cartoon hair in real life

That hair is actually not too outlandish.  I've seen real people with similar hair.  You'd definitely need some strong product, though.  Talk to people who spike their hair, or look for threads around here on spiking, to find out what products are good for that.  Then lock yourself up in your room on a night you have nothing to do, and experiment with your chosen products until you get the effect you want.  Oh, and make sure to wind-test it before you wear it around, to make sure it won't get wrecked ^_^ .  No sense spending all that time getting your video game hair perfect if the first wind will blow it all out of shape!
