Hahaha the hair thing reminds me of my brother at fourteen. He thought that girls were like, hardwired to play with their hair when they were horny. Like, they couldn't not do that. I had to explain to him that typically, girls just do that when they are fidgety, whether it's because they're nervous, bored, or anxious to get the hell out of there like I imagine this Lauren woman was. And that sometimes girls do play with their hair when they are flirting, but this is a deliberate attempt at being cute, not something that they are compulsed to do.
