New ball python owner

[thehonestpirate]

I recently bought a snake off of someone nearby, it's a baby, about 14 inches in length, He told me that she had eaten last Sunday, she is shedding right now and my question is, how long do I wait if her head and neck isn't shedding, it's been two days since i've had her and i dont know how long she had been shedding prior to that, when I got her she had the same amount of skin left on her head and neck. I am trying my best to do misting and keep the humidity high for her to shed but it doesn't seem like she is having any luck. I know that I shouldn't handle her to help her shed due to the move from her last owner right?
