On the application of glycolic acid to hair
The use of glycolic acid in daily chemicals has become more and more popular in recent years, and many people ask whether it can be used in hair.

View the properties of glycolic acid, which is one of the fruit acids, with weak acidity, often used in facial skin care to exfoliate, promote metabolism, and rejuvenate the skin. The structure of hair is different from that of skin. Hair is composed of keratin and covered with hair scales. The state of hair scales is related to the luster and smoothness of hair.

If glycolic acid is applied to hair, its acidic or hair-causing scales are damaged and opened. At first, the hair may feel slightly supple, because the acidity makes the hair scales temporarily fit. However, if used for a long time, the hair scales are overopened, keratin is easily lost, and the hair gradually loses moisture and nutrients, resulting in dryness, fragility, and breakage. And the scalp skin is delicate, and glycolic acid or irritation can cause scalp discomfort, itching, and even inflammation.

Therefore, ordinary glycolic acid should not be used lightly for hair. If you want to care for the hair, choose a product specially developed for the hair, which is in line with the characteristics of the hair, and is the right way to nourish the hair, which can keep the hair healthy and shiny.
