The hair type we're born with usually naturally suits us the best.
Preferences for hair cuts/styles that suit us usually depend on facial shape, features (especially the eyes, nose and chin), age (laugh lines, etc.), and general build (especially across the shoulders).
It also depends on the person's personality, the preference for high-maintenance vs. low-maintenance styles, etc.
I personally don't like guys with longer wavy hair... I like it short and kinda messy. and don't get dredlocks! they are disgusting. and highlights are OK, as long as you don't have lots and it makes you look gay.. a few blond highlights wouldn't hurt though
