Looking at Inputs in hair_principled.rst, I think it's preferable to have subsections like Common, F82 Tint, and Physical Conductor, instead of mixing all the inputs.

Base Color
Color of the material when viewed straight on.
Edge Tint :guilabel:`F82 Tint Only`
Edge Tint
Color of the material when viewed at a 82° angle.

You could say "Refractive index per color channel. This is the real part of a complex refractive index, scientifically denoted as n".
Just saying Index of Refraction feels a bit messy when the IOR is complex. Also saying using base and edge color is just another model, mentioning it here sounds like the two models are connected, but they are not.

IOR :guilabel:`Physical Conductor Only`
The Index of Refraction (sometimes denoted by n) per color channel. Combined with *Extinction*, this controls the base
and edge color of the metallic material.
Physical Conductor

Similar here, I would prefer "Extinction coefficients per color channel. This is the imaginary part of a complex refractive index, scientifically denoted as k".

Extinction :guilabel:`Physical Conductor Only`

and edge color of the metallic material.
IOR
Refractive index per color channel. This is the real part of a complex refractive index,
scientifically denoted as n.
Extinction
Extinction coefficients per color channel. This is the imaginary part of a
complex refractive index, scientifically denoted as k.
Common
------
Roughness
Sharpness of the reflection; perfectly sharp at 0.0 and smoother with higher values.
