This embedding makes hair more stylish. The prompting for hair remains the same: color, length, braids, hairstyle, etc. The embedding adds a disheveled, perhaps slightly messy look. The characters no longer look freshly coiffed, but more like they've just done something more physical. 
The hair gets a color gradient that looks partly natural, but partly like the dye is growing out.

It was a crazy idea of ​​mine to try to do this with a Lora. I didn't know any better. The results with an Embedding are much better now with the few Gonzalomo checkpoints I used. I look forward to seeing your pictures and tests with other Checkpoints!
