Quick proof of concept: I make a scalp mesh from a roundcube, grew 10 particle hairs out of it, and created a mesh with child hairs via HairTool (unfortunately a paid addon, but worth the cost IMO).
(There's a way to have hairtool generate hair from combed particle hair but I haven't mastered it yet...)
I compiled the hair as clothing on the "default" (caucasian) male mesh. I did a quick and careless job of converting it to clothes since it's just a proof of concept, so I'm uploading the obj here in case anyone else wants to play with it.
And if anyone has particle hair that they want converted to mesh, send the blend file to me and I might get around to converting it.
