Topical Finasteride

Hair Restoration Options:

In 2018, Lee et al. reviewed 7 studies that looked at the use of topical finasteride for the treatment of pattern hair loss in men and women. He looked at several concentrations, including finasteride 0.005%, 0.25%, and 1%. The good news is that they all showed some efficacy with limited systemic effects. Overall, topical 0.25% finasteride solution applied once a day seemed to be the most effective. The downside is that topical finasteride did cause some scalp irritation in some participants, which could be a limiting factor for some patients. It is not clear if the irritation came from the finasteride itself or from one of the other components in the solution.
