I don't see where you mentioned an existing dynamic hair in your first post.

So far as dynamic hair props go: the most important thing is to find the right style, because you can get help with pretty much everything else. A hair prop you may not think is usable for your purposes may well be.

Even though I do find the Hair Room frustrating because SM seems reluctant to put a lot of effort into upgrading it, I still render with dynamic hair 90% of the time. Of course, my aim is realism, so my aim may be different than yours.
