Hi, this is a model for detecting wavy hair. I've only tested and trained it on anime images, so I don't know if it will work well with realistic images.

To change the blonde hair to black, I set like this:

positive: anime style, (black hair:1.8), high detail, dark color, long_curly_black hair, parted hair, messy hair, kinky curls,

negative: orange hair, red hair, blonde hair, blurry, face, person, distorted, green hair, body, lazyneg2, 3d, blurry, monochrome, greyscale,

Inpaint denoising strength:0.75
