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?"

Mode	Best For	Speed	Quality
max	Final results, client presentations, portfolio work	Slower	Highest
eco	Quick previews, trying multiple colors, concept exploration	Faster	Good

Multi-Turn Color Exploration

Use session_id to iterate and explore colors:

# Start with a base change
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Change my hair to copper red",
    "image_urls": ["https://example.com/selfie.jpg"],
    "session_id": "hair-exploration"
  }'

# Request adjustment
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Make it more auburn and less orange, add some brown lowlights",
    "session_id": "hair-exploration"
  }'

# Try a completely different direction
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Actually, let me see the original photo with silver gray hair instead",
    "session_id": "hair-exploration"
  }'

Error Handling
