Hairstyles don’t just frame faces, they frame facial gestures. I wonder if having a shaved head – as I often do – doesn’t have a subtle but lasting effect on my social interactions?
We tend to read faces very quickly. It’s a handy skill (or weakness) from more chaotic days when human society was, well, savage.
A face without hair probably invites more focus on its gestures. I suppose this could be tested by having an actor, disguised with and then without hair, deliver the same lines and make the same facial gestures for test subjects.
Do clearer facial gestures simply amplify the signal or shift it?
