Remember to use the trigger word jeonsomi. You can use LORA weight 1 and Hires fix with latent bicubic antialiased, 20 steps, 0.4-0.6 denoising strength, and 1.25x upscale. Inpainting can help sometimes. Might need to negative prompt "blonde hair, pink hair" if you don't want it since most of the training images were on light colored hair Somi.
