Whats with some girls preening their hair?

Is it like a nervous type thing? I just watched a girl walk into and out of the gas station from her car twice. I think she forgot something, but she was moving her hair out of the way the whole time she was walking across the parking lot. Maybe it was the wind, but she didn't really look happy. by the way I was just sitting in my truck while it was filling up when I noticed this. I always think it's hot when girls do the hair preening thing by the way
