On the feasibility of glycolic acid for the scalp
If you want to study whether glycolic acid can be used on the scalp or not, you need to consider many reasons in detail. Glycolic acid belongs to the class of fruit acids, which are often used for skin rejuvenation and skin improvement. It can exfoliate, make the skin smooth and delicate, and promote metabolism significantly.

However, the scalp skin is different from the facial skin. The scalp has many hairs and strong sebaceous glands secretion, and its physiological environment is unique. If you rashly use glycolic acid on the scalp, there may be several considerations. First, the stratum corneum of the scalp is thinner than the face and tolerates glycolic acid differently. If the concentration is too high, it is easy to cause scalp irritation, itching, redness and swelling, and even damage the hair follicles, hindering the healthy growth of hair. Second, glycolic acid may affect the balance of microbial communities in the scalp. The scalp is home to a variety of microorganisms, which are crucial to maintaining the ecological stability of the scalp. Glycolic acid intervenes, or disturbs this balance and causes scalp diseases.

If you want to use glycolic acid on the scalp, you should be cautious. Take a small area of scalp for trial first, and observe whether there is any discomfort. And the initial concentration should be low and adjusted gradually. At the same time, pay attention to the scalp reaction. If you see any adverse phenomena, stop using it immediately. Furthermore, keep the scalp clean so that glycolic acid can play a better role and reduce the risk of irritation.

In short, whether glycolic acid is used on the scalp, whether it is feasible or not, your mileage may vary. You must make a careful choice based on factors such as your scalp condition and tolerance
