Everything you need to know about scalp exfoliation.

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.

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.
