A conformer will only conform correctly to the figure is was made for. To use it on a different figure you have two options that I can think of.

1. Save a copy of the hair geometry, positioned and scaled appropriately to the figure you want it to fit. Then create a conforming cr2 for it, based on the target cr2, and with all the geometry in the neck actor.

2. Assuming that you don't know how to do the above, the alternative is this. Load the hair but don't conform it. Parent the hair's Body actor to the head actor of the target figure. Of course with this method the hair is not conformed, and you will have to pose it manually. With some conforming hair, some of the actors and/or channels may be hidden, you may need to unhide them to gain full control over the hair (but hopefully you will not need to do that). Use scaling and magnets to make the hair fit the figure's head.
