Forget bouncy, tumbling curls and sexy bed-head hair and just opt for a Betonfrisur (literally, cement hairstyle). No cement is actually needed to create one; a dollop of gel and a triple spritz of hairspray should be enough to keep everything in place for at least a week. Of course those who take the time to create a Betonfrisur put a priority on looking great - whatever the weather. But there's one sure-fire way to annoy them: Just run your fingers through their hair!
