I started using Rogaine about 3-4 months ago... It definately stops/really slows down the process of your hair falling out. It's a little bit of a pain to put it on and wait for it to dry up, also causes some irritation on your scalp with it. My dermatologist said Rogaine more or less is great for stopping hair loss, not really effective for regrowing hair. I just started using Propecia about a month ago. There's a lot of rave reviews about Propecia. There's a new drug that is coming out for hair loss, some what of a stronger Propecia, it's called Dutasteride. It's been approved by the FDA last year I read. It's due to come out sometime in the very near future. At first I thought my hair was falling out cause of all the gel and styling products I put in my hair, but my dermatologist told me, hair loss only happens for hereditary hair loss. That it didn't matter how much gel or anything you put. He says it's a common myth.
