Hair loss hope? study tests latanoprost acid in women
NCT ID NCT07412587
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether applying a cosmetic ingredient called latanoprost acid to the scalp could improve hair growth in women aged 18-60 with female pattern hair loss or chronic telogen effluvium. Twenty-nine women used one of three strengths of the product daily for six months. The main goal was to see if hair count in a small area increased from the start to the end of the study.
