When it comes to the application of common glycolic acid in the hair
For the husband's hair, it is very important to maintain the skin. The use of common glycolic acid in the hair also has its own way.

First know the properties of glycolic acid. It has the ability to gently exfoliate, clear the dirt and greasy hair, and promote smooth hair follicles. However, it is slightly acidic, so be careful when using it.

Before using, clean the hair. Wet your hair with warm water to moisturize the strands of your hair, then take an appropriate amount of hair products containing glycolic acid, such as shampoo or conditioner (if it is a unilateral glycolic acid solution, it needs to be diluted in proportion), and gently rub it on the ends of the hair, especially where the roots of the hair are connected to the scalp. The pulp of your fingers is slowly rubbed, imitating the state of rivers and rivers, so that the glycolic acid can be fully melted into the hair scale and oil, which lasts about three to five minutes.

Then, clean with warm water. The temperature of the water should not be too hot to cause damage to the hair, nor too cold to cause glycolic acid to remain. After cleansing the hair, you can observe the texture of the hair. If it feels dry, you can supplement it with a nourishing hair mask. Apply an appropriate amount of hair mask to the middle and tip of the hair. This section of the hair is easily damaged and needs more care. Wait for a few minutes, until the nutrients of the hair mask penetrate, and then rinse with water.

Use glycolic acid on the hair. It should not be frequent at the beginning, but once or twice a week. When the hair is gradually adapted, you can increase the frequency as appropriate. And during the use period, if there is any discomfort, such as itching or tingling, stop using it immediately and ask a doctor for medicine.

In this way, use ordinary glycolic acid in the hair in a prudent state to get a moist and healthy hair and show a different style.
