my experience
Believe it or not, I swear that my hair thins a little when i'm on, but a couple of months later it looks thicker. It has been like that the past two times.
the lady at the hair place said to use this shampoo called "nioxin" if my hair thins out. I think it is spelled right. it only works on some people like rogain. My brother-in-law has been on it for three months, worked for him, but not another friend of mine. I know I will try it when the time comes.
