I recently noticed a patch of what I thought was just some substrate stuck to my tegu’s head, I have been working a ton of overtime so I didn’t really get the chance to check it out. Today I finally did really look at it and it looks like it may be stuck shed but it’s really thick and doesn’t want to come off. I put some shedding aid on it and tried rubbing it in / attempting to get it off. I got a patch of it to peel off but it looks like just exposed flesh. Anyone had this problem? Any suggestions on what to do?
