It's no secret that Rachel McAdams has one of the best manes in Hollywood.
Canada's Sweetheart has turned heads with her many hairstyles ever since she gave us serious hair envy as Regina George on "Mean Girls." (We realize that she was wearing a wig; she wore it well.)
But even on the red carpet, the "True Detective" actress isn't afraid to take risks, whether it means dyeing her blond locks pink or opting for a curly brunette bob.
