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).
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!
These important micronutrients, which are all essential for hair health, are part of my Balance Supplements. And even if you eat a healthy, phytonutrient rich diet, you might not have optimal levels of the vitamins and minerals you need to promote hair health. Environmental factors beyond our control, from the mineral-depleted soil in which most of our food is now grown to shifts in growing practices that have reduced the amount of vitamins and minerals in various foods, can leave us eating a picture-perfect diet and still deficient in certain micronutrients.
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.

Not only that, but plucking, waxing, or threading can also lead to permanent eyebrow loss, ingrown hairs, and infections. With repeated trauma to the hair follicle, your follicle can become damaged and scarred. If this occurs, your hair may never grow back again. Make sure to be extra careful to only pull out the hairs that you want to remove when you are plucking your brows. You should also wash your tweezers with alcohol before you start plucking or seek treatment at a reputable salon to prevent infections.

Toxic alopecia occurs when there is a disruption of hair growth in the anagen phase. This usually occurs following chemotherapy and radiotherapy.[94] Radiotherapy for various types of ocular tumors, eyelid and choroidal tumors have been reported to produce madarosis.[95–97] Hair loss due to radiation is usually reversible, but may be permanent when the dose of radiation is in the range of 50 to 60 Gy.[94]

Female pattern hair loss is the most common cause of hair loss in women and one of the most common problems seen by dermatologists. This hair loss is a nonscarring alopecia in which loss occurs on the vertex scalp, generally sparing the frontal hairline. Hair loss can have significant psychosocial effects on patients, and treatment can be long and difficult. The influence of hormones on the pathogenesis of female pattern hair loss is not entirely known. The purpose of this paper is to review physiology and potential hormonal mechanisms for the pathogenesis of female pattern hair loss. We also discuss the current hormonal and hormone-modifying therapies that are available to providers as they partner with patients to treat this frustrating issue.
But, interestingly — and what most people don't initially realize — is that eyebrow hair loss is often a sign of an internal disease. The classic example of this is an under-active or over-active thyroid. Loss of the outer third of the eyebrow, in particular, is a characteristic sign of an under-active thyroid. Fortunately, thyroid conditions are easily treatable, usually with oral medications, but the medications generally have to be taken for life. The eyebrows should grow back, but there is always the possibility that they may not. The thyroid gland plays a huge role in our bodies, so it is important to have any thyroid issues treated. 

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.

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.
If, however, you aren’t so sure that any of the causes listed above are a problem for you, then a good place to start may be to talk with your healthcare provider about testing. It is important to learn the root cause – especially if dealing with infertility – because that which is causing hair thinning and shedding may also be contributing to your inability to conceive.
Trichotillomania is a hair pulling disorder associated with anxiety, stress, depression, boredom and frustration. It is where a person manually removes hairs with their finger, either a few strands throughout the day or sometimes many strands at one time during an emotional outburst. This behavior is usually a means of coping with stress or emotional turmoil. However, it can sometimes become a habit that is difficult to break. The eyebrows is a commonly targeted area as is the scalp. 

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.

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.

Eventually this can lead to loss of the hair in the infected follicle.

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]

There is some evidence of a link between baldness and prostate cancer and other diseases. Harvard Medical School reports that men with vertex baldness have 1.5 times more of a risk of developing prostate cancer than men without bald spots. The risk of coronary artery disease is also more than 23 percent higher in men with vertex bald spots. Investigations are ongoing as to whether there is a link between DHT levels and metabolic syndrome, diabetes, and other health conditions.
Monitor any hair loss when starting new medications. Numerous medications can cause temporary or permanent hair loss, including chemotherapy,[28] antidepressants, and mood stabilizers.[29] Nonetheless, many other medications can cause hair loss in isolated cases. If you've noticed hair loss after starting a new medication, talk to your doctor about this side effect.
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.

Eight of 69 eyes receiving intra-arterial chemotherapy with melphalan for retinoblastoma were found to develop a cutaneous periocular erythema with partial loss of eyelashes.[110] Gobin et al. also reported a 12.6% incidence of madarosis following intra-arterial chemotherapy for retinoblastoma.[111] Moti and Fausel described a case of cyclical alopecia areata including the eyebrows and eyelashes after treatment with paclitaxel and carboplatin.[112] Other drugs which have been implicated in hair loss due to anagen effluvium are adriamycin, cyclophosphamide, daunorubicin, epirubicin, etoposide, ifosfamide, irinotecan, topotecan, vindesine, and vinorelbine.[98,113]

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.


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.
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]
