Ordinary glycolic acid can be used on the scalp to cover the skin of the scalp, which is particularly delicate compared to other parts. Although glycolic acid has the effect of rejuvenating the skin, it has a certain degree of acidity.

If applied to the scalp rashly, it may cause scalp discomfort. In light cases, it may feel itchy and tingling; in severe cases, it may cause scalp allergy, redness, swelling, desquamation and other diseases.

Therefore, if you want to use glycolic acid on the scalp, you should be cautious. It is necessary to carefully review the characteristics of the scalp, or consult a professional, such as a dermatologist, hair specialist, etc. Get their professional guidance before it can be done, so as not to damage the health of the scalp.
