Flicker in Hair

[Guest]

I have a model with hair maked with Hair Farm. When I render a few renders from the animation, a noisy flicker shows in the hair. The other objects doesn't have flick, just the hair. Can anyone help me with that? I already played with Subdivs and Interp. Samples in the Irrandiance Map.

Is the flicker occuring on the edges of the hair? Might want to try upping the Min Subdivs. Also I think Irradiance Map will cause issues with Hair, Brute Force might work better.
