I like natural, uncolored virgin hair.... You naturally have lots of colors in your hair, and I love it when you see someone's hair in the sun and it's red and brown and blonde and everything.... I just don't think it's as cool when it's colored.
Brown and/or black is my preference... however, I don't discriminate. Hmm, I did see a girl yesterday though who had BEAUTIFUL red hair. I guess they're all good.
I don't think it matters. I used to be really attracted to blondes then brown. Some men with gray hair are extremely handsome. Just look at Olhippie. He is charming. I have even seen some men that are bald who are really attractive. I don't have a preference.
black or unnaturally firey red. too bad red dye is so fucking hard to keep in your hair or i'd still have mine flourescent.
