I just checked: in 2013, I bought AmyHair from LittleFox and it's the one I've show here.
Starting with Poser11, you will find it in the included content, with a slight difference in the character's hierarchy, because yes: in both case: it's a conforming character, not a dynamic hair prop (dynamic au sens de Poser), so you may manipulate its morphs from the Pose and the Material rooms, it has nothing to do with the Hair room.

Here is the Poser13 version:

And LittleFox version:

Note that LittleFox used to sold a set with 3 versions: Aiko3, Vic3 and Vic4.
The one that comes with Poser's content package snaps directly in place with Pauline2 fox example:

That probably explains why its body structure is somewhat different from version of LittleFox.
