Comparative Study of the Efficacy and Safety of Topical Minoxidil 2% Versus Topical Bimatoprost 0.01% Versus Topical Bimatoprost 0.03% in Treatment of Eyebrow Hypotrichosis: A Randomized Controlled Trial

This randomized controlled trial compared the efficacy and safety of 0.01% and 0.03% bimatoprost gels versus 2% minoxidil gel for treating eyebrow hypotrichosis in 60 subjects aged 18 and older. All three treatments significantly improved the Global Eyebrow Assessment (GEBA) scores (P ≤ 0.001), but no statistically significant differences were found between the groups (P1 = 0.091; P2 = 0.102; P3 = 0.663). The study concluded that bimatoprost, particularly at the 0.03% concentration, is as effective as minoxidil for eyebrow enhancement.
