This is an attempt to port the "folded ponytail" tag from Illustrious (which is rock solid at it*) to Z-Image (which has no idea**). Since calling it by its Danbooru name would lead to collisions with actual ponytails, I've called it "folded updo" here.
Note: Since this has a considerable amount of anime-ish images in the dataset, you may have to prompt for realism/photography more explicitly than you're used to. Conversely, if you prompt for anime/illustration and not for the hairstyle, this actually works as a decent "generic anime" style LoRA.
* all Danbooru-based models are, likely thanks to Kaguya Shinomiya
** Same for Flux and Qwen, which I might make later. Chroma can do it already.
