On Sunday, at the premiere of A Most Violent Year, Zosia Mamet unveiled a new hair look: Her bob is now an ashen gray, with a few black strands peeking at the roots. What could have inspired this very mature look? Think of it as a colorful reminder that though she may be a Girl on TV, she's certainly a woman offscreen.
