Here you go, enjoy! This LoRA has two trigger words: 'tHairTls' for triangle ponytails and 'tHairShn' for triangle hair shine/highlights. This LoRA still needs more refinement, and I intend to perfect it in the future. I'm submitting it now as the deadline for this bounty is approaching.
To get the best results, I had to set the strength to 1.7. While it works, there are still some issues, including occasional inconsistencies. Using the terms 'triangle ponytails', 'triangle hair shine', 'triangle highlights', and specifying hair color seem to improve results.
