Hi,
It's strange, I already replied to this post but I see my reply is not here, sorry, I had the same problem with another post, we are going to look into this.
To maintain the volume of the hair in the simulation play with the Damping parameter, if you use really high values you will have less movement in the hair, you should also add more damping to the roots. Play with the graph of Global Scale, reduce the scale at the root just a bit, is a matter of experimentation. You can control all sections of the simulation using maps or guide channels. For example, use a per-vertex guide channel painted in OxEditGuides to control several parameters in OxDynamics, you can paint only the roots or the tips of the guide to isolate or reduce the effect of certain parameters.
Painting Per-Vertex Channel:
Assigning the channel to a parameter:
