You could also just give him and his enclosure a good misting. A bit higher humidity may well help him slip that stuck shed. If it's not fully encircling and is just a bit of old skin stuck on his head, then it's not even a real worry and can wait a day or two if you're concerned about bothering him while he's digesting.
