as seen in the image the hair go right through the head, no matter what I did, even tried adding collision and rigid body, but nothing. How can I make dynamic hair collide with the emitter?

I have the same problem for days, I solved mine partially with enabling size deflect. It still go through the emitter but is less noticeable in my case. But I hope there’s a better solution out there.

Hi. You make sure to “apply scale” in your emitter. Select the emitter object, open N panel and on first tab in Transform item check that Scale=1 in all coordinates. If not, under Object menu, Apply and Scale.
