Despite its effortless texture, Zoe Saldana's low ponytail maintains a dressed-up appearance, and even gets a touch of retro glamour with the added volume at her crown. Her hairstylist, Mara Roszak, used John Frieda's Frizz-Ease Mousse ($5; drugstore.com) on Saldana's damp strands, then rough-dried them to add movement. "To create the perfect natural wavy texture, I loosely braided her hair and let it dry," Roszak said. "I took out the braids, and misted a hairspray all over her head to add extra volume and texture." The Bardot-esque height was made by gentle backcombing at Saldana's crown. Taking sections from either side of the star's head, Roszak overlapped pieces of hair down the back until she formed a low ponytail shape, then fastened the style with hair pins. And rememberthe tousled appearance is part of the appeal. "Allow pieces of hair around the face to naturally fall out for a soft, feminine look," Roszak added.
