Topical Treatment of Eyebrow Hypotrichosis with Bimatoprost 0.03% Solution: Case Report and Literature Review.

The eyebrows frame the upper margin of the orbit and are an essential feature of the facial landscape. Eyebrow hypotrichosis, also known as madarosis, is characterized by a lack of growth or loss of eyebrow hair. Eyebrow loss can have cosmetic, functional, and social consequences. Eyebrow hypotrichosis can be idiopathic or related to an underlying condition. Bimatoprost 0.03% solution is a prostamide F2α analog indicated for the treatment of glaucoma and ocular hypertension that has also demonstrated efficacy for hair growth; indeed, it is currently approved by the Food and Drug Administration for the treatment of eyelash hypotrichosis. A 60-year-old woman with eyebrow hypotrichosis is described who achieved excellent and sustained growth of her eyebrows with continual daily application of bimatoprost 0.03% solution. We discuss the therapeutic mechanisms of bimatoprost 0.03% solution in hair growth, review other potential modalities for treating eyebrow hypotrichosis, and summarize the findings of investigators who have utilized bimatoprost in the treatment of eyebrow hypotrichosis.
