McAdams appears on the cover of the February 2012 issue of Glamour magazine. She talks about her hair styles with the magazine.
I always wanted pink hair. I wanted to do my whole head, but my hairstylist, Robert, was like, “How about we start small?” I absolutely loved it. I still think about doing blue at some point, but I don’t like to change my hair before I’m about to do [a film]—you never know what that character’s going to be.
