Save time in the morning by prepping before bed: Wash your hair, apply a smoothing serum, and set your hair, says Harry Josh, a stylist and a creative consultant for John Frieda Hair Care. For loose waves and smooth roots, Sarah Potempa, a stylist in New York City and the inventor of Beachwaver (a rotating curling iron), suggests splitting hair into two sections, then twisting each side back, away from the face, and wrapping into small buns, Princess Leia–style. Secure with bobby pins; release (and shake out) in the morning. With short hair, secure the top half into two ponytails, pulling the hair only halfway through to create a rumpled A.M. texture.
This technique also works on dry hair—just spritz on a salt spray first.
