Your Most Stylish Year Ever

You want to avoid over-drying your hair, says Manhattan-based stylist Michael Murphy, who has worked with supermodels Naomi Campbell (at left) and Elle Macpherson. This also forces variety—instead of blowing your hair dry, let it air-dry and wear it up or put it in foam rollers for a new wavy look. If you do blow-dry, "always use a nozzle on the end of your dryer," says Murphy. "It keeps hair from frizzing and prevents it from getting too close to the hair and burning it."
