Fuzz - Arnold User Guide
You should use the Sheen AOV to have Fuzz as an AOV.
Fuzz Weight
An energy-conserving fuzz layer that can be used to approximate microfiber, cloth-like surfaces such as velvet and satin of varying roughness, as well as dusty surfaces.
The fuzz is a volumetric layer of particles, whose shape is controlled by the roughness (fiber-like for low roughness, tending to spherical for high roughness). The Fuzz Weight can be thought of as the density of the volumetric layer of fuzz, layered on the substrate (base, and coat if present).
When increasing Fuzz Weight values, the density of the flakes changes, but their shape is constant.
As well as fabric, fuzz can be used to simulate dust, leaves, fruit, or the peach fuzz on a face (best when viewed from a distance).

Fuzz Color
The reflection color of the fuzz particles. Tints the color of the fuzz contribution.

Fuzz Roughness
The Fuzz is a volumetric layer of particles, where the Fuzz Roughness controls the shape of the particles, fiber-like for low roughness, tending to spherical for high roughness.
When increasing Fuzz Roughness values, the shape of the flakes changes (from fibers to spheres), but their density is constant.
At low roughness, the fibers scatter predominantly in the grazing direction producing edge highlights typical of high sheen cloth. At high roughness, the spherical grains scatter more isotropically, producing a more dusty appearance.
