I have to agree with Razor here.
I know it sucks when you're young: it started thinning at 18 for me. I used to clip it short for 3 years or so. And that worked, then one evening the comb broke off and it hit my head. Thus I had to do my whole head at 0.5 mm. That was right before going to England with two female friends. I was worried sick, I texted one of them with what happened, and the next day when she saw it her response was: "I can't even imagine you with long hair anymore".
That gave me a huge boost of confidence, that ultimately led to to shaving it after 3-4 times of clipping it to 0.5 mm. I used to feel bad and insecure when people pointed out there were thin/bald spots on my head. "You look bald when the light hits your head". But now that I keep it shaven, I actually feel good when people say: "Damn, Melvin. You're all smooth again!" And I'd just flaunt it. (mostly by calling the ones with hair; hairy hippies that need to shave their head as well"
