what if they need a hair cut?

@AmericanButterfly
Maybe they don't see hair as a part of the head, but as something attached to it.

@EricTheRedAndWhite maybe it's a contest thing too since barbers usually wash the hair too

@AmericanButterfly The context they mean is head patting [ specifically the top part of the head ] because the head is a really sacred area of the body in Eastern culture. Having your barber/hairstylist touching your head is completely fine

@Kumi oh so don't pet other humans I get it thanks
