Dried Henna Black (Indigo tinctoria) can be used as a hair dye to achieve rich, dark hues. When applied correctly, indigo can impart a beautiful black or dark brown colour to the hair. Here's a guide on how to use it effectively, including considerations for pH and detailed instructions.
Preparing and Applying Indigo as a Hair Dye - Direct Application
Important considerations:
- Patch test: Always perform a patch test before using indigo to ensure you do not have any allergic reactions.
- Strand test: Conduct a strand test to see how your hair reacts to the dye and to determine the resulting colour before applying it to your entire head.
- pH level: The pH of the indigo mixture is crucial for dye release and effectiveness. Indigo releases its dye best in an alkaline environment.
- Consistency and coverage: Indigo tends to work best when used consistently over time. Multiple applications may be necessary to achieve the desired depth of colour.
- Natural dye interactions: Indigo is often used in combination with red henna (Lawsonia inermis) to achieve different shades of brown and black. Pure henna imparts a reddish-orange tint, which, when used with indigo, can create various shades of brown to black depending on the proportions and application method.
- Colour maintenance: Natural dyes like indigo may fade over time, so regular use of indigo-infused products can help maintain the colour.
Step-by-Step Guide to Applying Indigo Hair Dye
Materials:
- Dried Henna Black (Indigo tinctoria) powder
- Warm distilled water
- Baking soda (optional, to adjust pH)
- Mixing bowl and spoon
- Gloves
- Application brush
- Shower cap
- Towel (for protection against staining)
- Acidic rinse (e.g., diluted vinegar or lemon juice)
Instructions:
- Measure the indigo powder based on the length and thickness of your hair. Typically, 100 grams is sufficient for short hair, 200 grams for medium-length hair, and 300 grams for long hair.
- In a non-metallic bowl, mix the indigo powder with warm distilled water. Stir until you achieve a yogurt-like consistency.
- Optional: Add a small amount of baking soda (about 1/2 teaspoon per 100 grams of indigo powder) to slightly raise the pH, enhancing dye release.
- Wear gloves to avoid staining your hands.
- Protect your clothing and surrounding area with old towels or a protective cover.
- Section your hair to ensure even application.
- Using an application brush, apply the indigo paste generously to each section of your hair, starting from the roots and working your way to the tips.
- Ensure all hair strands are thoroughly coated with the indigo paste.
Processing time: Once the paste is applied, cover your hair with a shower cap to keep the paste moist and enhance dye absorption.
Leave the indigo paste on your hair for 1-2 hours. The longer you leave it, the darker the colour result.
Rinse and condition: After the processing time, rinse your hair thoroughly with warm water until the water runs clear. Avoid using shampoo immediately after rinsing to allow the colour to set. You can condition your hair if needed.
Acidic rinse: To help lock in the colour, perform an acidic rinse using diluted vinegar or lemon juice. Mix 1-2 tablespoons of vinegar or lemon juice with a cup of water and pour it over your hair. Leave it on for a few minutes, then rinse with water.
Tips for best results:
- Pre-treatment: For a more vibrant and lasting colour, consider pre-treating your hair with henna (Lawsonia inermis). Applying henna first will provide a good base for the indigo and result in a richer, darker colour.
- Colour maintenance: To maintain the colour, avoid frequent shampooing with harsh detergents. Use sulfate-free shampoos and conditioners.
- Hydration: Indigo can be slightly drying. Follow up with a deep conditioning treatment or hair oil to keep your hair moisturised.
- Using dried Henna Black (Indigo tinctoria) as a direct hair dye provides a natural and effective way to achieve beautiful, dark hair while maintaining the health and integrity of your hair. With proper preparation and application, you can enjoy the benefits of a chemical-free, vibrant hair colour.
How to Use Indigo in Natural Shampoos and Conditioners
Incorporating dried Henna Black (Indigo tinctoria) into your natural shampoos and conditioners can provide a gentle and effective way to enhance and maintain your hair colour while promoting overall hair health.
In Shampoos:
Indigo can be incorporated into natural shampoos to gradually colour the hair over time with regular use. However, due to the nature of indigo dye, it might not be as effective in shampoos compared to direct application, as the contact time with the hair is relatively short.
Basic Indigo Shampoo Recipe
Ingredients:
- 2 tablespoons of dried indigo powder
- 1 cup of natural shampoo base
- Optional: a few drops of essential oils for natural fragrance and benefits (e.g. lavender, rosemary)
Instructions:
- Add the indigo powder to the natural shampoo base and mix well until fully combined.
