What she means:How does Natasha Romanoff have curly hair in one Marvel movie, and straight hair in another? If she straightens or curls her hair, how does it stay? Does she have access to a flat iron or curler on missions? Like in Captain America: The Winter Solider, her hair is perfectly straight. But after a while, wouldn't it curl up just a bit? In Iron Man 2, her hair is extremely curly. Is that the work of a curling iron or is it natural? If it's natural, why didn't her hair curl up or at least have some waves later on the CA:TWS??? How does she do it and can I have her secrets?
