After her role in "The Vow" opposite Channing Tatum, McAdams kept her bangs blunt. This lady is obviously beautiful in every hairstyle, but we think the bangs hid her face a little too much at the February 2012 premiere.
Messy and pulled back at Toronto Film Festival premiere of "The Wonder" in September 2012, McAdams let her roots show a little.
She went back to the wavy blonde style most associate her with at the September 2012 premiere of "Passion."
McAdams debuted a new shade at "The Wonder" premiere in Los Angeles in April 2013 with a hairstyle we usually reserve for doing laundry on Sundays, but she still (sort of) made the headband and messy top knot work.
