Hey Guys, I am 18 and thinking of joined the defense force. The problem is I don't think I will suit a shaved head, I have had long hair almost my whole life and can't imagine what I would look like bald. I have a high forehead and a big head what do I do?
first of all, welcome to SBGs Community!
second: We all look good bald, you just need the guts to try it!
try out a buzzed haircut (#0) and see the look on you. it's not like a shavedhead, but it's preety close!
If you like it, shave it off then! if you do not like it, it'll grow before you'll know

Trying new stuff is good

I hope you'll find the courage.
I'm 20 and I'm BBC! I never imagined I'd look good bald, but being bald changed my life!
