Is this correct?  There is no such thing as a "gamma" node.  You're renaming a math_function node as "gamma" then adding 1 or 2.2.

And if that's the case, is a Gamma "anti-correction" subtracting the same amount?

I assumed yes and followed these steps but the results make the hair loose it's assigned color.

Could you show us the updated set-up with gamma correction?
