If you noticed loose scales, chances are what you're seeing is a stuck shed. They don't normally get loose scales and should shed entirely in one piece. It's tough to see exactly what's going on beyond REALLY wrinkled skin in that picture (which is certainly not normal - even when they are in shed).
Here are two threads to read through that should help you out:
