Material Has Dark Areas that Move as Object Moves When Rendered

I’m rendering video of a tress of hair moving. The issue I’m having is that when rendered as the tress moves from side to side there are darker areas that seem to change when the tress moves. I don’t know if they are shadows or the actual material though. The top of the tress is also an orange-ish color

I’m also having an issue with the 3D view not looking like the material preview but I don’t have any light in my scene to cause this.

Attached are the material node, 3D view, and the final render.
