On the brightening effect of glycolic acid on hair
The brightening effect of glycolic acid on hair must be investigated and its use must be investigated. Glycolic acid, in the field of skin care, is often known for exfoliating and promoting metabolism. However, its effect on hair can also be investigated.

To observe the properties of glycolic acid, it is weakly acidic and can interact with the keratin of hair. The color of hair originates from melanin produced by hair follicle melanocytes. The amount and distribution of melanin determine the color of hair. Glycolic acid may affect the structure or distribution of melanin through its acidity, and then may change the color of hair.

In practice, glycolic acid preparations are applied to the hair. At first, the color of the hair may change slightly, but this change is not achieved overnight, nor can it be called good. The quality of the hair cover is different, and the environment of the scalp is also different. If the hair is weak and the scalp is sensitive, the use of glycolic acid may cause damage to the hair, such as dryness, fragility, or even breakage.

If you want to brighten the hair with glycolic acid, consider the situation when considering the situation. Try it on a small part of the hair first to see if it is uncomfortable. And the concentration and frequency of use must be careful. If the concentration is too high and the application is too frequent, it will not only fail to beautify the hair, but also harm it.

In short, glycolic acid can brighten hair, although it is possible, there are advantages and disadvantages. Users should carefully observe their own hair quality and exercise caution in order to obtain the effect of brightening without the risk of hair damage.
