I shaved my head for years with a Norelco electric shaver. I wanted to try using a blade but could not summon the courage to put a blade to the back of my head. One day I bought a HeadBlade and it sat unused for two weeks until I returned it. A week later I grabbed my Gillette SuperSpeed and started shaving my head. Three nicks later I finished. When I felt the back of my head I felt something I never felt there before. It was baby butt smooth. My hand was bloody but the BBS feel had me hooked. Now over a year later I shave with my SuperSpeed with Astra SP's or Personna Lab Blues daily usually nick free. The only time I do nick myself now is with a fresh blade. So when I start a new blade I only use it to shave my face for the first shave.
