So I took Nala out today to see how she looked after her shed. I noticed on the tip of her head is a white spot where it looks like the scale is missing. It's a pretty small spot. Here is a pic of it


I recently put her in a new enclosure that is part screen top. I haven't seen her rub on it at all but that doesn't mean she hasn't. Is this from rubbing on the screen or is it from her just rubbing her head to shed?
here is a pic of the screen.


and another pic of the screen in her old tub which she never had problems in.


Should I put something like neosporin on it or just let it heal? Will it scar or in a couple sheds will it be gone?
