Yes...it sounds like it could be a retained shed. Try a shed box. Use a clear container with a lid...like a storage box from the dollar store. Run a washcloth under very warm water and put it in the box along with about a half an inch of water...make sure the snake can get it's head above water...make sure the water is nice and warm...but not too hot...you are trying to create a humid environment, but you don't want to cook your snake ....then put the snake in the box and close the lid. Leave the snake in there for about a half an hour. When you take the snake out, if the scales are still there, gently exfoliate with the washcloth. This always works for me when my snakes have problems with sheds. Steve has a video...if he comes on and reads this, maybe he can post the video.
