This theory holds that humans are naturally drawn to novelty. As problem shoppers, we get that. Cavemen were apparently so stunned by the appearance of a blonde gal that they couldn't help but abandon polygamy and commit themselves and their sperm to her for life. That prehistoric preference for blonds led to more blond babies, and thus, what might have been a lost gene turned into a fairly prevalent one (although blond hair is still less common than black or brown). (Jezebel)
Today, the societal value on fair hair is obviously wrapped up in a lot more than just biology. In your experience, does that age-old penchant still exist?
