You can use this wildcard to generate random dyed, balayge, ombre and natural hairstyles - if the model knows them.

This dynamic prompt picks a random hairstyle without adding a haircolor:

__lin_mc_hair/prompt-hair__

This dynamic prompt picks a random hairstyle with a random natural haircolor:

__lin_mc_hair/color__ __lin_mc_hair/prompt-hair__

This dynamic prompt picks a random hairstyle with a random dyed haircolor:

__lin_mc_hair/prompt-dye__

This dynamic prompt picks a random hairstyle with a random balayage haircolor:

__lin_mc_hair/prompt-balayage__

Balayage is a professional hair color technique that creates a subtle highlight effect in a different color.

This dynamic prompt picks a random hairstyle with a random ombre haircolor:

__lin_mc_hair/prompt-ombre__

Ombre is a gradient color effect where hair is split into two contrasting color sections and gradually blended.

You can edit the YAML file in Notepad++ or Visual Studio Code.

Add your own favorite hairstyles to the list and call them with the prompt:

__lin_mc_hair/prompt-fav__

You can combine the lin_mc_hair and lin_mc_origin wildcards to create random characters.

Feel free to edit this file and adjust it to fit your needs.

Known limitations:

Most models do not seem to make a noticeable difference between balayage and ombre.

In general this wildcard sticks better to the prompt with SDXL compared to Pony.

I use this wildcard to test the results and then add those styles that do work to the favorites.

cheers, lin
