Before: Lisa Wells, 51

“I’ve had the same hair all my life,” says Lisa, a publicist and the mother of a 14-year-old son. “It’s always either Chia Pet or frizzy bob, though there were phases when I blew it out. But that was such a big commitment.” In desperation, most days she ends up just clipping her hair into a bun. And the overly dark shade she uses to hide her gray isn’t helping matters either. “I’m excited to have a professional evaluation,” she says. “I hope it will change my life. . .or at least deliver hair that has style and sophistication.”
