OK, probably a stupid question but a friend of mine in Korea just got a something called a 'light body wave perm'. IT LOOKS BEAUTIFUL. She looks like a fairy princess mermaid.

Does anybody know if those exist in the states? Are they permanent? Stupid questions I know, but I've never even dyed my hair permanently before and I'm curious. I can assume that it would dry out and destroy hair but it's so so so so pretty.
