On the feasibility of leaving glycolic acid in the hair to sleep
Or ask: "Glycolic acid in the hair, can you sleep peacefully?" This matter is related to the health of the scalp and the texture of the hair, and cannot be studied carefully.

Glycolic acid has the ability to exfoliate and is often used in facial skin care. If applied to the hair, it may remove the old and waste exfoliation of the scalp, smooth the breathing of the hair follicles, stabilize the hair roots, and revitalize the hair. However, its nature is sharp. If the concentration is improper and the usage is inappropriate, it may hurt the scalp, cause itching, tingling, or even make the hair brittle and easy to fold.

If you want to leave glycolic acid in the hair to sleep, you should first consider your own scalp skin. Sensitive people should be cautious, or try it on a small area of the skin first to see if there is any discomfort. And the concentration of glycolic acid must follow the product instructions, and do not increase it. When using, it is advisable to gently rub the scalp with the pulp of your fingers, apply it evenly and thinly, and do not accumulate in one place. After use, it must be cleaned with water, so as not to leave any residue.

It should be noted that even if the scalp tolerates it, glycolic acid will remain in the hair for a long time, or it may cause microecological imbalance of the scalp. Therefore, it is not a long-term solution, and it is appropriate to use it occasionally to detect changes in the scalp and hair, and change it in a timely manner.

In short, leaving glycolic acid in the hair to sleep is feasible for those who tolerate it. However, they must follow the scientific method and be cautious in order to receive the effect of hair care and avoid the risk of hair injury.
