Don't use scanline. Use either the rasterizer (might want to check out rasterize hair disposable) or raytracing (possibly with unified sampling).

Use Rasterizer.
Use hair primitives... not volume.

DON'T USE Saturation/Color/Gain variation.... all at 0.0. (Except for still images).
That's the biggest noise culprit I've found with the hair puppet shader.

It's mentioned in this tutorial. I did a test and discovered it to be true.

Note the section 2/3 of the way down:

Scene:

Possible reasons of fur flickering in animation:
1) mesh smooth node on maya fur geometry with smooth UV= ON, if so- turn it off.
2) flickering shadows- rize shadow map samples.
3) overal flichering - be sure in p_HairTK all variations (saturation, color, gain)= 0.
