Make sure you are aware on the usage instructions of LORA
Sampler: DPM++ SDE Karras (Recommended for best quality, you may try other samplers)
CFG Scale : 5 to 10
LORA weight for txt2img: reccomended 0.2-0.5.
Insutrctions
My advice is to start with posted images prompts then change them, in any case you will find different keywords for each model (wich should be used with a weight of 1.2-1.3).
Also in version description on the right you will find more details about each hairstyle model.
