Long shiny silky hair is a total pre-requisite. As mentioned, the colour is best natural, no fried-to-death bottle blondes. What about the ol' blonde (natural blonde), brunette and redhead (again, natural) all together? The holy trilogy.

Ah yes, Vino, we need parts in the gal's hair. Side parts, middle parts, and my favourite - parts down the back of her head, with pigtails. Pigtails that can be undone.

Brushing and combing her hair until it's gleaming and ever-so-slightly oily. OMG the smell of hair like that makes me cum in my pants. BTW why doesn't someone make a scratch and sniff card or a perfume that smells like women's hair?

Fingers running through that hair. Stroking the hair with hands, face, lips, cock.

Hair swished against some lucky guy's body.

Personally I'd love to see as much cum in hair as possible. So sexy.
