Topical Bimatoprost Effect on Androgen Dependent Hair Follicles

Topical Bimatoprost Effect on Androgen Dependent Hair Follicles

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.
