That largely depends on the girl and the color of hair. Black hair, blonde, and dark brown, I all think are really pretty in short haircuts/pixie cuts. Meanwhile, red hair I think looks good in just about every way it's possible to wear it. Brown hair I think looks best long and wavy, black hair is nice long and curly, or in a braid/tail of some style. (Twin tailed black hair is gorgeous). Blonde is nice either long and wavy or long and straight, and only on rare occasions does it look curled. Anyways, I could probably be made to change any of my opinions above, but as it stands those are my thoughts on the subject.

I know I'm not a boy but here's what I like:
-on women, I like long hair when it's straight or curly, short hair when it's wavy or curly like black women's hair.
-on men, i like it long on top and short on the sides, preferrably the hair on top is curly.
