The scalp is simply an extension of our epidermis and can be subjected to various stresses that disrupt its cellular renewal rhythm. This can lead to itching, irritation, and even dandruff. Exfoliation is not a practice solely reserved for the skin of the body and face, and proves to be of invaluable assistance in cleansing the scalp and consequently strengthening the hair.

Everything you need to know about the scalp.
The scalp is composed of the same layers as the skin: epidermis, dermis and hypodermis. Its thickness is around 6 mm. Its distinction from the skin of the rest of the body lies in its significant number of hair follicles (200 to 300 per cm2 on average). Consequently, it contains a lot more sebaceous glands and thus produces more sebum. The scalp also houses sweat glands responsible for the secretion of sweat. Moreover, this part of the body is richly vascularised due to the high density of hair follicles. The numerous nerve endings present are the source of a high sensitivity to touch and the environment.
Why should we exfoliate our scalp?
Pollution, stress, smoking, overexposure to the sun... These are all factors that disrupt the process of cellular regeneration and lead to the accumulation of dead cells on the surface of the scalp. This then results in the obstruction of hair follicles, affecting the overall health of the scalp (flakes, itching, excess sebum) and the hair (lack of volume, slowed growth, lack of shine).
In light of this, scalp exfoliation is recommended for all types of scalps. This practice not only partially removes dry and oily dandruff, but also stimulates micro-circulation and reoxygenates this area often suffocated under the hair.
Scalp exfoliation is recommended at the same frequency as that of the face and body, that is to say once or twice a week, no more.
Note : This practice remainsnot recommended for irritated or damaged scalps in order not tofurthersensitise them.
The Typology Scalp Exfoliant.
Our scalp exfoliant is a pre-shampoo gel that gently removes dead cells for a healthy and balanced scalp. It is applied to dry scalp, at the roots. The next step is to massage the scalp, leave the product on for 5 to 10 minutes and then rinse. The hair can then be washed with a regular shampoo , preferably sulphate-free.
This treatment provides a dual chemical and mechanical exfoliation due to the presence of three compounds:
The gluconolactone, a component of the P.H.A. family (poly-hydroxy acids), is a gentle chemical exfoliant that dissolves dead cells while stimulating scalp hydration.
The jojoba beads (INCI: "Jojoba Esters") are spherical mechanical exfoliants that stimulate microcirculation of the blood.
The silica powder (INCI: "Hydrated Silica") where it is about 100% natural mineral exfoliating particles that are smaller in size than jojoba beads, offering micro-exfoliation while respecting the scalp.
Furthermore, it is also enriched with aloe vera pulp (INCI: "Aloe Barbadensis Leaf Juice") to hydrate and soothe any potential itching, as well as with peppermint essential oil (INCI: "Mentha Piperita (Peppermint) Oil") known for its stimulating properties on hair growth and with eucalyptus globulus essential oil (INCI: "Eucalyptus Globulus Leaf Oil") appreciated for its soothing virtues.
