Perhaps it's the grunge vibe that's pervading beauty recently, or simply a case of plain laziness! Two tone hair is everywhere this Summer, with starlets from A to Z working designer roots. This week, Drew Barrymore has been rocking the red carpet on both sides of the Atlantic for her movie Going the Distance sporting tousled locks with brown roots and sun kissed curls at the bottom. She joins Ashley Simpson who's been working jet black hair with auburn tips. Rachel Bilson, Leighton Meester and Alexa Chung have all been rocking two tone hair colours. They join the original champion of the look Sarah Jessica Parker who was exposing her roots way back in to Sex and the City 2 and continues to bare them for events. Personally I love the look. It's definitely got an effortless beach boho vibe to it. Are you a fan?
