Best Practices

Getting Realistic Results

• Good Lighting: Use photos with clear, even lighting on the hair
• Hair Visibility: Ensure the hair is clearly visible and not obscured
• Face Forward: Front-facing or 3/4 angle photos work best
• High Resolution: Higher quality source images yield better results

Prompt Tips

1. Be Specific: Describe the exact shade you want (e.g., "warm honey blonde" vs just "blonde")
2. Reference Tones: Mention undertones (warm, cool, neutral, ashy, golden)
3. Texture Preservation: Request to maintain natural texture and shine
4. Realistic Expectations: Fantasy colors may look more vibrant on lighter base colors

Example Prompt Structure

"Change the hair to [specific color with undertones].
[Additional details about dimension, highlights, or effects].
Keep the hair looking [natural/healthy/shiny/textured]."

Mode Selection

"Do you want fast results or highest quality?"
