Saucey, my snake has similar dry spots on his head, and a few on his body. Although they are very small and seem harmless, it's still annoying. I am in the same boat, as my humidity is in the ideal range. You can only see the tiny dry spots when he is directly under a fluorescent light. They are so small and so few that I'm not even going to worry about it. I'd wait it out until your next shed to see what happens.
