Some of you may remember the BP that I adopted and if not here's the thread

Now about three days after I fed him for the first time, I noticed that he was all shiny and that his eyes had clouded over. The temperature in his tank is 88-90 on the hot side and 78-80 on the cool side and I bumped his humidity up to 70% from 50% and his shed was still all over the place. It was in a million pieces with a very large piece going down his back and absolutely nothing off his head except for perhaps the bottom of his jaw.

First question is, with his tank parameters being correct, will this shed problem fix itself in time, am I doing something incorrectly, or what?

Next question is, I helped almost all of his shed off except for what was on his head since I didn't want to hold him down and force him to soak his head and with him being a bit head shy I don't want to overly stress him out by rubbing all over his face to get the skin off. Do you guys have any suggestions to get the rest of the shed off?
