Awe, sorry you have bad shed stress. Just went through it myself

My girl had a residual piece of shed on her tail until her next shed. It was making me crazy. Soaking did nothing, pillowcase did nothing. I finally gave up and it all came off with her next shed cycle.

Absolutely either soak her or do the pillowcase method. Both accomplish the same thing. You may need to do it a couple times with a really awful shed. The most important thing is getting the shed off the eye caps and face. That seems to be what annoys the snake the most, so they take care of it first usually. Also, you don't want shed constricting the tip of the tail. Over time, it can cut off the circulation. But if you and the snake together can get the shed off of those mentioned areas but there are still stuck patches, just give it up til next time. Provided the humidity and temps are right the second time around, it will usually come right off. You're snake will just look kind of ridiculous til that time comes.
