How to get jrock hair without backcombing/teasing?

Sorry to break it to you but the only way to get the results that you want is by teasing your hair. However you can try a shitload of gel or hairspray, but then again the chemicals in hairspray / gel have potential to dry out your hair and may actually be worse than teasing it, that and I doubt it will give you the results you desire. If there was a magic way to style your hair like that without the damage no one would tease their hair.
