On whether it is feasible to leave glycolic acid on the scalp
The husband's scalp is an important place for the human body, attached to the hair, and nourished by qi and blood. Glycolic acid, a chemical agent, is used on the skin, and has been heard of, but whether it can be left on the scalp, needs to be explored in detail.

Glycolic acid has the ability to exfoliate, and on the facial skin, it can promote metabolism and make the skin rejuvenated. However, the structure of the scalp is different from that of the facial skin. On the scalp, the hair is clumped, the hair follicles are densely covered, and the meridians and collaterals are connected below, and the internal organs are connected. If you rashly leave glycolic acid on the scalp, you may have many changes.

First, although the stratum corneum of the scalp also has metabolism, compared with the face, its thickness, toughness and physiological function are different. The exfoliation of glycolic acid may cause excessive exfoliation of the stratum corneum of the scalp, and the barrier is damaged. Once the barrier is broken, external evils, such as bacteria, viruses, etc., can easily take advantage of the void, causing scalp inflammation, such as itching, redness, desquamation, etc., or one after another.

Second, the hair follicle is the foundation of the hair, and the stimulation of glycolic acid may affect the microenvironment of the hair follicle. The growth cycle of the hair follicle is regulated by various factors inside and outside the receptor, and the intervention of glycolic acid may disrupt this regulatory mechanism, causing the hair follicle to malfunction. In light cases, the hair becomes thinner and softer, and the growth is slow; in severe cases, the hair follicles may shrink, the hair falls off, and the hair volume is sparse.

Third, under the scalp, the meridians are vertical and horizontal. Meridians, the channel where qi and blood run. If glycolic acid penetrates into the meridians through the scalp, or interferes with the circulation of qi and blood, and then affects the function of the viscera. Although this effect may not appear immediately, it should not be underestimated if it accumulates for a long time.

Therefore, if you want to leave glycolic acid on the scalp, you should be cautious. You must first carefully check the characteristics of your own scalp and whether it is tolerated; you need to consult professional people, such as doctors and dermatologists, to understand its advantages and disadvantages. Do not act rashly, so as not

To sum up, when glycolic acid is left on the scalp, it is appropriate to evaluate the situation and weigh the pros and cons to ensure the health of the scalp and the prosperity of the hair.
