I would in a heart beat. I love men with long hair. Love it. The exception being relaxed hair. I don't like relaxed hair on men. Or pressed and curled. Or flat ironed. Or permed. Basically, I don't find men in rollers the sexiness. And if he has dreds, they have to be neat.
I don't care what type it is as long as it's clean and not thin/fine. I'll take 1a to 4z. He can be neosoul, corporate, biker, whatever.
I will say that if this guy expects me to cornrow his hair, he is sadly mistaken. I can't do anything more complicated then flat twists and regular plaits.
