Shadowartefact on hair (animation)

[stger]

Hey,

I have a strange artefact on a beared while doing an animation. There’s suddendly a shadow coming on the beared which looks like a clitch in the final animation.
I played around with samples an the light path max bounces to get rid of it, without any success.

Any hint/idea what I can do make the shadow not appearing so harsh?

The character is rotating to the camera (turntable, with fixed camera and lightning)

It would be very hard to tell what’s happening just from these few images. Could you show the render settings? Maybe post a higher resolution still image of the glitch?
