Hi,

When the shed completely encircles the body is the one time you need to do something about it.

If you don't it will shrink as it dries and can cut off the blood supply causing the loss of the tail and infection etc.

I would get a plant mister and boost the humidity in her enclosure for an hour or so then take her out and spray the stuck shed directly and try and remove it by rolling from the point closest to the head end down towards the tail.
