Thank you everyone for replying so fast with a lot of useful information.
 
I guess my best bet will be to either create hair from scratch in the dynamic hair room or purchuse some products that you have recommended here, already set up as dynamic hair. 

By the way all of the hair you linked me to seems to be v3 hair models do you know of any v4 dynamic hair models?

What would happen if i applied a windforce effect to the polygon hair?

cheers
