Most Helpful Girl
The kind of haircut where it's shorter on the sides and longer on top? It's often called a Hitler Youth haircut, hahah, although I generally don't like the really extreme ones where it's almost completely bald on the sides. And hair similar to this is usually good: link (holy sh*t, on a side note, this looks scarily like this guy I know/like, from the hair to the sunglasses to the cigarette, damnnn) And I always like sort of tousled hair, and have a weakness for really wavy/curly hair, but obviously you can't control that, hahah.
It depends on the guy though.
