This article is taken from on of the most prestegeous journals in dermatology.  Every medication has its risks. Hypertrichosis (excess body hair) is a common side effect in the study population making it difficult for a permanent solution for women who experience this side effect. My wife was on minoxidil topically and enough was absorbed into her body to produce early facial hair. It went away after she stopped it.  For men, more body and facial hair may not be a problem, so this is a real alternative for those who can’t take finasteride.
