Yeah actually, there's one in the marketplace.  I tried it out, but it looks a bit flat, kind of like hair textured cloth... Which basically it is. :)   I give kudos to the merchant for trying hard...

And for more far distance renders, it works fine, but I'd like to see something that has more depth, and more detail especially a bit more close up. I tried making a similar hair myself half a year back, but I had similar problems with flatness.. 

Has anyone tried the dynamic hair in Carrara?
