HIGH SHINE

"I don't believe in changing one's hair color completely but enhancing what they already have instead," says star stylist Denis De Souza, whose clients include Mila Kunis. To achieve a high-impact, low-maintenance style that suits Kunis's jet-setting lifestyle, De Souza gives "more subtle highlights on top and brighter ones from the middle to the ends of the hair … the hair will grow out nicely without having that drastic line of demarcation." Another tip to stretch your color's life span? Shampoo only two to three times a week and condition the other days.
