Hi, I'm asking a question for my dad cause he's not too good on computers. His hair has been thinning and he has been losing his hair for about 6 years. It's not too bad. Really just the front sides, about an inch and a half up on each side. He has been on Minoxidil for about three years. At first it worked great. He grew some hairs back and it stopped the hair loss a lot. But the hairs he grew back were very tiny and aren't covering the spots as well as he wants them to. So his doc just put him on Propecia and he started yesterday. He wants to know if he stops the minoxidil will he lose all that hair, or because he is now on propecia will it all stay? Or would it just be good to stick with both? So basically the question is this: Just take Propecia? Or use both Propecia and Minoxidil? Thanks.
