i think the difference is the length. the mohawk is shave completely on the sides and is a straight row, where as the fauxhawk leaves the sides not as low
i think it looks cool but whatev. some people dont like it. My work is really strict with hair and i want something slightly radical that will go away in a short time. my hair is not long enough to do a gumby or a kanye I'll settle for a fohawk i guess. It's just for lulz
