Hi Franken,
If I understand correctly, you are traying to generate hairs from tubes or polygon strips? If so, you can use the HairFromMeshstrips node. This allows you to create hairs following the edge flow of the tubes or polygon planes/strips. We have a two parts tutorial about this workflow:

If you are traying to instance mesh objects in a hair object just like in the video you linked, you can use the MeshFromStrands node and import some proxy meshes into this node, then work with the instanced meshes as if they were hairs. We also have a tutorial about this workflow (It's from an old version of Ornatrix but still applies):

And a lot more information and examples in our documentation HERE. Let me know if you have further questions.
