I would give her a good misting with some warm/ not cold water and see if she sheds quicker. May be the air is dry making it more difficult?

I just had a banded gecko have problems , I held her in some water cuped in my hand and then used a q-tip very gently and sorta broke open some stubborn shed on her head and face. I think the heat being on in the house more so lately due to the cold weather had something to do with her problem. So I misted her tank a bit as well.

Just try misting her a couple times a day for a few days and see if it helps. Let us know how she does.
