On whether it is feasible to use glycolic acid toner on the scalp
Recently, many people have explored the methods of skin care and hair care. During this period, whether glycolic acid toner can be applied to the scalp has attracted much debate.

Glycolic acid is a type of fruit acid, which is often seen in facial skin care products. It has the ability to exfoliate, promote skin metabolism, and improve skin quality. However, compared with the facial skin, the scalp skin is unique. On the scalp, there are many hairs and dense sebaceous glands, and the condition and sensitivity of the stratum corneum are different from that of the facial skin.

If you rashly use glycolic acid toner on the scalp, it may have multiple effects. First, the acidic properties of glycolic acid may cause an imbalance in the acid-base balance of the scalp. The scalp has its own stable acid-base environment to maintain the health of the hair follicles and the harmony of the microbial community. Once the balance is broken, microorganisms can breed disorderly, or cause discomfort such as scalp itching and redness. Second, the exfoliation effect of glycolic acid can rejuvenate the skin on the face, but not on the scalp. Excessive exfoliation of the scalp may cause damage to the scalp barrier, which greatly reduces its ability to resist external stimuli, which can lead to various scalp problems, such as dryness, desquamation, and even follicular inflammation.

However, there are also opinions that if the concentration of glycolic acid toner is appropriate and the individual scalp is well tolerated, it may be possible to try it. But this must be done with caution. Do a trial test on a small scalp area beforehand to observe whether there are any adverse reactions. If there is no difference in the scalp within a few hours to a day, the scope of use can be gradually expanded. And the frequency of use also needs to be strictly controlled, not too frequently.

To sum up, the use of glycolic acid toner on the scalp, although not absolutely, risks and opportunities coexist. Users must carefully observe their scalp condition, weigh the pros and cons, make prudent choices, and must not act blindly, so as not to damage the health of the scalp.
