The real reason why she switched? Witherspoon's new role in The Good Lie. "This rich brunette works with Reese's coloring because it has movement and different layers of warmth and depth that show off her naturally beautiful skin and eye color," she told InStyle.com. If you're inspired to make a similar change, Goddard recommends looking for a few brunette shades you like before you head to the salon so you can bring examples to show your hairstylist. "It is important to find some visual images of brunette colors you naturally gravitate towards," she said. "Ask your colorist to review the depth and tone with you to establish which colors work best with your eyes and skin." After you shift shades, incorporate color-preserving shampoos and conditioners into your routine to keep your hair from fading. See more celebrity hair makeovers in our gallery!
