A little off the topic, since many of the human hair used in sheitels comes from Idol offerings from India, which are called זבחי מתים wouldn’t that make them, the sheitels טמא ? The question is do they have the same טמא as מתים. If so a כהן can’t into to a building in which a women is wearing a human hair sheitel as that would make it a case of doubtful טמא in the ( רשות הרבים ) and would make him טמא . This might require separate buildings for the women in Simcha halls. This could also be a good excuse to claim you need to work from home if you are a כהן .
