I don't believe in scrambling around like an insecure phaggott when your hair starts to fall out. It happens to almost every guy at some point. Let it be what it is. Why hemorrhage money and sacrifice your ability to get a hard-on just to hang on to a few thin-ass hairs on your head. Be a boss, shave your head and say who gives a fuck. Control what you can control, don't be a bitch. You are fighting a losing battle anyway.
