Way more convient, liberating, no cost... just everything about having a shaved head is better.
I shave my head with a 0A blade, which cuts down to 1.2 mm. I used to shave it completely bald, but having a little stubble I have found is more comfortable for me. If I was balding, I would totally Bic it completely.
I've been shaving my head for 9 years now, had it shaved for a little while when I was in the Marines, but grew it out for awhile till I went back to college. My girlfriend prefers me with a shaved head, says it fits my personality more, whatever that means. I personally don't care what anyone thinks about it, if you're ugly with a shaved head then... you were ugly with hair too. I mean, I wouldn't want to sleep with someone who only wanted to fuck me for my hair. That would be kind of retarded.
