On the effect of glycolic acid on hair
In recent times, the way of skin care has become increasingly popular, and many skin care ingredients have gradually become known to everyone. Glycolic acid is one of them. It is commonly found in various skin care products, but its impact on hair can also be investigated.

Glycolic acid, a type of fruit acid, has unique chemical properties. In skin care, it is often praised for its ability to promote keratin metabolism, improve skin texture and color. As for hair, its mechanism of action is also very interesting.

The health of hair is related to the state of hair follicles, hair structure and many other factors. Glycolic acid may have an impact on the scalp environment due to its mild acidic properties. A moderately acidic environment may be conducive to inhibiting the growth of certain harmful microorganisms, which is the basis for maintaining scalp health. If the microbial community of the scalp is unbalanced, it often causes various scalp problems, such as itching, dandruff, etc. Glycolic acid may be helpful in this.

In addition, glycolic acid may also have an effect on the hair itself. Hair is mainly composed of keratin, and long-term exposure to the external environment can easily cause keratin damage. Glycolic acid may help repair and strengthen the hair structure by interacting with keratin. Studies have shown that under the action of appropriate glycolic acid, the toughness and luster of the hair are improved, which may be due to the promotion of cross-linking between keratin molecules and the stability of the overall structure of the hair.

However, everything has a degree. Although glycolic acid has the above potential benefits, improper use also has drawbacks. If its concentration is too high or used too frequently, or it irritates the scalp and causes discomfort. The scalp skin is relatively sensitive. Excessive concentration of glycolic acid may destroy the function of the scalp barrier, causing water loss and exacerbating scalp dryness.

Therefore, if you want to use glycolic acid to care for your hair, you should be cautious. It is advisable to check the ingredients of the product carefully and choose the appropriate concentration. At the time of initial use, you can try it on a small scale to observe the reaction between the scalp and the hair. After there is no discomfort, you can use it normally. And the frequency of use should be determined according to the condition of the individual scalp and hair, and you must not follow the trend blindly. In this way, it is expected
