Re: Full shed except head?!
Welcome to BPNet Tobias. You could soak her but likely the easiest way to get it off her head is to dampen a small pillowcase and pop her in. Close it tight with an elastic band or a knot, place the entire thing back in her enclosure on the warm side and let her wiggle around for a bit. She's not likely going to enjoy this terribly much but it should help that stuck shed come off her head.
Re: Full shed except head?!
My girl had the same problem during her first shed.
The skin around her jaw hadnt become loose at all. After 2 nice soaks, I used a humid hide.
I dont think my humidty was bumped up quite enough.
Good luck - I know how worrying it is!!!
