Mischa Barton is one of those stars who always seems to be changing up her look, whether it’s her wacky fashion sense or her ever-evolving hair. We just saw the actress in N.Y.C. with dark red hair curled into a retro ‘do — but only days later, she turned up in Ireland with bright blond curls! We love the lighter locks on Mischa, but we want to know what you think! Tell us: Do you love Mischa’s new blonde ‘do? Or do you hate it and prefer her as a brunette?
