I am only 20 , have been on propecia since mid january 2004. My hairline wasnt terrible then, although there was thinning there. My crown had considerable thinning. All the signs, my age and early in the hair loss process, pointed to me being a good reactor. However, after about 8 months, my hair has not even slowed down. I even had osme of the sexual side effetcs early on which meant i thoght I would be a responder. Should I quit propecia? Or has anyone in my boat experienced results between 8 months and a year? Thanks for all your help, goo dluck in your own battles with hair loss
