difficult shed

[AndyB]

my royal is undergoing its first shed since we got it, he's shed past his eyes but the old skin is still complete from just behind that to his tail, we'ver bathed him twice a day in lukewarm water, we've sat the water on the heat mat to give him a bit extra humidity, bathed him with the rock in his tank, but still nothing, the old skin is still tight against his head so we cant even help him out.

he's captive-bred, he's never eaten in his whole life and obviously we're not trying to feed him while he sheds, were running out of ideas, so if any of you guys have any it would be much appreciated.

his temps are 91F-85F, slightly less at night depending on house temps

all ideas are appreciated
