Yes - your best option for hair highlights is with the anisotropic node. But it needs help and you need two of them.
You need two because hair produces a double highlight.
You need to help it because this node produces incorrect results at the "crown" - the very top of the head.
You should realize also that the anisotropic node is a poor simulation for light and only reacts to Poser lights, not to Poser scenery. It will not at all react to the sky, so it will not look right just with anisotropic nodes.
It will also be strongly disturbed by discontinuities in the mesh normals, so if your hair has few polygons, use subdivision to make the hair polygons bend really smoothly.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
