Hello!
Recently, I took home a baby ball python from a local pet store, who happened to have received some sort of cut/bruise on the top of her head. She came with 2 topical medicines (Silvadene, a cream, and Nolvasan, a liquid to be mixed with water) to be applied twice a day. She was an absolute sweetheart, and stayed surprisingly calm when it came time to apply her medicines. We diligently followed the schedule, until she started showing signs of shedding. When her skin started flaking off, I gave her a break so as not to stress her out (and I also assumed the silvadene wouldn't properly absorb into her skin if it was lifting off of her).
A few days after that, I gave her a soak and gently rubbed some of the skin off of her back and tail, which she finished later that night. So, obviously, snakes shed starting from their head and wriggling the skin off down the body, usually coming off in one or two big pieces. However, this girl isn't doing that, and the skin on her head seems to be stuck. I notice it around her eyes and the tip of her mouth- which looks very dry- and I notice especially on her head that the skin seems to be "cracking." There also seems to be some silvadene cream stuck under the skin.
Unfortunately, I don't have a picture of her head before the shed, or when we first bought her, but here are some pictures from today.

I'm thinking about seeing the vet that prescribed her medications, but my mom would rather see our regular vet (who doesn't really do reptiles...).

As for technical information, she's almost a year old and I've had her for a few weeks. Her temperature is normal. As for her humidity (which affects a lot during shedding), the resting humidity for our house is very low, so I spray her cage thoroughly and often. While the overall humidity in her cage is only around 50% (up to 55% right after sprays), she has sphagnum moss in her two hides, and they are very humid (I picked her up for the pictures and she was damp).

So, if anyone knows what I should do for her (regarding medicine, humidity, vet care, or just general husbandry), please tell me what to do!
Thank you!
