I don't get head shaving. It always makes the person look older and more boring.
Not at all. And actually, it definitely has the opposite effect if the guy is already balding. Who do you think looks younger, stronger and sexier: a balding guy, or a guy with a shaved head? And even when they are not balding, some men just don't look that great with hair, and head shaving only makes them look more striking and more badass. Compare Michael Jordan with and without hair. Avery Brooks is another good example.
