“I’ve been giving it to Jennifer Garner to use, to just take down a little bit of the warmth in her tone,” he says. Instead, he reserves cool-tone shampoos (such as Virtue’s new clean-ingredient Color Kick debrassing shampoo) for those that skew icy blonde or even brunette. “That’s the beauty of this color-that there are actually a lot of yellow undertones to it,” Abergel says on a drive through his home base of Beverly Hills. In her case-with a “watercolor” dye job that Moon and her longtime hairstylist Adir Abergel recently created, inspired by Nastassja Kinski and David Bowie-that dawn-colored warmth is the intended effect, not something to counteract.
