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.

Contrary to popular belief, hair does not grow continuously but actually grows in cycles. It starts at the follicles which are embedded in the skin and the visible part, the shaft, is a consequence of active growth at the follicles over time. The living part of the hair in the skin has blood and nerve supply while the hair shaft is made up of dead cells and protein and does not have a blood or nerve supply. Therefore it can be easily cut without any bleeding or pain.
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]
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).

The recipient sites in the eyebrow can be conveniently made with 20 to 22-gauge needles parallel to the skin, so that hair grows flat on the skin and does not stick out from the face. About 150 hairs are required for a full eyebrow graft. Poddar et al. described good results with a technique of creating recipient tracks with the erbium yttrium aluminium garnet laser.[202]

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]
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. 

Both benign and malignant tumors such as seborrhoeic keratosis, molluscum contagiosum, basal cell carcinoma, squamous-cell carcinoma, sebaceous cell carcinoma, and sclerosing sweat duct carcinoma have been shown to be associated with loss of eyelashes.[1,111–113,119,120] A sebaceous cell carcinoma very often presents as a recurrent chalazion. An associated madarosis (due to lid infiltration and follicle destruction) would help to differentiate the two.[121,122] Tsuji et al. reported a rare case of primary epithelioid hemangioendothelioma of the eyelid associated with madarosis.[123] Primary leiomyoma of the eyelid has been reported with madarosis.[124] Kuan[125] described a case of lacrimal gland tumor masquerading as blepharitis with madarosis.

Sinclair Scale: The 5-point Sinclair Scale is a modified visual grading scale. Grade 1 is normal. This pattern is found in all girls prior to puberty, but in only half of women age 80 or over. Grade 2 shows a widening of the central part. Grade 3 shows a widening of the central part and thinning of the hair on either side of the central part. Grade 4 reveals the emergence of diffuse hair loss over the top of the scalp. Grade 5 indicates advanced hair loss. This grade is uncommon, occurring in less than 1% of women.
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.

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.
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!
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.
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]
