Propecia review by 36 year old male patient:
My hair loss that I was experiencing stopped completely in it's tracks, and I actually grew back some hair at the crown of my head. Every individual to whom I've recommended the drug has had at least their hair loss stop. I'm a complete cynic and consider this a wonder drug. Once you start taking it (and if you continue to take it for the rest of your life- hey, that's science, man) you will keep all the hair you have from that moment on.
