does propecia really work to regrow hair?

I have seen it at work. If you are a relatively young male suffering from male pattern baldness or thinning hair it just may work for you. I know though that you need to be careful and have liver tests done occasionally as it affects your liver. Talk to your doctor, can't hurt to try.

my friend's older brother started taking it when he started going bald in college. Six years later he still has a full head of hair

"In the longest reported controlled clinical study of men with certain types of male pattern hair loss, 2 out of 3 men on PROPECIA [Finasteride] regrew hair, as measured by actual hair counts over time. Whereas all men in the study taking a placebo (not PROPECIA) lost hair."
