I have been using Propecia, Minoxidil and Nizoral 2% since 1998. I have gone from being that bald guy to having the most hair out of any of my associates. There is still a bit of receding hairline and I will never be a member of the Beatles but if you ware concerned about hairloss that combo works.
During that time I have done a number of cycles ( Sust/Dec, Sust/EQ, Sust,EQ,Tren etc etc ) and while I am predisposed to baldness I was able to regrow hair.
However let me tell you it is a SLOW process and results take months if not a year or more to be noticeable. A wise man once said if you are concerned about your hair
cut it short
keep fit
dress sharp
