Probably a more robust test would be asking the caller to run their hand through their hair a few times. Maybe you could pre-render a few samples, but it would be trivial to request the person pass their hands through their hair in a specific way, or simply do it again after their hair is already messed up a bit from the first time. It could still be defeated by the caller having the same hair style (or wearing a good wig) as the person they are imitating, but then making someone look like someone else with practical effects has been a thing forever and it has not been a huge problem.

in my career i've personally worked with no less than half a dozen bald coworkers. i do think this is a good idea but won't work for everyone

  why wouldn't it still work? Hands in front of faces are already a huge problem for live deepfakes, wether or not the faker or the faker are bald shouldn't make this much easier. The only scenario this wound't be extra difficult for is if both the faker and the person being faked are bald, and even then the presence of a hand will likely cause some artifacts.

> run their hand through their hair That would have trouble passing anti-discrimination requirements: disability (no hands), medical (bandanna covering cancer treatment hair loss), religious (burka, rasta, yarmulke, sheitel), racist (cornrow). And trouble with: dreadlocks (can’t run fingers through), bald headed guys (as mentioned by sibling comment), and people with hairdo’s (coiffure, hairspray, topknots, plaits etcetera).

  It doesn't need to be literally their hand through their hair, it just needs to be some action which is easy to perform but complicated to photo-realistically simulate in real time from an arbitrary starting condition. Have them tug on their clothes to see how the fabric moves, have them or a caretaker turn a nearby light on and off such that their illumination changes, etc.
