Some celebrities change their hairstyle and/or color more than I change my sheets. Others are a little less adventurous with altering their style, but that doesn't mean they can't create a bevy of looks with just a flick of the bobby pin here or a styling product there. (Of course, having world-class hairstylists readily available never hurts.) Check out some celebrities and their changing hairstyles — some more daring than others — and vote on your favorites.
