THE LOOK Old Hollywood glamour HOW-TO Stylist Lona Vigil channeled Veronica Lake for Diaz’s Oscar hairstyle. “She wore such an elegant dress, so we wanted a very 'movie star' moment,” says Vigil who used a round brush to blowout Diaz’s hair with a Velecta Paramount Paris 4000i dryer. Vigil finished the look with hot rollers and then brushed her golden locks to one side before spritzing it with Elnett. INSIDER TRICK After you get the initial volume this look demands, use the ionic setting on the dryer, for extra shine. BUY ONLINE NOW Velecta Paramount Paris 4000i dryer, $199.95; beechergroup.com.
