You might try Kirwyn's hair proxy:

It's free dynamic hair, along with a "proxy" to help run the simulations faster. 

It comes with a tutorial that helped me a lot with dynamic hair. 

Though Kirwyn's default is a little "staticky," I was able to get to to lie a little flatter by changing the settings. 

I still think it will be quite difficult to make dynamic hair and prop hair match, though.  Probably better to stick with one or the other.
