In terms of Bey's next move, obviously, there's no telling if she'll stay in the same palette, or go darker, or even move away from blond completely. "Everything and anything is possible at any moment with Beyoncé. Who knows?" Hazan says. "Just be ready, because it will happen at some point, I'm sure of it. That's what makes her one of my favorite clients. She changes so much, and as a colorist, it's exciting not to do the same thing every time you see someone. It's fun and it's a good relationship. I can handle whatever she wants to do and keep her hair healthy at the same time."
