Even though Lauren, 27, rocked her platinum blond bob, this hairdresser from Newport Beach, Calif. decided she wanted a more exotic look. “So needless to say, I used myself as a canvas,” Lauren says. To get her dark, long hair (hard to get more different than that), Lauren added extensions (“No way I could grow my hair that fast,” she says) and dyed it a rich, chocolate brown. Lauren loves the result, and to keep her long hair in check, especially with ample straightener and blow dryer use, she swears by Paul Mitchell Super Skinny Serum, $20.
