Problem with hair

I have a problem with the fur/hair. I have rigged a simple human model and added hair on the head with the help weights and particles. But when I want to animate the head (look down) in pose mode, the hair doesn’t follow the head to rotate. How to solve? Thanks!

Where on the modifier stack is the Particle System in relation to the Armature? The Particle System (hair) should be below Armature.
