dry white head after healthy shed

Hi everyone,
I took my ball python from a Friend that could no longer properly care for him about a week ago. Lucius is about 3 feet long and seems to be healthy. He had a good healthy shed 3 days ago, came of in 1 while piece.started from his head and finished it all in his water dish. But now His head looks white and dry, I'm terrified something is wrong with him.he us spending more time than usual in his water dish. Should I take him to the vet?
Any recommendations would be great :) thanks in advance

maybe he got some pee dried on his head after shedding?

After the snake has been soaking for awhile(hours) take the water bowl and check it out with a magnifying glass to see if there is lil bugs in the water :gj:

Can you post a picture?

I will try to get a good pic tomorrow, he is being a but cranky tonight, I'm Thinking he is hungry.
