Exactly!
I learned that even to be true with some salamanders.
When I first started keeping fire salamanders, some of them were losing patches of skin.
I called Michael Shrom, the salamander guru, and asked him what I was doing wrong.
He said that many people make this same mistake; they think that because salamanders are found alongside streams, they should be given a damp environment.
He told me to squeeze out all the moss and even remove the water bowl.
Sure enough, since I made those changes I've never had those issues.

I keep my vine snakes the same way as the grass snakes, despite all the literature to the contrary.
I just spray them down more when they're shedding.
