I completely agree with XP minus the need for raising humidity. I've never found that to be the case in my experience. I personally don't believe in assisting with your dragon shedding at all, and I never have done so. If your dragon has items in the tank it can rub its face on, it knows how to get rid of the nose shed if it needs to.
A lot of times, we think it bothers them more than it actually bothers them.
