On the method of applying glycolic acid to the scalp
If you want to improve the quality of the scalp, or remove dandruff, or promote new skin, the method of applying glycolic acid is becoming more and more popular. The method is not light, so you should do it carefully.

At the beginning, you must clean the scalp, remove its scale and greasy, and make the pores open, so as to facilitate the entry of glycolic acid. You can use a mild shampoo first, gently rub it on the pulp of your fingers, rinse it with water, and wipe it dry.

Take an appropriate amount of glycolic acid solution every time, and its concentration should be used to measure the tolerance of the scalp. For beginners, choose a low-concentration liquid, such as 2% - 5%, to prevent excessive reactions. Dip a dropper or a cotton ball in the liquid and gently apply to the scalp, especially to the affected area, to ensure that it is even. When applying, it may feel slightly prickly. This is common. If the tingling is unbearable, it must be stopped immediately.

Apply and wait for a while. At first, it should not be left for a long time, about 3-5 minutes. Later, with increasing tolerance, it can be extended to 10-15 minutes. Do not scratch during this period to avoid damage to the scalp.

When the time is up, buffer with warm water, be sure to remove the glycolic acid, and then protect it with conditioner to moisturize the scalp hair and slow its irritation.

Glycolic acid should be applied to the scalp gradually. It can be applied every three or five days at first, and then gradually. However, it should not be too complicated to avoid scalp injury. And during the application period, avoid the hot sun to prevent scalp sensitivity and injury. If the scalp is red, swollen, rash or uncomfortable after application, seek medical attention immediately, and do not rely on yourself. In this way, the benefits of glycolic acid to protect the scalp can be obtained without the risk of damage.
