Hair tags set length, styling, bangs and color: twintails, ponytail, braid, blunt bangs, flipped ends. They are the core of building an original character. 152 tags are listed for V4.5.
Place them right after the count: "1girl, solo, long hair, twintails, blunt bangs, black hair". With a character tag, add "alternate hairstyle".
Top-scoring hair tags.
V5 keeps stacked hair tags consistent and honors fine bangs detail; V4.5 shifts the look hard from a single tag.
The hairstyle won't change.
The character's default is winning. Add "alternate hairstyle" or raise the weight.
How do I set hair color?
"black hair", "silver hair"; "gradient hair" for gradients.
