Kim Kardashian is as famous for her lush raven locks as she is for her curves. but she recently decided to change her tresses — at least temporarily. Her colorist, Rebecca Friedman, co-owner of L.A.’s Goodform Salon, tells PEOPLE, “She wanted to go lighter and brighter for summer.” Not that she got in and out of the salon in a minute, as Friedman explains, “It took about three hours to do varied tones of highlights, plus a glaze for shine.” And what does Kardashian think of her newly lightened look? “She loves it,” the stylist says. “It gives her hair more dimension.” Want to give highlights a try? Friedman has a tip for anyone else who’s thinking of lightening her locks for the warmer months: “Don’t go more than two levels lighter and if you want to do highlights, especially if you have previously colored hair. Definitely leave it to a professional.” Tell us: Do you change your hair color in the summer months? Reporting by Marisa Laudadio
