Hayden Panettiere loves changing her hair color and style! We've seen her in everything from red, black and blond to long, short, straight and wavy! But we can't decide which look is our fave! Well the blond, sweet and innocent look did work in '09 but we just love the short and edgy look that she's been rocking since then! Click on the pics and tell us what you think, short and blond or black and long?
