Although she is best known for roles in "Cruel Intentions," "The Sweetest Thing" and "Hellboy," fashion has always been a part of the Michigan-born actress' success -- In 2010, she was even a guest judge on "Project Runway." Throughout her career, Selma Blair's hairstyles have changed as often as her outfits. From a short blonde pixie to long dark waves, Blair is never afraid to experiment.
