Judges like Ellen DeGeneres, Simon Cowell and Paula Abdul (before leaving the show) manage to share the limelight, too. But ever since Kara DioGuardi took her seat on the "American Idol" judges panel, she has turned heads.
DioGuardi is constantly switching up her long, brown locks. One week it's flowing and curly, the next it's pulled back into a high ponytail or worn straight and sleek.
But she didn't always have her strands altogether, if you ask her.
"Last year was really difficult," DioGuardi told Reuters. "I don't think people understood what it took to go from the back of the studio, writing, to 'Lights! Camera! Action!'"
She goes on to say, "I look back on last year and I see bad hair and the wrong accessories. I was moving as fast as anyone could move and learning as I went. You know, 'Maybe I'll try a ponytail this week?' Oh, no. 'Maybe I'll tease it up like Peg Bundy?' Uh, that doesn't look good."
Whatever hairstyle DioGuardi rocks, she has our vote for best hair of the season.
