Liv Tyler
The sharp side part adds sophistication to this style. Stylist Renato Campora, who created Liv's low pony, kept the front panel of hair from falling out by applying Kerastase serum to the hair and then bobby pinning it by the ear. He styled the rest of the hair in a low ponytail and when the whole look was set, he removed the pin and finished with Kerastase hairspray.
