It doesn't seem to be a conflict.
It's probably not personification because a real person is doing the actions.
It doesn't really talk about herself as a person, no thoughts- no speech. I don't think this is characterization.
Foreshadowing is a warning or indication of a future event. It seems like something changed in the passage. She started to let down her hair. Maybe this is a leverage into what will happen later in the story? I don't know what the story is, but I think this is the best answer.
I hope this helps!
