Hi,
the main issue is that the head transform happens at the very top. I moved that all the way down and set up the guide deform SOP.
From you screenshot I see a resample SOP after guide deform - general rule of thumb, never resample animated guides. It'll resample differently on each frame and will destroy motion blur among other things.
You'll see that the scene is like 20x faster, even the simulation, because nodes only become time dependent at the very bottom, just before sim & hairgen.
