An experiment: Do men prefer curly or straight hair?

In an ideal world, it would make no difference. But the world is not ideal, so we have this social experiment, carried out in fascinating detail:

Curly vs. Straight: Which Do Men Prefer?

Then she takes it one step further:

There’s a twist. On my dates, the plan was to find out what they really think when I show up as the opposite of what they expect. If they reach out to my straight profile, I would meet them as a curly, and vice versa. Would my hairstyle really affect their attraction?

Interesting… How could collected filaments of keratin have such an effect?
