Hair, intimacy, boy bands

According to evolutionists men have facial hair and women are hairless because these things have been selected for. Why does this conflict with the damage done to the music and movie industry if ALL MEN were suddenly to sport full (Armish) beard growth? Would Ricki Martin and the Back Street Boys still fill stadiums with female fans?

Could this be right: Beards are designed to create a feeling of intimacy because they focus attention on the eyes. May be privacy was once hard to come by. This seems plausible to me but I’m just guessing.
