My normal had a very bad shed and all is gone now except 1 cap. I tried fussing with it a bit and did put her in a humid box, tried a small piece of scotch tape, a q-tip, etc. Nothing worked. I came to the conclusion that I was stressing her out more than the cap was despite her rubbing it on everything she encounters and being clearly annoyed by it.

At the end of the day I'm just gonna push past my urge to peel the sunburn and let her deal with it on her own with her next shed.
