What worked for me was messing with the LODs tab on the har asset. Like in this video:
I had the 3rd person camera right at the edge of LOD2 so it was constantly swapping. I changed the LOD2 to strands and everything was more smooth. LOD3 Is not reachable so the switch to cards is not really ever seen.
Kind of a workaround, but the strand to cards switch is really brutal as-is on an afro hair.
