Long Hair, More Sex, South Korean Study Says

South Korean researchers recently published a study in the Journal of Evolutionary Psychology, entitled (and stating its conclusion) "Wives with long and high-quality hair have more frequent sex." The study recruited 204 heterosexual married couples and asked them questions about hair quality, hair length, attractiveness, sexual desire, sexual frequency and sexual satisfaction. The purpose: to investigate whether hair is associated with attractiveness and sexual lives in married couples. They found that "[t]he results revealed a positive effect of women’s hair quality and length on sexual frequency." The researchers added, in attempting to explain that effect, that "[w]ives’ long and high-quality hair was associated with frequent sexual intercourse via increasing their attractiveness and, subsequently, their husbands’ sexual desire toward them," and that "[t]his indicates that wives’ long and high-quality hair may arouse positive evaluation as well as sexual desire in husbands, thereby promoting pair bonding in couples."

The short of it: keep it long, ladies. The study, however, did not find a similar positive effect in the quality or length of married men's hair.
