The star of The Twilight Saga loves experimenting with her hair color. When Kristen Stewart first entered Hollywood, she came in with natural strawberry blonde hair. In the biggest hit of her career, though, the world fell in love with her deep, chestnut brown hair. Since The Twilight Saga, Kristen has fallen for brunette hair. She wears a variant of brown most of the time.
