great !!! Thanks for the info. I totally believe this to be true. My hair transplant Dr said not to worry about this. I didn't believe him. He's just looking to push his drugs to make more money. Is there no hope if you don't take propecia ?? Also, I have been told that donor hair will never die. That can't be true either. Why is it that the healthy hair on the side of your head grows good but as soon as you move it to the top of your head, it dies ??
