A patch test and strand test are essential before beginning any hair coloring process.
- Choose a small area behind your ear or inside the elbow.
- Gently wash the area with mild soap and water, then dry gently.
- Apply dye from the allergy test kit to a test patch.
- Place the patch onto the cleaned test area and press gently to ensure good contact.
- Leave it in place for 48 hours without touching or disturbing it.
How to Check for Reactions
✅ After 48 hours, remove the test patch.
✅ Wait 30 minutes, then check the area for reactions.
✅ Check again 24–48 hours later to see if a delayed reaction occurs.
Look for signs like:
- Redness
- Itching
- Swelling
- Rash or blisters
- Burning or stinging sensation
✅ If no irritation appears after both checks, it's safe to continue.
⚠️ If any reaction occurs, DO NOT use the product under any circumstances.
