Everyone has their ups and downs.
For Hayden Panettiere, this can apply to her hit TV show, as well as to her hair. Actually, just her hairstyles. There hasn't been an "up" phase for the former in years. You're welcome for that Heroes spoiler alert if you haven't seen it. Don't bother.
In any case, the adorable actress is certainly known for mixing things up when it comes to her appearance, as we saw in our earlier examination of Hayden's makeup.
As you can see in the photo comparison below, she trued tousled waves at the Spike TV Guys Awards, then pulled her hair into a sleek updo at the MTV Movie Awards.
