This hair mod works with a bug in Vanilla I experienced some time before, and that shows only the head of the girl (it doesn't need the Loader).
I wanted to use it in some way and finally found this stupid idea.
Nothing of the usual girl appears but her tongue (her eyes are hidden, and her skin is completely white due to the custom data).
Use this Custom Data to make the body disapear:
bodyScale:NaN;skinhsl:0,0,4,4Be careful! Her beak can perforate the stomach!
IMPORTANT: using this custom data bugs the game permanently. To go back to normal, load another character from the Scene tab and restart the game.
