What is your setup like? Type of substrate? What's your relative humidity?
I have found if a snake has a stuck shead all they really need is high humidity and something to rub on. I made this "humidity hide" it's separate from her security hide. I just stuffed a 28 qt bin with reptichip and moistened it down. The cage sits at around 60-70 humidity, but her humidity hide is always at 99℅. You wouldn't need one this big as your snake is much smaller. But they can enter the humidity hide and it helps them work off the old skin.
