The importance of scalp care:
Scalp is the source of hair, which is more delicate and fragile than other parts of the human body. Scalp is a part of the skin, the soft tissue covering the skull, and the first barrier to isolate external invasion. It has the same tissue structure as the skin in other parts of the human body.
There are also some differences between scalp and other parts of the body. The metabolic cycle of skin cells is 28 days, while that of scalp cells is only 14-2 1 day. Therefore, the scalp is more delicate and fragile than facial skin, and it is also more vulnerable to external invasion.
At the same time, the oil gland secretion cycle of scalp is faster and more vigorous than that of facial skin, which provides favorable conditions for the survival and reproduction of bacteria. Therefore, only the necessary maintenance of the scalp can keep the scalp healthy.
