This kind of guy can pull it off: Almost anyone really. Works great for business types, no-fuss kind of guys.
This kind of guy can’t: Super-creative guys won’t like this (not a whole lot of styling options) and rebellious guys might feel weird looking this mainstream.
The hair you’ll need: Straight hair is a must. Fine or thick will do.
How to style it: You might be able to get away product-free with a cut this short. But for some control, apply a light-hold gel and comb hair to the side.
