My hair was thinning and my hairline was receding, so I gave it a shot - the generic stuff is really cheap (like $19-25 US for 3 months), so I thought, what do I have to lose? Holy shit, it flippin' works!! Seriously. I didn't have hair like this when I was in high school. On the box it says it's not supposed to work on receding hairlines, but it exceeded all expectations. I have a nice before/after shot with the same hair length if you're interested.
