Jessica Chastain is an Oscar nominee, fashion plate, and, let's face it, enviable redhead! So when she chatted with InStyle for our March issue's "Beauty Talk," we had to ask her one very important question—is it natural? "Yes, and as a child I didn't like it because it made me different. But as I grew older and more comfortable, it became a badge of honor," she said. The actress revealed that when a role calls for a different hue—like when she went blonde for The Help—she always wigs it. But if she did make a change, she'd do a major one: "I'd go in a completely opposite direction: Gwen Stefani platinum!" Bombshell!
