Short Cuts of 2010

Heroes star Hayden Panettiere is no stranger to changing up her hairstyle - in the past year alone, she's rocked a sharp blonde bob, long blonde curls, dark brown waves and a strong auburn hue, with mixed results. So it came as no surprise to see that she'd gone for the big chop earlier this week, debuting a chic pixie cut. While it certainly places an emphasis on her facial features, the short cut also makes Hayden look much older than her twenty years, which I'm not so sure is a good thing in Hollywood.
