About

The purpose of this study is to determine the effect of bimatoprost solution on scalp hair growth. Bimatoprost 0.03% ophthalmic solution is currently approved by the FDA for treatment of glaucoma (Lumigan™) and for thickening of thin eyelashes (Latisse™). Bimatoprost 0.03% is not approved for the treatment of scalp hair loss and its use in this study is considered investigational which means it is still being tested in research studies.

Thirty-three subjects were consented and screened, 9 entered and 9 completed the study.
