Glycolic acid and salicylic acid are used for the analysis of the scalp
Husband's scalp. Their shape is like soil, nourishing the hair and affecting the color. In the way of maintaining the scalp, glycolic acid and salicylic acid are both commonly used agents, but the characteristics of the two are different, and the effectiveness is also different, which cannot be ignored.

Glycolic acid belongs to the α-hydroxy acid class. Its molecules are small and can quickly penetrate the stratum corneum of the scalp, such as spring rain moistening the soil, promoting keratinocyte renewal. If the scalp is blocked due to the accumulation of old keratin, it can make the hair follicles unobstructed and the hair nourished. And it has the ability to moisturize, can retain water in the scalp, make it moist, such as a spring moisturizing the dry and cracked soil, and the hair is soft and shiny because of it. However, it is slightly stronger. If the scalp is sensitive, it may sting or redness at the beginning of use, so those with sensitive scalp should use it with caution. Try it on a small scale first, and gradually increase the dosage and frequency.

Salicylic acid is beta-hydroxy acid. Its lipophilicity is good, like a duck to water in the oil, it can penetrate deep into the hair follicles, dissolve sebum, remove oil and dirt, and is especially good at treating the greasy scalp and dandruff. And it has anti-inflammatory effect and can relieve scalp inflammation. If the scalp is itchy and red and swollen due to inflammation, it can be solved with it. However, long-term or excessive use may cause dry scalp and unbalanced sebum secretion, so it is necessary to control the dosage and cycle according to the condition of the scalp.

If the scalp is greasy and inflammatory, such as wet and waterlogged fields and diseases, salicylic acid is excellent, can clear oil and resist inflammation, and make the scalp environment normal. If the scalp is thick and the hair is dull, it looks like soil compaction, plants are sluggish, glycolic acid can be activated, promoting keratin renewal and revitalizing the scalp.

In general, when choosing glycolic acid or salicylic acid to protect the scalp, it is necessary to carefully review the characteristics of the scalp, and do it carefully, in order to get good maintenance, healthy scalp and lush hair.
