Anyone implemented ,Marschner hair shading?

If I remember well the NVIDIA Nalu demo presented in GPU Gems 2 contains an implementation. So you might want to check that out.

It does not do a lot of good for the understanding though. So if you're interested in that you might want to go through the paper and derive some formulas yourself.

I can think of at least two people who regularly hang around who did or, at least, were involved in doing, but both did so for work, so they might not be at liberty to talk about it.
Said that, it might help to know what platform you want to implement it for, and where you got with your efforts, or what the stumbling blocks were, if you tried anything on your own.

Asking how to implement something from scratch without any specific questions is akin to asking for a full tutorial about it, which nobody who can provide a decent one has time to do.
More focused questions might get you more attention.
