Valar morghulis—all men must dye...their hair, that is. A week after taking her natural brunette tone to a rich navy, Maisie Williams changed up her look once again, sans the visit to the Hall of Faces. The star had her hairstylist Jack Merrick-Thirlway create a super-vivid turquoise, which she debuted at Wimbledon while working a two-piece Victoria Beckham ensemble. "You know you're cool when you can pull off bright blue hair," the pro wrote on Instagram. We second that—a girl is Arya Stark of Winterfell, and she's got a pretty killer new 'do. Get a closer look at Williams' hair, and see even more celebrity hair makeovers in our gallery.
