Most hairs made for poser figures are not dynamic hairs - they are layers of mesh with transparency mapping. The only DS dynamic hair solution I know of is the plugin "Look At My Hair", I do not know if it can export. Poser has its own in built dynamic hair solution, but not many people use it. There is also fibremesh hair as created in ZBrush, but thats pure geometry. Carrara also makes nice hair, but it's native use only.

I doubt many poser hair makers use those programs, but I don't know. I'm pretty sure that most make the mesh in their modeler like any other mesh.

Any rate - this thread is mostly about converting hairs from any figure to a specific figure, Roxie.
