hormone. These supplements may either be taken orally or may be applied topically to the skin as a gel. However it must be mentioned that not all women are benefited with this type of treatment for low estrogen levels causing hair loss.

According to the new study, British scientists say they found over 200 genetic markers linked to hair loss. More specifically, the study focuses on male pattern baldness. This type of baldness, also known as male alopecia, is the most common form of hair loss in men. Researchers believe this affects as many as 30 to 50% of men by the time they reach the age of 50.
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.
Take extra care in looking after your hair. Use a gentle, nourishing shampoo (we love Bumble and Bumble Gentle Shampoo) to promote good condition and prevent breakage. Try using a silk or satin pillowcase. Avoid harsh styling products and techniques that apply heat to the hair (blow drying, curling irons etc) as these can cause more damage to fragile hair.

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.
THE TREATMENTS If no trigger is present, it’s likely you have androgenetic alopecia, a hereditary condition that causes the hair follicles to get progressively thinner over the years. The most effective topical medication for the condition is minoxidil (brand name Rogaine), the only treatment for hair loss in women that has been approved by the Food and Drug Administration.
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.
Dutasteride is a 5-alpha-reductase inhibitor that binds both types I and II enzymes. Compared with finasteride, its inhibition of type II enzymes is three times more potent; its inhibition of type I enzymes is 100 times more potent (Clark et al., 2004).

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.

Seborrheic dermatitis is a condition where you have itchiness in the eyebrows.. like serious, serious itchiness. First of all, if you think you have this: see a derm, stat. You need a derm to confirm (can I trademark that saying?), and you definitely need a derm for the prescription. A dermatologist will tell you to treat the seborrheic dermatitis with a combination of desonide cream and ketoconazole cream twice daily for one week. Or, they may tell you to use a ketoconazole shampoo to control the problem.
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.
Minoxidil: This medicine is applied to the scalp. It can stop hairs from getting thinner and stimulate hair growth on the top of the scalp. The U.S. Food and Drug Administration (FDA) has approved minoxidil to treat hair loss. It is the only hair re-growth product approved for men and women. A dermatologist may combine minoxidil with another treatment.
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.
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.
A number of skin and hair disorders can lead to eyebrow hair loss and sometimes it may be linked to systemic diseases like lupus. Specific skin and hair disorders that are most likely to lead to eyebrow thinning and hair loss have been discussed below but other conditions like psoriasis may also be involved if it occurs on the eyebrow or forehead. Eyebrow hair loss may occur in people on chemotherapy (cancer medication) and with radiation therapy to the head.
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.
