How to Color Natural Hair with Henna and Indigo – A Comprehensive Guide

Henna and indigo are some of the best and safest ways to color natural hair without causing any damage.

Natural hair is resilient and versatile. You can do many creative things with natural hair.

Unfortunately, coloring natural hair with chemical dyes is not one of those creative things.

Irrespective of what the bottle says or promises, coloring natural hair with chemical dyes will eventually lead to dryness, split ends, and breakage.

The chemicals are just too harsh for the hair. They work by raising the pH level of hair and breaking down the structural bond of hair.

Henna for Hair

Henna is a plant that contains a red-orange pigment known as lawsone.

When an acidic agent is introduced into crushed henna leaves, it activates the lawsone molecules.

When the lawsone molecules are activated, it penetrates deep into the hair shaft and leaves a deep stain.

3 Myths About Henna for Hair

There are a few myths about henna, which I will disabuse before you dye your hair with henna and indigo:-

1. Henna Can Make Hair Grow Longer

Henna cannot make your hair grow longer or increase the hair growth rate. That is simply not possible.

It will improve the overall health and durability of your hair, which will lead to healthier hair growth, not long hair growth.

2. Henna Can Repair Split Ends

Henna cannot repair split ends. It can help you hold onto them longer than necessary but it cannot repair split ends.

The only thing that can end split ends is a merger between your hair and a good pair of trimming scissors such as Equinox Professional Razor Edge Series.

3. Henna Can Loosen Curl Pattern Significantly

This is unlikely. The next article will cover this myth in greater detail along with pictures of my experiment to test this theory.

Indigo for Hair

Indigo comes from a plant that can be found in tropical areas. This plant contains the rich blue dye used to dye hair.

Indigo can also be used to dye clothes and is applied over hair after a henna treatment.

This application leaves a lovely blue-black stain with red, orange, and brown undertones on natural hair. 

Henna and indigo make a perfect combination for dyeing hair.

Do not dye your hair with indigo alone unless you want to end up with flaming blue hair like Marge Simpson.

While indigo alone on black hair won’t turn it as blue as Marge’s, it won’t have the same rich, lush results as when combined with henna and will leave your hair dull.

Henna and Indigo Recipe for Dyeing Grey Hair

The recipe below is for dyeing grey hair as well as giving black hair a rich blue-black hue. You will need the following ingredients:-


  • 1 – 2 packets of organic henna like The Henna Guys Henna Powder. You may need more if you have long hair. You can freeze unused henna paste for later.
  • Bottled lemon juice. You may need up to 2 bottles of lemon juice.
  • Roll of Cling film
  • Gloves to protect your hands from staining
  • If you want a cooler undertone to the dye, consider adding 2 tablespoons of amla powder to the henna mix. 
  • 1 – 2 packets of indigo powder like The Henna Guys Indigo Powder. You may need more if you have long hair. You cannot freeze unused indigo paste so mix sparingly.
  • 1 – 2 packets of CMC powder. This powder makes the indigo mix creamier so it spreads easily and evenly through your hair.

Henna and Indigo Directions for Dyeing Grey Hair

  1. Mix the henna with enough lemon juice to form a smooth paste with the same consistency as chocolate mousse. If you plan to add amla powder, do not use lemon juice for this step. Lukewarm water is best.
  2. Cover with cling film and set aside for at least 24 hours before you plan to dye your hair. The longer you keep it aside, the more dye is released from the paste.
  3. When you’re ready to dye your hair, mix in enough lemon juice (water only if you’re using amla powder) with the paste to form a smooth runny consistency but not too runny.
  4. Apply some vaseline on and around your ears so the henna doesn’t stain.
  5. Slip on the disposable gloves then apply the henna mix to your hair and scalp generously. Don’t worry about applying too much. Saturate your hair with the henna mix.
  6. Wrap cling film around your head and leave it on for up to 8 hours. You can apply at night and leave it overnight.
  7. Rinse out with a cheapie conditioner like Garnier Fructis Pure Clean Conditioner, Alberto VO5 Moisture Milks Moisturizing Conditioner, or Suave Naturals Conditioner and water.
  8. When your hair is free of henna, pin up and mix your indigo paste.
  9. Mix 1 – 2 packets of indigo powder, 1 teaspoon of salt, and 1 packet of CMC powder with enough water to make a creamy consistency.
  10. Apply to hair the same way you applied the henna paste.
  11. Wrap cling film around your head and leave in for an hour minimum but you can leave it in for several hours more if you have the time.
  12. Rinse out with lukewarm water until your hair is clean.
  13. Follow with a deep conditioning session and style as usual. The blue-black color will get richer over the next few days.

Henna and Indigo Directions for Brown and Reddish Highlights

  • Mix the henna with enough lemon juice to form a smooth paste with the same consistency as chocolate mousse.
  • Set aside for at least 24 hours prior to dyeing your hair. (Water only if you’re using amla powder).
  • When you’re ready to use the paste, mix in enough lemon juice with the paste to form a smooth runny consistency but not too runny. Set aside.

  • Leave in for up to 8 hours. Rinse out with water and a cheapie conditioner afterward then follow up with a good deep conditioning session.

  1. I’ve been using henna alone, sometimes I may add lemon juice and I love the orange reddish color I get. Is there an additional benefit for me to use the indigo along with the henna other than achieving to the blue black color?
