So I first shaved my head almost 2 years ago and kept it for about 3 weeks. Then shaved it again back in October 2011 and kept it about 3 weeks. Then Shaved it again at the end of December 2011 and kept it for 4 1/2 weeks. Then shaved again a week ago. Finding myself coming back to the sly look more often then I thought I would when I tried BBC. Not sure what it is that keeps bringing me back to the sly look, but I definatly enjoy it.
