I'm not sure if you mean having two hair-whorls (swirls) in the head, referring to hair growth directions in the human head. If yes, then a person with two hair-whorls is usually deemed to be a bit stubborn and willful. I know, cause I have three. Originally, hair whorls are associated with how animals (e.g. horses) behave. The beduoins of Arabia and gypsies in olden times believe in the theory that those horses with two whorls are more of complicated nature or temperamental. I think this is where the theory on human hair whorls came from. But if you mean really two real crowns, I really don't know how that would be possible.
