Coloration naturelle au henné

Color your hair in a lasting way and benefit from incomparable shine, volume and care thanks to vegetable dyes. Only thanks to the force of nature.

We offer 2 major brands of vegetable hair colors in our shop: the Khadi® brand and the very young Emblica® brand developed by Bleu Vert. Color and care for your hair with truly natural color pigments and active ingredients. All these vegetable colorings are controlled at the level of harmful ingredients and undergo regular and strict controls in competent and independent laboratories.

None of these vegetable colorings contain preservatives, dye enhancers, peroxide or other chemical additives, because your health and safety is at the heart of the concerns of the Khadi and Bleu Vert laboratories.

Thanks to a particularly careful preparation and a superior quality, these vegetable colorings color with more intensity than all the vegetable colorings you have known so far. Take this into account when you apply these vegetable colors for the first time.

The difference between a chemical coloring and a vegetable coloring

Découvrir notre gamme colorations naturelles bio

A chemical coloring opens the scales of the hair, penetrates the hair fiber and bleaches them by peroxidation. The natural color disappears, the hair is depigmented and lightens until it even becomes completely white. Then, a succession of chemical reactions takes place inside the hair fibre: this is called re-pigmentation. It is this step that gives the new color to the hair. This method is aggressive because the hair must lose its structure to allow the chemical reaction to take place. He is denatured. In the case of repeated chemical coloring, the scales of the hair close less and less well. The hair is then weakened. It has a dark and dull appearance. The hair becomes dry, porous and brittle.

Unlike chemical coloring, vegetable coloring does not penetrate the hair fiber. Plant dyes are natural pigments that are extracted from different plants in nature. These pigments have a natural affinity for the keratin which makes up the hair and adhere firmly to the hair fibre. The color does not penetrate inside the hair. She sheaths and coats him. The structure of the fiber therefore remains intact. In the long term, vegetable colors become real treatments that improve hair quality. The more you do, the thicker and stronger the hair. It becomes more consistent to the touch and a feeling of volume appears. The hair, thus wrapped, is more resistant to stress and pollution. As vegetable coloring is softer than chemical coloring, the exposure time is a little longer. But as everyone knows...everything good takes time. The result is well worth the time. After a vegetable color, the hair is colored, cared for and respected.

Khadi and Emblica hair colors combine with natural hair color. This is why the results differ from person to person. The more the hair is colored with these colours, the more intense and long-lasting the tint.

How do Khadi and Emblica plant-based hair colors color ?

Coloration naturelle

These vegetable colorings tint your hair in a durable way (except the Senna / Cassia shade for Khadi®). It is for this reason that we advise you, before the first application, to do a coloring test with a lock of hair, to avoid any undesirable color results.

For more information on this point, refer to the paragraph devoted to this subject: “Before application, do a coloring test on a lock of hair! »

The vegetable colorings coat each hair like a stain. This means that the result of the color depends mainly on your original color, which thus gives rise to unique and personalized reflections. Several successive applications intensify your color.

With vegetable dyes, however, it is impossible to lighten the color of your hair.

In order to color the roots of your hair with the same intensity as your lengths, we recommend that you color your roots with the chosen tone. Since your lengths are already colored, it is possible that they will be more intense in the long run than at the root, which will have been colored less often.


You can safely mix together all vegetable colorings. The mixtures will depend on the desired result, but also on your hair type and your original color.

As we can distinguish with the naked eye different types of hair, likewise, each hair can present a specific structure. There is straight and fine hair but also frizzy, curly, wavy hair and many more. The hair can be fine, normal or thick, healthy and shiny but also very damaged. Along with the natural characteristics of the hair, the type of care your hair has received so far is also essential. Hair that has undergone chemical treatment, especially bleached hair, is generally very damaged, dry and brittle. Damaged, split ends require special care.

Thus, damaged hair, possibly having undergone chemical treatment and (or) fine hair will be colored more intensely than, for example, healthy and vigorous hair. If you doubt your hair type and its possible color hold, it is recommended that you, following a coloring test on a lock, start with a shorter exposure time, as you are used to with the vegetable coloring that you have used so far.

Before application: do a coloring test on a lock of hair !

In order to avoid undesirable results, we recommend that you do a coloring test on a few strands of hair, in particular before the first application of Khadi® vegetable dyes.

For this, the trick is to collect enough hair on your brush and apply a small amount of vegetable coloring diluted in water.

Place this colored wick in a warm place. We recommend that you test different exposure times and remove the color from the locks after 30, 60, 90 and 120 minutes. Rinse the locks with lukewarm water carefully. Wait before applying Khadi® vegetable coloring to your hair for at least 24 to 48 hours to be able to assess how the color evolves on your hair. The vegetable colorings can possibly be reinforced during this time under the influence of the air.

The necessary equipment for your plant coloring

Here are the accessories we recommend you gather for your coloring :

  • A sufficiently large bowl
  • Hot water
  • Gloves to protect your hands (provided in the box)
  • An old towel to protect your clothes
  • A brush for vegetable colors
  • A charlotte (included in the box)
  • A towel or woolen hat to keep the coloring warm

The optimal preparation of your hair

First wash your hair with the shampoo suitable for your hair type. Note that many conventional commercial products contain silicones. The silicone is deposited on each hair like a film and the hair initially appears shinier and healthier. But, over time, the hair is really sheathed in silicone and is no longer able to receive care products or colorings because it acts as a barrier to color taking in the case of vegetable colorings. For this reason, be sure to use silicone-free products before applying Khadi or Emblica herbal hair colors.

If we are not sure that your hair care contains silicone, we recommend that you wash your hair with ghassoul, for example, before applying Khadi or Emblica vegetable coloring.

Prepared in this way, your hair will take on the color optimally. The ideal is to apply the vegetable coloring to damp hair, in order to guarantee an even distribution of the coloring.

Mix vegetable coloring

Mix the necessary quantity of powder with water heated to 50°C to form a smooth paste (for medium-length hair, count 80 g to 100 g of powder).

Recommended dosage: 50 g of powder for 200 ml of hot water.

Be careful not to breathe in powder particles!

Tip: At Khadi, with the Henna Pur Red and Henna, Amla and Jatropha Red shades, we recommend diluting them in very hot water, as these shades color the hair more intensely. Never apply a hot paste, so as not to damage your scalp by the heat.

Apply plant color

Coloration naturelle

Remember to protect your textiles as it is difficult, if not impossible, to remove stains. Likewise, we recommend that you always wear the gloves attached to the coloring, because the shades are very tenacious, especially on the nails.

Apply the paste as hot as possible line by line, ideally with a brush intended for coloring. Start with the root and continue on the lengths line by line.

Distribute the rest of the paste on the hair, massaging with the fingers. This will ensure an even result on your hair.

After applying the vegetable coloring, put on a plastic cap to keep the coloring warm. Be sure to cover the temples and neck well. The coloring should never dry out.

To maintain the heat, you can form a turban on your head with a towel (you can also put on a woolen cap, for example, which also helps to maintain the heat or install yourself under an electric heat helmet).

The longer you keep the dough in the heat, the more intense the result will be.

Exposure time of a natural color

As indicated above, the exposure time of your vegetable coloring depends on the desired result as well as your hair type.

For the first application, leave the paste on for 30 minutes.

After coloring – how to achieve optimal hold ?

When the exposure time has elapsed, rinse your hair with lukewarm water until all color residue has disappeared and until the water runs clear. Khadi and Emblica plant-based hair colors rinse out easily with just water.

If possible, avoid washing your hair with shampoo or using styling products within 24 hours of coloring so that the color sets better on the hair.

The next day, you can easily wash your hair with shampoo.

By applying one of our hair oils you will contribute to better color retention.

Massage your hair and scalp with a small amount of oil the day after coloring and leave on for at least an hour (ideally overnight). Then wash your hair as usual with shampoo.

Note that the color may possibly still darken a little.

If you are not satisfied with the result, opt for a longer or shorter exposure time during the next color application, or mix the vegetable colors together. There are no limits to your imagination.

Tips for optimal care – what you can add to your herbal hair color mix

Particularly damaged hair has, in rare cases, a tendency, at first, to dry out under the influence of vegetable colorings. This effect is due to the astringent action of vegetable colorings. You can compensate for this effect, for example, by introducing a little silicone-free hair mask or conditioner into your paste.

Decrease the amount of water in your plant hair color in favor of 1 to 2 teaspoons of quality hair care.

But avoid oils, or products that are very high in oils, as they can prevent color from setting.

Root coloring

As we mentioned before, it is very likely that your lengths will color darker than at the root after several colorings, since the root has received fewer layers than the rest of the hair. In order to avoid this color difference, it is recommended to color only the roots.

Proceed with the preparations exactly as if you were coloring all of your hair.

Separate your hair now into several parts that you will hold with clips. Proceed step by step in the different areas while removing the clips and applying the plant color line by line only on the first centimeters of the root.

If you have an old application bottle, you can make the plant color a little more fluid and refill your bottle. You may need to widen the spout of the bottle a little to make it easier to squeeze the paste out of the bottle.

Again, the exposure time depends on the desired result and the structure of your hair.

Special advice in case of gray hair

When applying plant-based hair color particularly rich in indigo (this is the case for the Dark Brown, Black or Pure Indigo shades for the Khadi brand, but also Iced Chestnut 4.1, Deep Dark Chestnut 3.0, Iced Brown 2.1 and Deep Black 1.0 for the Emblica brand), white hair can pick up green or blue highlights. This is why these shades should not be applied directly to your white hair, in order to avoid unwanted color results. It should be noted that these color transfers are more rare with the Dark Brown Khadi® vegetable coloring. For greater security, we recommend that you carry out a test on a lock of hair.

It is also possible to color your white or blond hair in these shades thanks to 2-step coloring, as we will see in the next paragraph.

White hair: coloring in 2 steps

The Khadi and Emblica vegetable colorings are applied like a stain around each hair. This means on the one hand that the color result is essentially determined by your natural hair color and on the other hand that there can also be a big difference in color between your white hair and your pigmented hair.

The Henna Pure Red vegetable coloring for Khadi and Auburn Chestnut 4.4 for Emblica have the property of adhering very easily to the hair, while the Indigo Pur vegetable coloring at Khadi adheres less easily. This means that the indigo contained in the vegetable coloring mixtures fades faster than the red pigment. White hair can then fade very quickly, while other hair can darken more. This can cause unwanted contrasts.

In order to minimize this effect, it is therefore recommended to color in 2 stages, especially if you have chosen a very dark shade. In this way, the indigo will adhere better to your hair and you will obtain a better hold, including on white hair.

First, color your hair as indicated with the products Henna Pur Red or Henna, Amla and Jatropha Red for the Khadi brand and Auburn Chestnut 4.4 for Emblica. The exposure time will depend on your hair structure, especially the thickness of your hair.

On the now pre-colored white hair, you can now color your hair with the darker shades and thus achieve an even result.

Specific advice for the application of Senna / Cassia Khadi®

The application of Senna / Cassia Khadi® is the subject of specific advice.

Senna / Cassia Khadi® is a non-coloring hair care product that can be applied to all hair types.

Mix the powder like the vegetable colorings and apply it in the same way.

In the case of healthy hair, there is no need to pay attention to a particular exposure time, insofar as Senna / Cassia does not color the hair.

In rare cases, light and/or bleached and very damaged hair may take on a slight greenish tint, especially if you leave the treatment on for longer. For this reason, we recommend that you do a test on a strand of hair.

Answers to Frequently Asked Questions (FAQ)

Does plant color fade ?

Answer : In principle, in the case of vegetable colorings, these are permanent shades. Indeed, the coloring does not penetrate the hair fiber. This means that the color pigments are only deposited on the outer part of the hair. The red tones in particular are very stubborn and only fade over time. The staying power of the color will depend on how often you have already colored your hair with vegetable dyes.

Shades with a high percentage of indigo fade a little faster.

How long should I wait between 2 colorings ?

Answer : No need for a waiting time between two colorations. But note that the coloring can still evolve between 24 and 48 hours after application. If you are not completely satisfied with the result, respect this waiting time and then judge whether another coloring is necessary.

Is an application of vegetable coloring possible on permed hair ?

Answer : You can safely apply herbal hair colors even on permed hair. You will notice the caring effect of the coloring on hair damaged by chemicals. Even if you're doing a perm applied to hair that has been colored with vegetable hair color it's not a problem - although it may happen that it doesn't hold as well and it is necessary to extend the time of laid. However, we recommend that you go to a hairdressing salon where competent professionals, trained in vegetable colorings, have acquired a good knowledge of vegetable colorings.

Can we develop intolerances, allergies by applying vegetable colorings ?

Answer : Yes, even with vegetable colorings, you can develop intolerances and allergies. Unfortunately, almost any natural or synthetic component can cause a reaction. If you suspect an intolerance, for example because you generally have a very allergenic background, you should carry out an allergy test with your dermatologist. You can also carry out your own test yourself, by applying a small amount of diluted vegetable coloring to an inconspicuous area of ​​your hair. Leave it on for a maximum of 48 hours. Be careful though, because small amounts of coloring paste can color intensely.

Can I safely mix all shades together ?

Answer : All plant hair colors are safe to mix together, allowing you to create the personal and specific shade you want. There are no limits to your imagination. If you're not one to take risks, test your shade blends on strands of hair first.

The color has become too red, too dark – what can I do ?

Answer : It is essential to remember that vegetable colorings, due to their exceptionally superior quality, have a strong coloring power and that we can never advise enough to do tests on locks of hair. But if this happens and your hair has taken on too intense a tint, you have several options:

In the case of too red shades, you can proceed to a new coloring with one of the vegetable colorings in the palette of browns. In this case, be sure to observe a very short exposure time so as not to darken your hair excessively (test on a lock of hair!).

If your color turns out to be too dark, it will already be more difficult to lighten your hair color by one or two tones. In this case, you have to be patient. Since the indigo part (which allows you to darken) in the vegetable coloring mixtures fades a little faster than the henna part (which allows you to color in red), your color will fade over time. It will eventually take on a redder tint.

Other methods consist of applying regular hair care with exposure times much longer than the usual exposure times, including at night. A mixture of honey, olive oil and lemon juice can also slightly lighten your hair color.

Since each hair reacts differently, experiment with these methods gradually and control how your hair reacts.

Can I treat my hair with Senna / Cassia rather than with vegetable dyes ?

Answer : You can treat your hair anytime with Senna / Cassia Khadi®, even if your hair has just been colored. If you only color your roots, it is even recommended to regularly take care of the lengths of your hair.

Can gray hair coverage be done in just one step ?

Answer : It depends mainly on the type of your hair but also on the shade chosen. The Light Brown and Natural Hazelnut shades cover gray hair in a single step.

By doing a test on a strand of hair, you will be able to know if your hair is taking color well. Otherwise, it will be better to proceed with staining in two stages.

How does vegetable coloring react with chemically colored hair ?

Answer : In principle, it is possible to color chemically colored hair with vegetable dyes. In this case, it will absolutely be necessary to do a coloring test on a strand of hair, because depending on the type of hair, undesirable color results can occur. This applies especially to lightened hair, colored blond, which takes on the color very intensely or which can take on an undesirable tint.

We strongly advise against bleaching vegetable-dyed hair, since the color you want can change very strongly. If you want clarification, in any case, contact a competent hairdresser who, through his practice, will certainly master vegetable colorings.
