However the hair is intended for V4, and has no S4 support as such. It appears to fit after using the scale transfer script in Poser 7, but on closer examination there's a weird crumple zone which puts a new slant on the term "bad hair day". :)

In Poser 9, as suggested, the hair doesn't take up the right scale at all and she ends up with a bald spot. :(

I think it may be safer to use V4 for this project.
