Eyebrow loss may have substantial negative functional and social consequences. Evaluate the safety and efficacy of bimatoprost 0.03% in subjects with eyebrow hypotrichosis. This multicenter, double-masked study randomized adult females or males with eyebrow hypotrichosis to receive bimatoprost 0.03% twice (BID) or once daily (QD) or vehicle BID for 7 months. Primary endpoint was overall eyebrow fullness at Month 7. Secondary endpoints included eyebrow fullness (mm), darkness (intensity units), and subject satisfaction with treatment. Safety was also assessed. At Month 7, the proportion of subjects with improvement was significantly higher in bimatoprost groups versus vehicle (both, p < .001). Improvements occurred in both bimatoprost groups versus vehicle after Month 1 and continued through follow-up; eyebrow fullness and darkness improved as early as Months 2 and 1, respectively (both, p < .001). Greater satisfaction was reported with bimatoprost versus vehicle at Month 2 and...
