I know this sounds like a very silly thread, but hair is just becoming visible on my chin. I like clean looks but I don't really know what to do here. My HS classmates are 2-3 years older than me so I can't really compare myself with them (most of the guys in class shave though). I'm 15 years old and 6"2 in height right now so I guess I'm in post-puberty. Is it too early to shave? Should I trim instead? Are there any biological/social implications to this? I've heard rumors that hair becomes extraordinarily hard after shaving, and hair growth rate increases as well. The Internet is also plagued with bogus and biased information, so I thought I'll post this here. When did you start shaving?
