I soaked him in ReptaRinse and gently peeled off all the skin which would easily peel, but he still has some stubborn skin stuck on his head. I think it's interfering with his hunting because he can't seem to nab crickets. He also has a sheath of old skin stuck on his tail. I gently peeled off old skin from his little toes after he soaked in ReptaRinse.

He is clearly deteriorating. What can I do???
