Henna coloring is one of the most popular coloring capillary techniques. But is it possible to do a chemical coloring after henna?

Indeed, people who try this natural coloring for the first time often wonder whether it is possible to switch back to the chemical coloring .


What is coloring and what is henna dyeing?

Before I give you the answer to the question, it is important to know what henna is.

Did you know that there are two types of henna: neutral henna, which contains no colouring pigment; and natural henna, a shrub whose leaves contain a more or less intense amount of natural colouring pigment called lawsonia.

The natural henna powder, from color red, allows a coloring auburn or copper colour, with a very natural finish.

Just like coloring , which is 100% vegetable-based, it has numerous advantages for the health of the hair: shine, volume, protection thanks to a protective sheath surrounding the fiber hair, anti-dandruff, anti-hair loss, etc.

A vegetable dye is a mixture of several dyeing and ayurvedic plant powders (indigo, turmeric, chamomile, etc.).

It may or may not contain henna.


A coloring chemical after henna dyeing: the condition of this coloring

Yes, it is possible to switch back to coloring after a coloring henna.

However, it is imperative that the henna used is 100% pure and of natural origin.

The risk lies in the incompatibility of the products, in case the origin of the powder is doubtful.

Some henna may contain additives and metal salts such as sodium picramate.

The latter is a highly allergenic component that can cause violent chemical reactions.

These chemical agents certainly accentuate color, but they also damage, weaken and dry out the hair.

Moreover, they attack the scalp.


Discolouration after a coloring plant-based henna

If you want to change your color to blond, you should know that home bleaching is not recommended after coloring , as long as it contains indigo, which is the case for most colorings plant-based .
