I use .25 because i'm only 19 and figure I could still grow more, it's too early to eliminate dht from my body. plus, i have read that you can still get good results from .25 or .5 without the sides, so thought i would try this first.
I haven't had any major sheds, but i usually lose at least 10 hairs every shower. I have been on it for three months now and the tingling itchy feeling on the scalp has started again in the past 2 or three weeks. It hadn't happened since before i was on propecia. The hair loss seems to have increased too. I thought the shed was supposed to be right when you started propecia. At the 3 month mark it seems like i'm losing more hair than before.
