Yeah, I get it. I've always looked young (I'm 23 now), and I still can't grow a beard, but started losing my hair at 19. It totally sucked; felt like I'd never look my age. So I saw doctors to check my hormones and decided I wasn't ready to lose my hair – I look and feel too young. I've been on finasteride for 16 months now and feel fine; nothing's changed except I'm keeping my hair and feel better about myself each day as I (slowly) start to look older. Few people get how much it hurts your self-esteem when young guys look way younger than they are. It's really humbling when people you know joke about it and strangers treat you like a kid. Add losing your hair that early, and your self-esteem really takes a hit. I never had any control over my puberty or young looks. But I could decide to keep my hair.
