Answers: In certainty what you need to do is put it within a dry place, not a humid place. Humidity makes wood expand. You may want to try putting it surrounded by your oven for a little while at the lowest possible setting. It should do the trick if it is within fact humidity cause the problem. If it's something else, like paint or paste, it will also likely relieve to "melt" or loosen the glue.
Most importantly when you're first night the doll, twist from the middle and not the terribly top, as the top could break under torque. You may also want to use a strap wrench but they aren't other in everyone's tool box.
Put into freezer for give or take a few two hours
