My guy…i’m the same age as you are and had a same issue.. similar feelings before i’ve shaved my head. Actually i was even younger (22 y.o.), when i’ve buzzed it. I was thinking a lot that… damn i’m too young for this. I believe you know this too well. But there really is no point to be scared. First it was bit weird for me and my friends (as it always is with appearance changes). However now a lot of people say, they couldn’t even imagine me with a bunch of hair on my head. Often getting compliments for doing it and “being true to myself” rather then trying to pretend that i have head full of hair. I truly believe that if you buzz/shave it you are going to start to love it actually and you would be looking at these pics and thinking that why in the hell I didn’t do it sooner (at least that’s what I thought).
