I first noticed minor receding of my hairline at 19. Within a month I began finasteride and Minoxidil. Three months on: tons of shedding. Six months on: even more shedding. I did not give up. Finally, at around the one year two month point, the shedding stopped. The hair that was lost during that shedding period regrew, and my hairloss was dramatically slowed. Today, two and a half years after starting finasteride and Minoxidil, my hair is almost exactly as it was when I first started, and I have experienced zero side effects. Even if you don't see any results by one year: don't give up hope on finasteride. You may just be a late start.
