I think one of the problems using existing dynamic hair props is that most were set up some time ago prior to some of the rendering performance developments of the latest versions of Poser (P8 & Ppro2010). They were set up with the limitations of the software at the time.

What I've been starting to find is that we can take some of those props and make some adjustments, namely increasing the number of hairs and reducing the root/tip widths in each dynamic group. Exactly to what degree you might choose to do this will still depend on the particular group and how long you're prepared to wait for a final render.

I took Shena hair by Adorana and upped the number of hairs in some of the top groups to 300-400, and reduced the root/tip widths to 0.2 or 0.3 and 0.1 - see the results of this in the most recent renders in my gallery. What you start to do in this way is produce a head of hair with realistic hair numbers and dimensions.

The drawbacks, aside from render times, are that you find that some of the hair groups may begin to interfere with each other in terms of how the shaders render under certain lighting conditions (over-shadowing becomes a problem in areas, IDL can be interesting). It may be that the approach to making dynamic hair props needs to change somewhat to accommodate what the renderer can do now.

Hair shaders might need some adjustment also - I found that I no longer needed to have the 'opaque in shadow' box ticked on the hair node (the hair was doing this by virtute of the sheer number of hairs). I've also stopped using translucence in the shaders, only using tiny values to create a slight lift to tones where necessary.
TBH I'm not entirely sure how the hair node works, and I've had quite a few unexpected and disappointing results from long renders. Perhaps in time some of the shaders in the material room will need to be upgraded to account for recent advances in lighting and rendering options.

But with Poser 8 and pro2010 a realistic dynamic hair has suddenly become a lot more feasible.
