"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.
