generates extremely long hair,

V1

Use sprlghr, hair on floor, very long hair as triggers

V2

Use toomuchhair, very long hair, absurdly long hair as triggers

V3

Combined the datasets of V1 and V2. Also removed uncommon tags from the training set. This should be more versatile and give better prompt control than V1 or V2

Very Long Hair

gets you hair that touches the floor, or more typically body length hair

Absurdly long hair

gets you hair that is starting to or is mostly filling a room or space

Illustrious V4 & Anima V1

reused the dataset from V3. Adjusted training parameters to better target the hair. Seems to be less likely to blend the hair with clothing. The same tags apply from V3, see above
