How should I care for my Korean hair? :p

So I'm half Korean, but blessed enough to have the Korean hair. It's generally a bit thicker than Japanese hair and doesn't lie nearly as flat. I was wondering... what should I do to take care of it? I want it a bit glossier, especially after a shower (poofs a bit until mid-afternoon).

Anyways, any suggestions would be great! I've heard something about rinsing with cold water, using special shampoos... I'm open to anything that won't kill my poor wallet. :]

Thanks!
