These are just a few ideas of questions that will greatly help in the answering of your questions.
Many problems can occur which prevent reptiles as a whole from shedding. For instance I have a Silk back and generally have no problems when she sheds as long as I put a few drops of organic vitamin E oil in with her soak water and allow her to soak for about 20min. Easy shed every time.
Your problem is a dragon that is not shedding. Mine was a dragon having a hard time with retained shed. If you can tell us more or all about the conditions in which the dragon is kept. All info will greatly increase the ability of all parties present to help. Sometimes it can be as simple as raising temps, (fixing a lighting problem) and sometimes it can be the sign of a worse underlying problem causing stress on the dragon.
Thank you and I hope we can get to the bottom of this and help you along your way.
Peace, J
