Hair-y Potter: Emma Watson/Hermione Granger

Emma Watson has portrayed Hermione Granger since 2001 in the Harry Potter films. She was only 9 when she landed the coveted Female lead in the film adaptation of the book series. She gradually grew out of her signature mousy brown frizzy hair and bangs and has recently been rocking the red carpets with an adorable pixie cut.
