Guys, thank you for all your kind comments on here - it looks like I will do it myself the first time. I would like to mention I am not yet losing my hair! I have been brave and had a number-one cut which feels great, and I now feel an urge to go the whole way and wet-shave my entire head....... That is the way for many here - sly irrespective of mpb. After repeated shavings your skin will toughen. In shaving the big thing for me to remember is to not move the razor sideways - that produces nicks.
