For her hair, Sebastian Professional stylist Jen Atkin applied Mousse Forte ($12) at her roots on damp hair, then blow-dried her hair 75 percent dry. She then curled the ends under using a round brush, sprayed Shaper Zero Gravity Hairspray ($16) all over, and brushed it thru to create a base to hold the waves. Using a one-inch curling iron, she curled pieces in a clockwise direction and pinned the curls. Once the curls set, she let them cool for 15 minutes, then unpinned and brushed out the curls. To finish, she set Christina's part and stretched out her bangs using a flat iron to get a smoother look toward the front.
