Well, when I got it cut, I really needed to. I told the person who did it to keep it as long as possible, but I lost about two inches in the back, I think. It's still pretty long, but I've got my layers and whatnot back. Next time I straighten it, I'll take a picture so you can see.
The same thing happened to me at Christmas...I showed you guys my really short hair, didn't I? It's growing back now but the front part got damaged during Hello Dolly, so my bangs are all ratty and uneven.

I guess it's possible. Mine is really curly curly right now, but it goes through phases where it's just flat and wavy (alas, all the photos I have of myself are during this phase, so I don't share them). Right now it looks good, though. *knocks on wood*
