Well I had to create a trapcode particular effect for certain strings. I set them to no velocity and a high amount with some wind headed in the direction the hair was blowing. Then I tracked the emission point to certain points on the hair. This made the string have the effect on down the line of the hair movement that created it. I did a few of these and then created a strings pattern and expanded the matte of the actress and blurred it and used that to drive a displacement map of the other particles so they inherited the movement of the hair. Mixing these with the tracked particular strings did the trick and created the correspondence.
