Transformation

Not everyone can pull off a bald cap. But when Cameron Diaz sported a Mr. Clean hairstyle for this year's My Sisters Keeper, her natural radiance—and mile-wide smile—made it look like the latest trend. "She makes it all seem effortless," says makeup artist Troy Jensen, who has lined her blue eyes with dark pencil and coated her lips with beige gloss. "Her California-girl approachability makes any look work." Adds hairstylist Lona Vigi: "She's always on top of her game. She knows what works without trying hard."
