I shaved it last week because I thought it might help my squat to have a bald head. I've heard it can add 50 lbs.... some guys getting as much as a hundred pound carryover if you add the goatee.
Anyway, it grows back real fast, and my squat is down again already. I don't want to be shaving it twice a week so there has to be some better way. Nair or wax are the only two I can think of.
