If I want a completely hair free head, I have to shave everyday. But, I shave every other day, sometimes going 3 full days if I'm in a hurry the morning that I would normally shave my head. I'm completely bald by choice because I'm thinning and I have a small bald patch on the crown of my head, so I can go two to three full days and still have it look as though I'm bald by choice. Anymore than that and it's evident that I'm going bald.
I have been shaving my head on a daily basis since early 2005, i prefer being slick bald, i dont feel the same when i start to stubble
