The change is subtle, but it's there: Kate Bosworth’s hair has a new ombre effect. We noticed the star's deeper blond roots at the Target and Neiman Marcus collaboration launch party in New York City last night, and it turns out, the change was a result of her role in the upcoming film Homefront. "I kept it pretty laid-back for this last role," she told InStyle.com. "They added paint and darker roots to my hair, so this is my natural color at the top that was painted a little darker." We've heard of balayage, where dye is painted directly onto the hair shaft to create a natural fade, but to play a such gritty part, Bosworth's version tipped more toward arts and crafts than salon couture. "It's literal paint. They'll take alcohol and use it with the paint, and it stays on," she added. Now that's commitment to character!
