I have been trying hair dynamics in Blender 2.81. I am using a hair particle system on my mesh. I need the emitted hair to interact and collide with the mesh. Can someone tell me how to achieve this?

I am also struggling with this. Here you have some advice: How do I stop hair particles going through the body and the head? Hair dynamics works, but not perfectly. In faster speed of the object, some strands always will go trough the mesh. Also there is a bug in Blender 2.8. - When the quality step (hair dynamics) is above 1, hair explodes. So, don't use this verison if you want some collisions.
