The hair is too many grainy

Hi everybody!

I'm with a issue in the OOT Low Ponytail hair. It's too grainy for me.
I would like to know if the problem I'm facing is related to this specific hair, or if it's some adjustment I need to make and I'm doing it incorrectly. Even in a large amount of samplers, around 2500 in this example, it seems to have a lot of grains in the hair. In other hairs I haven't seen this behavior. In my render settings, I've been using the "Mitchell" filter with the pixel filter at 0.9, 1.0, and even 1.10, but the grains still appears. I also have the Firefly filter enabled. In the Environment, I set the Environment intensity to 1.10. I have 2 light sources, a key light with 550000.0 lumens, and a Rim light with 350000.0 lumens.
I would like to know if this problem is due to a lack or excess of light in my scene, a render setting or an issue with the hair asset.

* PS - In the red head hair you can see red dots, no matter the samplers number they still there.

Those 'grains' come from the Translucency and SSS settings on the surfaces of bangs, front, back and side hairs. You may set 0.1 to both of Transmitted Measurement Distance and Scattering Measurement Distance, or even zero Translucency Weight... More samples for rendering will also help ~
