"Make sure to brush up, and get the roots of the hair as hot as the skin underneath can handle," says Garner's InStyle cover stylist, Ward Stegerhoek. "Dry in 2-inch sections-you need a nice amount of hair to heat it up and keep the temperature." Quickly roll up each section in a Velcro roller (1amp#189;-inch roller is best) before it cools. After 30 minutes release rollers and lightly brush out hair with your hands to soften the look. To make the accent curls around the face use a amp#190;-inch round iron to flip up and out from the face.INSIDER TRICK "Use lots of wave-control spray to get the best result," says Stegerhoek. "It only works properly if you spread thoroughly through the hair. You still get a soft, not crunchy look."BUY ONLINE NOW No Frizz Styling Spray, Living Proof, $14; sephora.com.

Flip your hair over and blow the hair half-way dry. Flip your hair back over and curl using medium rollers. Spray on a light hairspray and let hair cool. After a few hours remove the rollers and run your fingers lightly through the curls to loosen them up. Make sure to allow yourself enough time to wash, dry and let the curls sit in the rollers for a few hours so it will last all night.INSIDER TRICK "If you don't like rollers, an alternative is to use your own fingers," says Daniel Fortunato of the Patrick Melville Salon and Spa. "Twist the hair and circle into a little bun and pin it up."BUY ONLINE NOW Volume Expansion Spray, Kerastase, $26; luxuryparlor.com.
