If it isn't really bothering you, you can wait until next shed. But if it's bothering you a lot then soak her in warm water, then using a warmed wet q-tip, VERY gently roll the skin off. That is my last resort when there is stuck shed on my snake. If you haven't done so already, offer a humid hide during shed. All of my sheds so far have been perfect and I don't have to worry about humidity during shed.
