While most of us put our hair in a ponytail for trips to the gym or casual days spend chilling out at home, Kate Beckinsale has turned the style into her red-carpet trademark and worn it to all manner of high-profile events, from the Oscars to the Grammys. But these ponytails are anything but basic. With added teasing, curls, and copious extensions for volume, Kate's modern updos definitely take the ponytail to the next level. From sleek styles with cheerleader-esque curls to messy, modern textured looks, she and her hairstylist constantly find new twists on the look. Pulling the hair off the face makes the most of Kate's incredible bone structure and injects a fun, youthful element into her red-carpet style. Over the years, she has made this look her own, and we love every twist on the look, from the fun flipped-over pony to the sexier bouffants with loose strands around the face. Take a look at just a few of Kate's best hair moments now. Maybe they'll persuade you to try a formal ponytail in the future?
