It is not trained in the same way as the "hair height slider" lora, but is extracted and merged. I'm not sure which one is better, you can choose the one you feel comfortable with. Most of the time, it only has the function of modifying the shape of the head, reducing soft hair and preventing hair collapse. Make the top of the hair look more rounded, rather than like a bullet head. Sometimes it is possible to lower the overhead height, it happens randomly. I don't recommend weight going above 0.7, the noise will change too much. The recommended weight is 0.3, and if necessary, run it again with 0.5 in same seed.(The sample photos are deliberately selected, otherwise it would be difficult to observe)
