Twilight star Ashley Greene changed her hair many times since first emerging in the Hollywood scene, but as the cover girl of our new special issue InStyle Hair, she insists she’s still low maintenance at heart. “I love having my hair and makeup done, but I’m really just a 15-minute girl, throwing everything on with no fuss,” the 24-year-old actress and mark Brand Ambassador tells us. “That said, I do color and change my hair all the time!” And her willingness to play around with her look helps her when she transforms from mortal to vampire Alice Cullen on the set of Twilight. “The whole process takes about two hours,” Greene says of her otherworldly makeover. “My hair is pretty thick, and we wrap it and put it under a wig. To get it to fit so I don’t like look I have an alien head is a talent in itself. ” The next installment of the franchise, The Twilight Saga: Breaking Dawn Part 1 opens November 18th. For more of our exclusive interview with Greene, pick up the special issue of InStyle Hair, on newsstands Friday.
