On the nourishment of the hair of the husband's skin when glycolic acid is left on the scalp
It is related to external use. Glycolic acid is gradually gaining favor in the field of skin care and hair care. However, when applied to the scalp, it is very elegant to leave it for a long time.

Glycolic acid has the ability to exfoliate and promote metabolism. However, the scalp skin is more delicate and sensitive than other parts. If left for too long, it may cause irritation, redness, swelling, itching, damage the health of the scalp, and even the hair is also affected by it, resulting in loss and sparsity.

When glycolic acid is first used on the scalp, it should be used for a short time. You can take a small amount first, apply it thinly to the local scalp, and leave it for about two to three minutes. During this period, observe the scalp reaction carefully. If there is no abnormality, it can be used gradually for a later period of time. However, even if the tolerance is good, it is usually not suitable for a single indwelling for more than fifteen minutes.

And different individuals have different tolerances to glycolic acid. Age, skin type, past medical history of the scalp, etc., are all influencing factors. Younger people have strong scalp vitality, or slightly tolerate it; older people have gradually deteriorating skin and poor tolerance. Oily scalp, or drier scalp, can slightly tolerate it. Those who have suffered from scalp inflammation need to be cautious when using it, and it is recommended to consult all doctors first and follow their instructions.

Furthermore, the frequency of use is also related to the duration of indwelling. If it is used frequently, the lien time should be short each time; if the interval is long, the lien period can be extended slightly, but it is still important not to overdo it.

If you want to nourish the scalp with glycolic acid, when you observe the state of the scalp, according to individual differences, determine the length of the lien, and must not be generalized. Only by prolonging it can you achieve the purpose of maintenance without damaging the health of the scalp hair.
