I'd rather have a girl's hair a little dirty. It has their natural sent along with just a hint of their shampoo and conditioner. After playing with it for a while you can feel their oils on your hand. I have three girlfriends. None have real long hair but the one with the longest hair is a little past her shoulders. It's very fine, and she washes it every day. After playing with it during the night, sometimes brushing it and always breathing in it, it's pretty oily by the morning. Lots of of pheromones to breathe in.
