The hair do not really need to be real figure. Just parenting works just as well. In fact the Poser hair that comes as "Hair", as opposed to "Figure" is just that, an obj parented to the head.

When you export from Daz don't forget to check for "Merge Clothing Into Figure Skeleton", you don't want every item of cloth to be separately rigged. (Will not work in Marvelous Designer among else). Also when you export direct from Daz to C4D R14 do NOT check "Frame Rate" in the import settings. It breaks the import.

But one of the drawbacks with importing directly from Daz to C4D is that you get the parameters of every little finger and other unnecessary garbage. Motionbuilder is ideal in the context because for the first you can enhance the animation in a professional way and for the second it allows you to export only the parameters you want. You do that by constructing a skeleton avatar with the bare minimum of joints that is exported together with the animation. This skeleton drives the full figure in the final animation.
