I never expected to shave my head until I started chemotherapy. Rather than be Mr. Patchyhead, I opted to shave my head. I use this unit along with their shaving lotion. My results have been great. I have had a couple of small nicks, but nothing major.You must use a specfic technique with this razor. The weight should be on the back of the razor, not the front. The blade should lightly touch your head while shaving. I find a couple of light passes work best.
