Hello,

How are you exporting the hair from Daz? 

If you are exporting it as polygon mesh, you can convert it to Ornatrix hair using the Hair from Mesh Strip node. 

If you are exporting it as curves, you can use Hair From Curves.

If you are exporting is as alembic, you can use Ornatrix Alembic. 

Let me know if this helps.
