When it comes to hair colouring, plant based hair colouring is on the rise, and for good reason: generally made up of a mixture of water and crushed roots or leaves, it is the healthy hair dye par excellence, respectful of the hair and non-harmful.

allergy to plant-based colouring: is it possible


It has become a solid alternative to the traditional colorings , which is much more aggressive to the scalp due to the heavy chemical compounds it contains.

In addition, Mother Nature and her armada of various plants naturally offer a beautiful range of colours.

But is the picture perfect?

Not necessarily!

A plant-based is also a living organism, full of active substances, and therefore likely to cause another organism to react, particularly through allergy.

Some examples of the minor setbacks that can occur when opting for a coloring plant.

Queen of blondness: chamomile

Chamomile is unrivalled for enhancing luminous highlights .

Is it safe?

In principle, yes.

As a calming plant, it generally triggers few allergic reactions.

However, beware of pollen allergies.

That being said, since chamomile clearing is done by applying a hot decoction, there is little risk of this happening.

For brown hair: walnut stain

There's nothing like walnut stain, which is the extract from the bark of the walnut tree, to give a beautiful depth to brown hair.

Distrust of rigour: if you are allergic to nuts, in its food use, it is better to avoid using this plant-based dye.

The symptoms after application could be the same as in the case of a food allergy: hot flushes, redness, skin rashes, etc.

The essential henna

The powdered henna leaf is the undisputed star of colorings .

Used for thousands of years as a cosmetic product, its most emblematic hue is orange.

Is it harmless?

In principle, yes.

On the one hand, it must be used "pure" and without any chemical additives, and on the other hand, its use must be reserved for adults: in fact, this plant has compounds which, although they are harmless for an adult, can be toxic for children.

At Biocoiff', the henna is pure, certified ORGANIC, and free of any metallic salts.

Dyer's madder

Aptly named, this plant-based provides, through its rhizomes, the best natural red dye that can exist, provided it is combined with a henna base.

Is there a possible complication?

In theory, no, especially since the garantee is also a medicinal plant!

However, since it should be added to henna for the sake of effectiveness, vigilance is required with regard to young children.

Indigo: the friend of blues

This shrub provides leaves which, after grinding, produce wonderful blues.

Like henna, this plant-based dye should not be a problem, as long as it is used absolutely pure.

As living elements and full of active ingredients, dye plants can always cause an allergic reaction.

However, they are much more recommendable than traditional dyes and there is no reason to be overly suspicious of them.

The risks of allergy are very low, and the cases of allergies that we have recorded since 2005 in our hair salons do not exceed ten!

So, without any problem, you can trust in plants and their colouring, vitalising and sheathing powers.
