Blondes are not a different species! You find them - male and female - in the same places that you find anyone else. I saw some today. Admittedly in Qatar there are fewer of them. Did you think there is a special blond zone where these creatures of your fantasy just hang around, longing to meet somebody who cares only for the colour of their hair? Sorry buster, you got that wrong.
The question you should be asking yourself is why your are using something as juvenile and trivial as hair colour as a 'selection factor'. Fact; hair is dead. It is mainly composed of a protein called keratin. Try being less shallow and maybe you might end up having a meaningful partnership, because you certainly can't have a relationship with strands of dead protein. Try shifting your focus away from hair; remember, not far from the scalp is the BRAIN within. Scary, eh? Maybe, but actually infinitely more interesting.
