On the method of using glycolic acid for greasy hair
Nowadays, there is a problem of greasy hair, and everyone is seeking a good remedy to solve it. Glycolic acid is very effective in regulating greasy hair.

The reason why glycolic acid can be used for greasy hair is because of its unique properties. It is moderately acidic and can adjust the acid-base balance of the scalp. If the acid-base of the scalp is out of balance, the oil secretion is often excessive, resulting in greasy hair. Glycolic acid enters, so that the acid and base are calm and the oil secretion is gradually normal.

As for the usage, the first thing to choose is a suitable product. There are many shampoo products on the market, and there are also many people containing glycolic acid. It is necessary to carefully check its formula. The concentration of glycolic acid should be moderate. If it is too high, it may hurt the scalp. If it is too low, it will be difficult to show the effect. Usually, the concentration is between 2% and 5%, which is more suitable.

When using, first moisturize the hair with warm water to make the hair fully moist. Take an appropriate amount of glycolic acid shampoo in the palm of your hand, gently rub it until it is rich in foam, and then apply it evenly to the scalp and hair. Gently massage the scalp with the pulp of your fingers, rather than scratching with your fingernails, to avoid hurting the scalp. Massage for a while, about three to five minutes, so that the glycolic acid can fully act on the scalp and hair, adsorbing and decomposing excess oil. Then rinse thoroughly with water to ensure that no shampoo remains.

However, there are also points to pay attention to when using glycolic acid. At the beginning of use, some people may have a slight tingling sensation on the scalp, because the scalp is still uncomfortable with it. If the tingling sensation is strong and long-lasting, stop using it immediately to prevent damage to the scalp. Also, during use, the scalp may feel slightly dry, which is a normal phenomenon, and a conditioner can be used appropriately to nourish the hair. However, the conditioner should not be applied to the scalp, but only to the ends of the hair, so as not to increase the burden of scalp oil.

In short, glycolic acid is a good way to condition greasy hair, but it needs to be used with caution. Only by following the correct method can the hair be kept fresh and supple.
