The NURBS path method didn’t really work out for me, and obviously neither the realistic hair nor low-poly would work for my workflow/style. While being much harder, I tried various attempts at just modelling the hair as a mesh, it looks closer to what I want, but still pretty cumbersome to do, and still not perfect.
I’m currently wondering if there’s some stuff I haven’t found (maybe some plugin I don’t know of?).
Some update: After working a bit on my game engine (which is 2D instead of 3D rendered), I encountered this video: https://www.youtube.com/watch?v=JhPGUl7zPnc and it helped me a lot. Likely this method needs some refinement, but it’s immediately a lot easier to work with, than with the NURBS path.
