Product Description

Synthetic hair colours ARE worrisome. They have been implicated in a whole host of disorders including non-Hodgkins lymphoma, bladder cancer, rheumatoid arthritis, contact dermatitis and accelerated development of cataracts. Even if you have experienced none of the above, what you would have experienced is dry, rough and damaged hair with high hairfall and poor hair growth with repeated hair colouring.

Issues with chemical hair dyes

Krya’s natural hair colour – midnight black is a semi permanent shade of dark indigo hair dye. The  colour gradually fades anytime between 2 – 4 weeks depending upon how fast your hair grows and the frequency of hair washing.


This organic indigo hair dye is formulated with Indigo, Henna and other herbs which bind naturally to your hair. Repeated colouring deepens the colour further, giving better coverage and a richer shade.

Every herb used in the Krya natural colour range is documented for hair use in the Ayurvedic texts. The product is therefore completely natural, completely safe and can be used even during pregnancy or breastfeeding.


Important: Every person reacts differently to a given set of ingredients, even completely natural ingredients like ours.  Please follow the precautions listed in “How to use” tab before every use of the Krya natural hair colour product.


Shade variations when using an organic indigo hair dye:

Synthetic hair dyes give you an even shade by first bleaching out all existing colour from your hair and then adding the synthetic colour to your hair. This is why the colour you get after a synthetic hair colour / dye is even and the same shade is present throughout your hair.


Any natural hair colour simply coats your existing hair externally with the shade you have chosen. The dye uptake from your organic indigo hair dye varies depending upon the grey percentage in your hair and how your individual hair strands react to the herbs in the hair colour.


So while we have tested the hair colour on human hair swatches, you can expect variations in the colour on your hair. We do not expect these variations to be too different from the hair colour we have achieved. Also, depending upon the grey percentage in your hair, you can see variations in the colour across your hair. Grey hair usually is much more intensely coloured and visible – black or dark hair tends to take on the colour much like highlights or tints. These variations even out over repeated hair colouring.


Features & Benefits of Krya Midnight black – a dark Indigo hair dye


Developed by us in-house over a year’s testing, this all natural , whole herb based Indigo hair dye uses safe Ayurvedic herbs to give your hair a rich, natural black shade without the side effects. Krya’s natural hair colour is a semi permanent shade that dyes the hair cuticle and does not penetrate the hair shaft or the cortex. Our testing indicates that the colour gradually fades anytime between 2 – 4 weeks depending upon how fast your hair grows and the frequency of hair washing.

Repeated colouring with this hair dye deepens your colour giving it a rich shade.


How do we make this natural hair colour

At Krya, we source high quality organically grown or forest-collected ayurvedic herbs from high quality organic farms, small farm cooperatives.

We clean, and shade dry each herb until it reaches the right level of dryness so it can e further processed. Then we process each herb singly. Indigo leaf is notoriously difficult to process. The plant has small thorny spikes between each leaf which stings skin when we clean and process it . (This is not present after we finish processing it). We repeatedly grind and sift Indigo leaf using an extremely fine mesh, to give organic indigo powder which releases dye pigments easily and quickly.

We singly process each herb in the Krya Midnight Black colour and sift it until they reach a similar particle size. Each herb powder is then carefully blended together before being weighed and individually packed.


Free from synthetics & Metallic salts:

As with all Krya products, the Krya hair colours are also synthetics free – the Krya hair colour range contains ONLY Ayurvedic herbs. They do not contain PPD, Ammonia, Resorcinol, tetrahydro-6-nitroquinoxaline, Eugenol, Coal Tar, Formaldehyde, DMDM Hydantoin, Eugenol, or ANY SYNTHETIC CHEMICAL.


Krya’s hair colours are also free from metallic salts and contain only hand-picked, sorted, sun dried and carefully processed Ayurvedic herbs. We process our herbs from scratch, choosing only the best quality materials. The formulations have been developed in-house after rigorous testing done over a year on human hair swatches, in-house volunteers and an independent consumer panel.

  • Safe & natural to use even by pregnant women and breast feeding mothers
  • Does not harm skin or trigger strong allergic reactions
  • Uses only 100% natural ayurevdic hair care herbs

Preparing your hair for colour:

The Krya Single Step Indigo based Hair Colour should be applied only on clean, washed hair . Prep your hair on the day of application, first , oil & wash your hair with the correct Krya hair care products .

Using gentle natural hair products like ours will ensure that the hair is clean and smooth for natural dye appliation. After dye application it also helps maintain the colour longer.

Mixing the Indigo hair dye correctly:

Make a thick paste of the Krya single step Indigo based hair colour in water.  Mix until you get a smooth, lump free, non drippy paste.

A good Indigo based hair dye will start releasing dye pigments within 20 minutes of mixing with water. you should see an iridescent colour pattern forming with prominent blue purple shade

Applying the Indigo Hair dye correctly:

Apply within 20 minutes of mixing the colour, apply hair colour paste thoroughly on hair , section by section. Use a Dye brush to colour your hair as the dye will stain skin.

Apply the colour paste as a thick coating onto hair. Use a thicker coating on small fine baby hair and greys. Ensure you spread and section the hair as much as possible for better grey coverage.

Waiting for the Hair dye to colour hair:

After completely covering the hair with the hair colour paste, leave it on for 1-2 hours. Wrap the hair with a shower cap and ensure you sit in a draught free environment. Avoid sitting with the AC on or in a windy place at this time.

For the colour to latch properly onto hair, the colour paste has to be moist for as long as possible. Therefore if you leave your hair uncovered, or sit in a windy place or in the AC, it can dry out the moisture in the colour paste interfering with the dye process.

At the end of 2 hours, mix the Krya creamy colour-strengthening mask and keep it ready for the next part of the process.

Rinsing out the Natural hair colour

After 2 hours, rinse out the colour paste thoroughly from hair using plain water at room temperature. Make sure you work the scalp thoroughly to remove any remnants of the paste. Use only room temperature water to clean the hair and scalp.

Applying the Krya colour strengthening Hair mask:

After thoroughly working the scalp and rinsing out the hair colour paste, apply the Krya colour-strengthening hair mask. This product helps bond the colour pigments better onto hir, cleans the scalp and smoothens and naturally conditions hair.  Apply in sections on the hair (follow the package instructions). Leave it on the hair for 30 minutes.

After 30 minutes rinse out this mask thoroughly from hair.  The Krya hair colouring process is now complete and you can dry your hair.

The colour will take 1-2 days to fully develop, as the herbs go through an oxidation process after application.



Complete List of Ingredients

How much product should I buy to colour my hair?
– Short hair -chin length – 50- 75 gm
– Medium length – Shoulder level or slightly below – 75 – 100 gm
– Long length – Waist or hip level length – 125 – 150 gm or slightly more if hair is thick

I used this product , but I got a very faint colour. What should I do ?
Henna and Indigo based dyes latch onto hair’s outer cuticle. Hence if there is damage in thsi area, you may get a faint colour or colour may wash off more easily. Please incporrate a good hair care routine for damaged hair and oil your hair well regularly to cover cuticular damage and improve har quality fo new hair. As you work on your hair, the colour experience will get better.

I used this product and I am happy with the colour I got. But it fades very quickly and I have to reapply within 2-3 weeks. what should I do?
We observe quicker colour fade in natural colours if the hair is not oiled regularly and when synthetic shampoos are used. Synthetic shampos quickly fade the colour which is latched onto the hair’s cuticle. Therefore you need to protect your natural hair colour better. Here are some ways to do this:

1. Use the Colour strengthening mask after every colour application. the product is specially formulated to improve colour latch as soon as dye is applied
Oil your scalp regularly atleast 2-3 times a week. Leave it on without washing. This helps heal any scalp damage and improves new hair quality and growth

2. Meticulously oil your hair strands 1 hour before hair wash. This oiling helps seal any breaks in the cuticle and also creates a protective coating around the hair. This protects hair integrity and also ensure colour fades less quickly.

3. Switch to a purely natural ayurvedic hair wash powder. We have a wide range fo options you can choose from. As the surfactant level is much less and as we use ayurvedic herbs in the formulation, it reduces colour fade.

I have very stubborn greys. I find that it takes many application to get a good strong colour. What should I do?
Grey hair or completely white hair is often dye resistant and it could take a while to get good coverage with a natural hair colour. If you are noticing that your greys are dye resistant, we suggest the following:

Alternate application of our Indigo based hair colour with our Henna based hair colours like Truffle Brown or Madyantika Uno. Layering Henna with Indigo and other herbs help improve the dye bonding and increases colour richness.

Ensure you follow the other steps listed above like oiling your hair regularly, oiling hair strands one hour before wash and switching to an ayurvedic hair wash powder
If none of these work, switch to our 2 step colour Dwii. This is designed to provide better colour latching for stubborn greys.

How to mix the indigo hair dye?

We’ve answered this question in detail in our “how to use” tab below.

What colour is indigo hair dye?

Depending upon what herbs are mixed along with Indigo, we can get varying shades from brown colour to black. On its own Indigo gives a purplish blue shade. It does not latch onto hair without the presence of herbs like Henna, so Indigo alone will not work as a natural hair dye.

Is indigo permanent hair color?

Indigo gives a semi-permanent shade when used along with Herbs like Henna, Amla, Khadira, Manjishta etc. It gradually fades over time with every wash and needs to be reapplied.

How to make indigo hair dye last longer?

Natural dyes fade faster compared to chemical dyes as they deposit on the surface of hair. To retain clour longer, we suggest oiling the hair regularly, and avoiding any practices that damages the hair cuticle like using heat, chemical shampoos, brushes and blow drying hair regularly.

Is indigo dye good for hair?

This combination of herbs we make the Krya hair colours with is good for hair.

How long should i leave indigo dye on my hair?

Indigo dyes can be left on for 1 – 2 hours on the hair. Leaving an indigo based hair colour is not recommended overnight.

Can you use indigo alone to dye hair?

Indigo alone cannot be used on hair as it does not bind properly to the dye receptors in hair. Henna and herbs like Amla, Manjishta and Khadira are needed to bond with Indigo and help transfer its dyeing molecules onto hair.

Can indigo dye hair blue?

Indigo dye has a blueish purple colour. It needs herbs like Henna to bind well to hair. When we add these herbs they bring down the pruplish tones of indigo. When these dye pigments attach to hair and coat it you might at best get a shade of black with purple or blue tint . But you will not get a blue hair colour.

How to apply indigo hair dye?

We’ve answered this question in detail in our “how to use” tab below.

Is indigo hair dye safe for pregnancy?

The Krya hair colour range is extremely safe for pregnant and breastfeeding moms. However please read the next point aout rashes and allergic reactions. Please do a pach test before usig our rpoduct or any Indigo hair dye.

Is indigo hair dye safe to use?

5% of the population have a natural allergy towards Indigo. This reaction is lesser in blended products like what Krya makes as we use a variety of herbs along with Indigo. But to be safe and rule this out, we recomed always doing a patch test before using any Indigo based hair dye.

Can I use Henna and Indigo powder on chemically treated hair?

Yes absolultely. However, it may take a while before you see good results as typically chemically treated hair is damaged and the cuticular structure has many gaps. As Henna and Indigo powder are semi permanent natural dyes that attach to the outer cuticular surface of hair, if there is damage in this part, the colour will not latch on properly.

Can I use Indigo Hair Dye to colour hair black without Henna?

This has already been answered above. It is not possible to achieve a stable hair colour without Henna and other herbs, using Indigo powder alone.

Does it help to treat grey and white hairs ?

Indigo and other herbs are excellent to provide a natural dark coverage to grey and white hair. However premature greying is linked to aggravated Pitta dosha in the body. To work on this, we suggest following a pitta balancing diet and using our Pitta balancing hair care range .

 How much organic indigo powder do you need to dye your hair?

This depends upon the natural length of your hir. For short hair, half of our standard package (100 gm) is sufficient . For medium or very thick medium hair, you may need a little over 100 gm. For long hair, 200 gm pack is required.

Is it better to use a natural hair dye?

Yes! Chemical dyes are notorously bad for health and their long term use has been implicated in many worrying serious health conditions. They have a strong allergic potential and can trigger many symptoms like skin disorders, serious difficulty in breathing, skin allergies etc. They also impair hair growth over time and damage the scalp. Pleae read more about this here and here.

Is it suitable for a 16 year old boy for grey hair ?

Yes. Please ensure a patch test is done before use.

Is the Krya natural hair dye range chemical free ?

Yes!! Every single product we make at Krya is 100% natural and 100% chemical free. We declare 100% of the ingredients that go into every product we make. Please check the “Ingredients” tab to know what goes into each Krya hair colour.

Many people who have suffered PPD based allergic reaction after usng chemical hair dyes use Krya’s range of natural hair colour. Some customers come to us after recommendation from their Doctors too.

    I think I need help with using it. I applied it as per instructions, but the grey still remains largely the same, in some places there is some mild change of colour. So, should I be applying more, or leaving it on for more time, or something else, I am not sure.
