Rain, wind, and crazy temperatures can wreck amazing hairdos – and bad hair days can happen to absolutely anyone. If you needed proof, even the gorgeous guys of One Direction have experienced days where their curls went wild, quiffs fell out of place, and stubborn cowlicks just couldn't be tamed.
Harry Styles' curls have been straightened, windswept, and overgrown (yikes!), while Louis Tomlinson has had some pretty hilarious run-ins with blow dryers in his stylist's chair! The guys all keep a good humor about their wild styles, probably because they know they look hot regardless of what their hair is doing!
