Are you sure he isn't going into a shedding period? Confirm proper environmental parameters, especially heat and UVB lighting. Low temps may cause stress which could cause him to become dull. Replace the UVB lights if older than 6 months. Mist him daily and use hygrometers in his enclosure to confirm proper humidity levels. Monitor for lethargy or decreased appetite. If necessary, have him examined by your veterinarian or a vet experienced in treating reptiles to diagnose illness or injury.
