OK But is the Poser standard .Hr2 different from Prop Hair?

I have many .Hr2 hair items and few hair items in the .Pp2 format. .Hr2 seem to have more motion and style morphs whereas the .Pp2 format have bqrely any and both are able to work with ALL figures with just a little bit of positioning. I do use the .Cr2 hairs on many figures besides wthose they are meant to conform to but if the have say pony tails that have motion or position morhs it pulls the hair crown off the head if merely parented.

Is the .obj that Daz says it includes with its hair items (normally conforming or .Cr2), then a Hair Prop or .Hr2 or is the .obj included just the seed for the .Cr2 hair you purchase?

I am still not sure why hair products need to be made as conformers when as .Hr2 items can be used with ALL figures and creatures and animals.
