THE CUT Long layers sliced all around the head prevent the "triangle" effect that you get from a blunt cut. "I use thinning shears on Kelly's ends to give the waves lightness and movement," says stylist Mark Townsend.
STYLING SECRET Towel-dry and apply a leave-in conditioner from the mid-shaft down to preserve volume at the roots. Blow-dry with your fingers, then define waves with a 1½-inch iron.
SHORTCUT TO GORGEOUS Let clean hair dry overnight, then wrap 2-inch pieces around steam rollers, twisting all the way to the scalp. After 15 minutes, remove rollers and smooth the ends with shine serum.
