Nearly every grooming company is launching what's called a "stubble trimmer" these days, which makes the following research from Northumbria University (and first reported in Men's Health) pretty fortuitous: When women were shown the same face with various degrees of facial hair, "Women rated light stubble as the most attractive, and said a man sporting it was the ideal romantic partner." Has something to do with testosterone, apparently. Meanwhile, men with full beards were deemed to be the most masculine and aggressive, but unfortunately, "they bottomed out as the least attractive." Just try telling that to Paul Bunyan. Or Santa Claus. Sorry, fellas.
