Okay, so tomorrow, my friend wants me to cut his hair into a Colby West-esque mohawk. Ive got the general gist of how to do it, I'm gonna cut all his hair to the length he wants the mohawk to be, but then shave the sides down. Is there anything I should know when doing it? We'll be using a buzzcutter (im not sure what to call it) NOT SCISSORS, that would be a disaster. Any advice?
