Missing Scales on Head

My ball python has a few missing scales on the top of her head. I'm guessing she scraped them off somehow. Any idea what this could mean? Should I be worried? Does it need to be treated?

what's her weight and what are you feeding her?
can you give us a run-down of your husbandry?

It could be a scaleless head morph. Post a photo of her vent, the scales down there should be split if she is a SH.

Does not need to be treated it's obviously clean, not red or oozing.

Simple head rubbing IMO
