>>10704614Are you sure you're not just too scared? There's usually a little bit more resistance as you twist the head up, but if you look at the back of the head you should see if there are any parts touching. Until then, you should be able to pull the head back.
I took the wig off Synth Human, you can pull the head safely until the neck part touches the bottom of the skull. If you force it further it will pop off the joint, but until then it's fine.
(I assume no responsibility if you break it lol)
