On the whole "Hair" issue. There are THREE types of hair. There are HR2 Prop Hairs which come in either 1)Dynamic or 2)Geometry formats that have Transmaps and textures applied and there are 3)CR2 Hair figures which are usually made for a specific figure.

Both of the HR2 prop formats are saved for one specific figure but simply adjusting them with the X, Y & Z translation & scale dials will bring them into alignment and scale them with any figures head that you have applied them to. HR2 Props do NOT Conform. They load pre-parented to the figures head and just have to be adjusted with either a fit pose or the X, Y & Z Translation dials.

CR2 hair, being a figure made for a specific figure can only be conformed to the figure it was created for. If you wish to use it on a figure that it wasn't created for, you do not conform it. You parent it to the head of the figure you're working on and adjust it with the translation dials as you would an HR2 prop hair. You won't usually find Hair Fit poses for CR2 hair.
