When I first tried to shave my head - I did it at the sink several years ago with a cheapo disposable razor - I actually cut off a strip of skin about 1/4" wide and 2" long on the back of my head. I didn't use any shaving cream at the time - I just shaved with clippers then wet my head and went to town....it was ugly.
then I scrub the old dome with Jack Black and a Salux Cloth (Japanese washcloth - made out of a coarse nylon - hypoallergenic, dries fast, exfoliates well, and are very inexpensive - just Google them!) - clear away the dead skin and clean out the pores.
