PICK UP STEAM

Being perfectly moisturized is all about flipping on the steam when you flip off the lights, according to celebrity hairstylist Dean Banowetz. "One of the best things to do for your hair and skin is to invest in a vaporizer," he reveals. "It helps to put moisture back in the air that is missing during the fall and winter." For extra suppleness, "Add a little rose essential oil, which is known for its moisture properties." You can't beat one of these Japanese-designed humidifiers, $319 each, for looking cute while warding off dry winter skin.
