How to Use Henna for Natural Hair Colouring

Step 1 — Henna Application (Orange-Red Base)

  1. Mix Henna Powder with warm water (or warm black tea for deeper colour) to a smooth, lump-free paste — consistency of thick yoghurt
  2. Optional: add 1 teaspoon Nellikka (Amla) Powder for added conditioning
  3. Cover and rest the paste for 30–60 minutes (allows lawsone to release)
  4. Perform a strand test on a small section of hair — wait 24 hours before full application
  5. Apply paste evenly to hair from roots to tips using gloves
  6. Cover with a shower cap
  7. Leave for 1–3 hours (longer = deeper colour)
  8. Rinse thoroughly with water — do not shampoo immediately
  9. For orange-red result: stop here
  10. For dark brown / black result: proceed to Step 2 (Indigo application)

Step 2 — Neelamari Indigo Application (Dark Brown / Black)

  1. Mix Neelamari Indigo Powder with warm water to a smooth paste — use immediately (Indigo oxidises quickly)
  2. Apply Indigo paste to henna-treated hair immediately after rinsing Henna
  3. Cover with a shower cap
  4. Leave for 45–60 minutes
  5. Rinse thoroughly with water
  6. Avoid shampooing for 24–48 hours for best colour development
