I'd like to take the guys who have thick hair cut to 1/4" long and slap them silly. If they're not going to use it, some of the rest of us would love to have it.
I'm one of those guys. My hair is thick, wavy, and takes a set (not quite as curly as a "jewfro"). If my hair has any length, I can't wear hats, can't put on headphones, can't even take a nap without having to vigorously brush and/or wash my hair to get it to not be smashed down or otherwise unruly. Headphones are a special hell because they leave an apparent dent across the top of my head.
I trim my hair every 2-3 weeks with clippers and a #3 guard. I'd go 1.5 or 2, but the wife and kids don't like it *that* short. Actually, they'd like it longer, but then it starts doing what I described above.
