it's unusual to be able to expose enough of the headgear to remove it with completely removing the shroud.
The shroud usually only has a couple of turns before its in position - you may well be able to unscrew it but it can't lift up because the head is holding it down
Try to get the head off then the shroud then the headgear - honest it will work !
