I use an old electric beard trimmer on 0 setting, bundle/twist up the shrubbery into a handfull bunch and give it a buzz. Then I "hover" over remaining hairs so not to clip the skin. Then off to shower and off the remaining hair with razor cartridge [6 blades!].

I use cordless electric clippers to give myself a haircut. I use the size 000 comb and go allover my head with it, its kinda like crew cut, but I call it an "Alex". Giving myself an "Alex" is having a new haircut
