I'm having issues with my hairs.

The first problem (is hard to see on the video), is that the hair itself keeps moving/jiggering entirely to the sides and sometimes rotate a little (the entire hair object). It's very suttle I don't know if you will be able to see it on the video, but ruins the experience.
video of problem 1 (I have disabled the hair scalp for this one):

The second problem is that the hair scalp keeps going inside of the head when playing any animation.
video of problem 2:

Hair configs (when I disable the cloth, none of these bugs happens... but I need the physics of course)
Any help will be appreciated.

The Scalp mesh is too close to the skin and it's causing Z-sorting issues.

Check the physX weightmap on the hair, if it's not completely black near the roots of the hair, it will cause be slight movement across the entire hair mesh.

You could use the Weight Mapper script to rebuild the PhysX coefficients, using a negative offset to push the weights down and/or increase the power of the curve to push the movement further down the hair.
