Is kristen stewarts hair naturally straight, or wavy, or curly??

I think wavy :s

curly

I think that her hair is straight but with a touch of a wave at the ends giving it a bit more volume, I found a picture which I was trying to describe until I found it;
I think this is what I'd expect her natural hair to be like:

This is probably what I'd expect her hair to be like

when she was younger she had straight hair and then around 14 or something she got wavey hair and it is wavey but she has to change it lolz
