LILY ALDRIDGE’S SHADE: Deep chestnut roots that fade to a tawny medium brown. WHAT MAKES IT HOT: You may not recognize Victoria’s Secret model Lily Aldridgebut chances are you love her hair. “It’s by far one of the most requested looks in my salon,” says Cunningham. “There’s just something appealing and easy about those bleached-out ends.” WHO IT WORKS FOR: Natural brunets will have the most luck pulling this shade off. Simply ask your colorist to add uneven ribbons of a lighter hueand keep in mind, balayage highlights, that is, those painted directly onto the hair shaft without foils or a cap, will look the most believable.
