Research on the safety of fruit acid on hair after hair dyeing
Nowadays, the trend of hair dyeing is popular, and everyone seeks beautiful and unique hair color. However, the care after hair dyeing is also the key, which is related to the durability of hair color and the quality of hair. Fruit acid, which is used in the field of skin care and hair care, has attracted more and more attention. Its safety on hair after hair dyeing is worthy of further investigation.

Among fruit acids, glycolic acid is common. In the field of hair care, glycolic acid has unique properties. Its molecules are tiny, have strong penetration, and can enter the deep layers of the hair. After hair dyeing, the microstructure of the stratum corneum of the hair may change. If glycolic acid is used properly, it can help repair the stratum corneum and make the hair supple and shiny.

However, the use of glycol acid in hair after dyeing also poses a latent risk. During the hair dyeing process, the chemicals in the hair dye react with hair keratin to make the hair color adhere. The acidic properties of glycol acid may affect the stability of hair dye pigments. If the concentration is too high and used frequently, it may cause hair fading to accelerate. Because glycol acid can interact with the pigment particles in the hair, it is more likely to be lost from the surface of the hair.

The hair has been dyed again, and it may have been damaged. Although glycol acid can promote the renewal of the stratum corneum, it may be overused, or the damage to the stratum corneum of the hair may be exacerbated, resulting in dry, fragile and easy-to-break hair. Therefore, the use of glycol acid-containing products on hair after dyeing

If you want to use glycolic acid-containing hair care products on your hair after dyeing, you should test it on a small area of hair first. Check if there are any abnormalities such as allergies and fading. And when choosing a product, you should choose the one with the right concentration of glycolic acid. The frequency of use also needs to be controlled, not excessive. In this way, you can keep the color of your hair long-lasting while pursuing hair health.

In short, the safety of glycolic acid on hair after dyeing is subject to many factors. Users need to use glycolic acid-containing products reasonably according to their own hair quality and hair dyeing conditions in order to have both hair care and color retention.
