i think her hair looks natural! the curls are so big, and they look like mine, and mine are natural!(i have even more curls when it's newly washed! LOL) but i have seen a film where she plays the sister of some guy, and i think her name is Cat in it. and if i don't remember wrong she had strait hair there, and it didn't look like it was straitend.. but i don't know... it looks natural, but it can be fixed as well!! 🙂 but i don't think it's a perm! i think that if the curls not are natural, then i think they have used an curling-iron!! it looks like that!
