Model and Insurgent actress Suki Waterhouse has really good hair. Like, the lightly tousled waves that hair dreams are made of. When asked how she gets those perfect waves, she told Us Weekly that she rinses her hair with Coca-Cola. "I don't like my hair when it's washed — it's fine and limp — but Coca-Cola makes it tousled, like I've gone through the Amazon or something," she said. Like, the sticky soda? On your hair? Really?
