Reese WitherspoonTHE LOOK Unfussy half-up hair HOW-TO "Start with clean, damp hair so hair has movement and high shine," says Bumble and bumble stylist Michele Fiona. Spritz hair with prep lotion to create a workable hold, then blow-dry hair using a large round brush, curling the ends slightly under. "Then take two sections of hair by the forehead, twist gently and secure with a pin the same color as hair," says Fiona. "Finish with a light coat of medium-hold hairspray." INSIDER TRICK "Don't completely saturate hair with product, as this will discourage body and fullness," says Fiona. "This look is all about flirty movement."
