Do you have to shave your head every day if you want to do it with a straight? I don't. Even after buzzing it down with Wahl clippers, I have trouble. Head hair is less tough than beard hair, but grows much more densely. I always end up dulling the blade by using too much pressure, nicking my head, and getting a dappled, inconsistent shave where some spots have stubble & some spots don't. Do you head shavers out there shave every day?
