Hair does not move the same as Genesis head

Scoopey

Hello there folks,
slightly strange problem here. I have the Pure Hair Messy for Genesis and noticed that when I bend my character's head the hair does not track the movement properly.
I have used magnets on it to make it fit a hat and discovered if I parented the magnets to Genesis Head then they failed to work with anything but the T-Pose. I therefore parented the magents to PH Messy head and they seemed to follow the Genesis had bends.
However it was then I noticed that the hair does not seem to be tracking Genesis's head.

Anyone have any ideas as to what it going on as I'm sure it is not the magnets causing the issue?

Regards
Steve C

P.S. I tried the sickle hair and hat fix for Genesis but the Adventure Hair I'm using points up at an angle so it does not work in this instance.
