Jessica Biel‘s hair and makeup looked relaxed but lovely at Thursday night’s premiere of “The A-Team” in Hollywood. Her soft waves are super easy to replicate at home, especially since celebrity stylist Mara Roszak, who worked on Jessica’s hair, gave us instructions. On damp hair, apply TRESemmé 24 Hour Body Foaming Mousse all over, especially on the roots. Part your hair in the center, then blow it dry using a round brush, setting the top in large pin curls at random (this adds some nice body on the top). Once the hair is dry, take out the pin curls and spritz TRESemmé Naturals Finishing Spray all over, then wrap the hair in a loose bun and let it set for 10 minutes. Unpin the bun, shake your head, and voilà, your hair will look delightfully tousled.
