Shampoo is essential for washing the scalp and hair, but choosing it well is also an art.

So how to choose well? Because there are endless shampoos for all hair types.

Mild shampoo, for dry hair, for greasy roots, with or without silicone…

Is it difficult to know which product to choose to wash your hair?


Shampoos are cleansing products that contain surfactants to remove dust, pollution, dead cells, sebum or cosmetic residues, usually offered in liquid, cream, solid or powder form, often with a rinse.

Its main purpose is to save the hair from daily impurities and the accumulation of products brought during the week.

In short, shampoo is the first beauty treatment for your hair!

However, their formulations may differ according to the structure of the hair, the condition of the scalp or the treatments applied.


The skin is a very important organ that is responsible for ensuring the passage of sweat while preventing foreign bodies from entering the body. These foreign bodies include dust, microbes, and toxic molecules.

Since 80% of the body is made up of water, the skin needs to protect itself against drying out. Therefore, cress is accompanied by the secretion of an oily substance: sebum. Therefore, it ensures that the skin maintains its moisture level and thus remains soft, supple and intact.

Unfortunately, like any oily substance, sebum tends to absorb foreign bodies upon contact with the skin. If not drained, it creates a thick, blackish layer of sebum mixed with dust, bacteria and more or less toxic substances on the skin surface: this is what we call dirt.

At the head level, sebum also protects the hair by covering the scales and especially the space between the scales with a protective film.

There is a hydrolipidic film (a mixture of sweat, sebum, substance residues arising from the keratinization process of keratinocytes and water from the deep layers) on the scalp, which forms the living part of the hair and is implanted in its superficial layer. skin),

It is very important that the scalp, where the hair follicle is planted, is healthy and provides the necessary nutrients for hair growth.

Washing your hair with the appropriate shampoo is the guarantee of a healthy and balanced scalp, a healthy scalp that can give birth to beautiful hair full of vitality.

It is also a scalp that can function as a physical barrier of protection against bacteria and thermal insulation.

There are two areas of sebum in hair:
- mechanical protection against dust;
- chemical protection against oxygen and dehydration (dry hair) that will degrade the scales in the air.

As the days pass, sebum will accumulate in the hair, especially near the scalp. The movements of the hair also contribute to the spread of this sebum. As the amount of sebum increases, the film thickens. Hair becomes "oily" and tends to stick together, becomes heavy and gives an unsightly "wet" effect.

And of course depending on profiles, sebum production is more or less from person to person.


This diagnosis begins with a resistance test, which will give you an indication of the elasticity of the hair fiber. To do this, just pull a hair and see if it breaks. If so, your hair is sensitive and fragile.

The second step is to slide the fiber under your fingers to assess its roughness. The drier it is to the touch, the more care your hair needs and the less it opens.

The third stage takes place on your scalp, which is an important moment for choosing your shampoo.

The priority before choosing your shampoo is to assess your needs and analyze the condition of your scalp and hair.

Ask yourself the right questions:

- Do I see dandruff on my scalp?

-Does my scalp itch?

-Do I have redness or acne on my scalp?

-Is my scalp oily or just night sweats?

Lots of questions to get you closer to the best skincare routine you need.

Of course, you will need to integrate into your diagnosis the concept of your week-long washing frequency and the aggressions you experience daily in your daily life.

However, the best person who can definitively apply this diagnosis on the condition of your hair is your hairdresser.
