For me, the only real bald spot is at the crown. Otherwise I have diffuse thinning over the top of my head. So I have to shave the whole head.
Yup, I do the whole head. Otherwise the top isn't as smooth as it should be.
ow, crap. I've got a full head of hair which I hate. I've gotta shave it all.
I have alot less on top so it's easier to shave, but it's not gone far enough yet.
