Taking a look at some solutions for generating Hair in Maya from ZBrush’s Fibermesh, Shaun Keenan provides a quick tip for using the Fibermesh as a guide in Maya to build the Maya nHair around.

In this quick tip, you’ll learn how to export Fibermesh from ZBrush and import it into Maya for use with Maya’s hair system

There are some good tips here for using the wrap deformer to have the hair move along with the model, and some tips for animation as well.
The Fibermesh parts will come into maya as curves, so it is a fairly simple procedure to have Maya use those imported curves as the basis for the nHair system. Shaun also takes a look at how to use the Fibermesh imports along with Joe Alter’s Shave and a Haircut hair system plugin for Maya.
