Bimatoprost Can Increase Growth and Density of Eyebrow Hair: A Prospective Study on a Group of Young Women

The study on 27 young women over 10 weeks found that bimatoprost significantly improved eyebrow density (70% vs. 30%; p = 0.003) and hair elongation (59% vs. 26%; p = 0.014) compared to sweet almond oil, with higher satisfaction rates (66% vs. 22%; p < 0.001). Adverse events were minor and resolved spontaneously. The study concludes that bimatoprost is effective and safe for enhancing eyebrow growth, but larger studies are needed for further validation.
