She stole our hearts in The Notebook, and ever since, we've been in a love affair with Rachel McAdams'...hair. From her daring hot-pink tips (long before Kate Bosworth, Lauren Conrad, and everyone else did it) to her shiny retro curls, McAdams always seems to know what to give us when we want it. She's been dark, she's been platinum, and she's been everything in between. All that change might cause some people to get dizzy but for us, it's only made us crush even harder.
