"On whether common glycolic acid can be used on the scalp"

Husband's scalp is the root of hair and the special part of the skin. Today I have doubts, can common glycolic acid be applied on the scalp?

Glycolic acid is unique. It has a rejuvenating effect in skin care, can exfoliate and promote metabolism. However, the skin of the scalp is different from the skin of the face and body. The scalp is thin and sensitive, and it is where the roots of the hair are, which is related to the growth and decline of the hair.

If you rashly use ordinary glycolic acid on the scalp, first, the stratum corneum of the scalp is different from other places, or it is difficult to withstand the exfoliation force of glycolic acid, resulting in damage to the stratum corneum, weakened barrier function, and easy to cause itching, redness and swelling. Second, the micro-environment around the hair root is subtle, glycolic acid may interfere with its normal physiology, affect hair growth, or even cause loose hair roots and hair loss.

However, if the scalp problem does require glycolic acid intervention, be cautious. Be sure to carefully observe the condition of the scalp first, consider the skin quality and sensitivity. And it is necessary to start with a very low concentration, try it on a small scale, and observe its reaction. If there is no abnormality, then gradually control the dosage and frequency.

In short, common glycolic acid is used for the scalp and should not be taken lightly. When considering the pros and cons with scientific method and prudence, it is the way to protect the scalp and nourish the hair.
