I'm 23 almost 24, and my beard isn't that great, especially my mustache. I've been taking propecia for a week now, and I've been reading about the effects on facial hair. Does it stop development altogether, or slow it down? I don't want to end up bald and and with a weak beard.. If I stopped, would development continue? I don't have any sides so far, but I'm worried about this! My brother is a year and change older and his beard is much better and thicker.
