I have been using Andis T-Outliners, which are electric liners to cut/shave my head. Previous to this I went through a few different electric shavers that didn't give me as close of a shave as I liked. I have used the Mach 3 before that, between that, and sometimes here recently. But I always get bad irritation on the back of my neck and head. I am not sure if it is because I have thick coarse hair or what. I have been told that could be the cause, I also have been told it could be because of the number of blades I used.
I would love to be able to use a razor because it gives such a phenomenal shave. But, the irritation isn't something I can get used to. Any advice on a razor I should use, single blade cartridge, double edge safety, 3/4/5 blade cartridge? Or would my best bet be to stick to my outliners?
