no, it is a hair, as in what grows on the head, shader.  Valea makes transmapped hair.  it's a pretty basic shader with GC, 0.8 diffuse and anisotropic specular.  and some CoE.  the thing about testing it on regular textures, including Valea's, is that they have burned in specular. it's not the best comparison.

the thing that makes it different than your average bagginsbill GC shader is the specular is an anisotropic node colored a pale yellow, boosted to a Relectivity of 6, and given a U/V of 1, 0.1.

edited to add: you could write a Matmatic function for it in seconds.
