On the use of glycolic acid on the scalp
If you want to make good use of glycolic acid on the scalp, you must first understand its properties. Glycolic acid belongs to the fruit acid category, which has the function of gentle exfoliation, can exfoliate old keratin, smooth the breathing of hair follicles, and promote the speed of scalp metabolism.

The method of use should first observe the shape of the scalp. If the scalp is very sensitive, or there is damage or inflammation, it should not be used to prevent irritation and aggravate the injury. If the scalp is healthy, it is feasible to try it on a small scale.

First take a small amount of glycolic acid solution, dip it in a cotton swab, apply it behind the ear or on the hidden part of the scalp, and wait for a while to see if there is redness, itching, and tingling. If there is no discomfort, it can be gradually used on the scalp

When using, the glycolic acid product can be diluted. Common glycolic acid products have different concentrations. Those with high concentrations need to be diluted with an appropriate amount of distilled water or mild scalp care solution to reduce the concentration to suit the scalp. The degree of dilution varies according to individual scalp tolerance. Beginners should be thin and then gradually increase.

When applying to the scalp, the action should be slow and uniform. You can dip your fingertips in the diluent, starting from the forehead, slowly apply it to the back of the head, and gently rub it for a while to evenly cover the scalp, and do not scratch vigorously to avoid hurting the scalp. The retention time should also be paid attention to. Beginners should not be used for a long time. It is appropriate to take three to five minutes, and then it can be delayed to ten minutes as tolerance increases.

When the time is up, wash the scalp thoroughly with warm water to ensure that the glycolic acid is washed away without leaving any residue. After washing, you can continue to use a mild conditioner or scalp care product to keep the scalp's water and oil balanced and nourish and moisturize.

In addition, the frequency of using glycolic acid on the scalp is also exquisite. At the time of initial use, once a week is enough, and when the scalp gets used to it, it can be gradually increased to twice a week. However, it must not be too frequent, so as not to exfoliate excessively and cause damage to the scalp barrier.

In short, use glycolic acid on the scalp, be careful, follow the steps, and observe the changes of the scalp, so as to clean the scalp and promote the health of hair roots without risk of damage.
