I've been shaving my head for years. I used to use a Gillette Track III but with the infection risk during treatment I bought a good quality electric and have been using it ever since. The hair follicles in the radiation field died and fell out. The hair loss from chemo was fairly minimal and it grew back back. No matter I still shave it. Maybe you could benefit from waxing but have them use the hard wax (like bikini wax) and not the sticky pine tar stuff.
