What you should know about natural plant hair colors

Dunkle Haare mit Rotfärbung

Natural plant hair colors provide the hair with important ingredients and protect it sustainably against external influences. This helps your hair stay healthy, voluminous and shiny. Conventional chemical colors break up the hair structure forcibly so that the color can penetrate the hair. Vegetable hair colors, on the other hand, lie gently on the cuticle layer of the hair, and are therefore deposited on the outside of the hair. Natural hair colors protect your hair and promote healthy hair growth.

Please always make sure that the chosen plant color really is chemical-free. Some producers add some of the chemicals to the plant colors, which are also found in synthetic hair colors. These are natural colorations. However, they are similarly harmful as conventional chemical products.

How do synthetic hair colors damage your hair?

Chemical hair colors contain substances that are hazardous to health, such as ammonia, resorcinol and phenylenediamine. Over time, conventional dyes lead to damaged hair and irritated scalp.

Ammonia irreparably breaks up the horny scales of the hair so that other substances can penetrate the hair. Synthetic hair colors belong to these substances.

Phenylenediamine belongs to the so-called aromatic amines. These ensure a permanent hair coloration. They are problematic because amines can cause severe irritation and allergic reactions. Amines can also have carcinogenic, mutagenic and reproductive toxic risks.

Resorcinol has a bactericidal effect, is flammable and is classified as a hazardous chemical. It is often contained in oxidative hair dyes, i.e. conventional colorants. It is used to nuance the color shades.

Thus, when synthetic hair dyes are used frequently, the hair can dry out and become brittle over time. Synthetic hair colors are problematic for health, because they damage the hair structure and are said to lead to an increased risk of cancer.

What are vegetable hair colors made of?

Natural hair colors are colorants from purely natural, vegetable sources. Usually, suitable plant leaves are processed into powder. Henna, indigo and cassia are particularly popular. Spices can actually also be used for coloring. You probably already have everything you need at home. If you have chamomile, black tea or coffee on your regular shopping list, you can already start dying.

How do plant hair colors work?

Hair colors extracted from plant parts, such as barks, leaves or shells lie around your hair like a glaze. This protects the hair and guarantees a natural shine. As we already know it from artificial hair colors, the color intensifies if you let it set in your hair longer.

At first use, the greenish powder of many vegetable hair colors may confuse you. But don’t worry, the hair will not be dyed green. The green color is due to the chlorophyll of the plant, which does not give the hair any color. However, suitable plants contain other coloring substances.

But only on contact with hot water, the colorants “lawson” and “indigo” are released. These give your hair the desired color. Depending on the water temperature and the mixing ratio of the plant substances, a wide variety of hair colors can be achieved.

The coloring effect is often achieved in combination with natural acids, such as fruit vinegar or lemon. There are also alkaline plant colors. These allow the cuticle layer of the hair to swell and ensure that the colorants are stored in the hair.

Despite many good attributes of vegetable hair colors, they can only be used for desired darker hair tones. Lightening your hair color with plant color is unfortunately not possible. To lighten your hair color you need aggressive hydrogen peroxide, which completely decolorizes the hair before coloring it again with the desired lighter color.

How do I find the right plant hair color?

First check the color results on the product packaging. If you have doubts and can’t decide between different color tones, you should choose the lighter tone. Going a shade darker is always possible afterwards – but if the result is too dark at first, you cannot lighten it with plant color.

In this case you have to wait until the color washes out a bit or lighten it chemically.

Can I color gray and dyed hair with natural plant color?

The greys can be easily concealed with plant hair colors. You may need to repeat the coloring process until all hairs are colored and the color tone is correct. If your hair is already heavily chemically dyed, we advise you to visit a natural hairdresser. This is not absolutely necessary, but the professionals will ensure an even color tone is achieved. This is a good idea because the hair structure has already been heavily strained before.

How do I use natural plant colors?

  1. Wash hair with neutral, silicone-free shampoo. For henna-based reds, cover the hairline and ears with a greasy cream. This prevents skin discoloration.
  2. Put the plant powder in a bowl and start to boil water. Protect your clothes from coloring, since you might get color stains.
  3. Mix the plant powder with hot water. This will activate the coloring molecules. Pay attention to the suggested temperature. This is crucial for the color result.
  4. Apply the mixture with the fingers or a brush. Then cover the hair with a cap. If you are unsure about the color tone, test the color for a strand of hair until you get your desired tone.
  5. Let the color set 30 to 60 minutes depending on the product; often it is recommended to wait a little longer.
  6. Rinse thoroughly with lukewarm water. Do not use shampoo for this. Wait at least 24 hours and then wash your hair as usual with your shampoo. This way the color will last longer.

How long does my natural plant coloring last?

How often you should recolor depends on the desired result. However, once your color tone is right, you only need to recolor every 4-6 weeks to cover the hairline and maintain the color. Due to environmental influences like UV rays and frequent hair washing, it may be necessary to recolor more often at the beginning.


Why should you ruin your hair with chemicals? Over time, conventional hair care products do us no favors. Ultimately, we all want to see our hair strong and shiny. Unfortunately, the artificial colorants put a stop to this if used too often. We therefore recommend that you try natural plant hair dyes for your next hair coloring.
