I started Propecia at the recommendatiion of a hair restoration doctor. It has proved to be a success. My hair has been thicker and has filled in where it was showing more skin. I look much younger because of this. I have had no difficulty with Propecia, though I have heard that it can lower sex drive. I would say "go for it" if you are starting to notice thinning or a bigger "bald spot" on your head.
