You didn't really add enough detail to this question, but I'll do my best to answer. As far as both style and color for hair on guys, it really does depend on what works best for the individual, just like guys might say for girls. Although I do generally like black or brown hair best on guys, that doesn't rule other guys out, because it's just a mild preference. Basically, a guy who looks good with black hair would attract me (visually) and a guy who looks terrible with black hair would turn me off. Make sense?
Like I said, that also goes for the hair style as well. I don't know enough names of different hair styles for men, so I can't really make a general list.
Faux hawks are always hott and work for most anybody, and the don draper look is classic with the side part also very hott, but what always looks good no matter what is a healthy looking and feeling head of hair so invest in a good conditioner and maybe a serum like biosilk I love tht stuff I put it on after conditioning and before styling makes my hair super soft and shiny.
