It seems to me that when women are choosing an alternate hair color from their natural they either dye it blond or black, and on occasion red perhaps. I'm not saying they never choose brown, it's bound to happen, but I can't seem to think of any instances. This leads me to think women may not prefer brown hair on guys either. Come to think of it, I believe Elvis was naturally brown haired but when he became famous he suddenly chose to keep it jet black looking. Would seem to indicate he wasn't too fond of his brown hair, I suppose.
