The basic function of shampoo is to clean, and there is nothing to do with pathological dandruff, hair loss and other issues. Many "functions" are just the gimmicks of business sales. The shampoo currently bought, if the pursuit of hair is supple, it is easy to make the hair greasy, dirty and collapsed. If you want to purify your hair, it is easy to make your hair rough, dry, scattered, and poorly repaired. The two themselves are contradictory and difficult to do at the same time.
When consumers choose shampoo, they must first understand their hair quality characteristics, whether it is oily, neutral or dry hair, and then choose the right shampoo; secondly, choose the brand that suits you, the shampoo formula of different brands. There are differences. At present, many shampoos do not indicate specific ingredients, and individual labeled ingredients may not exist.
Some shampoos claim to contain Chinese medicinal ingredients such as saponins, Shouwu, Chinese angelica, and ginseng. Experts say that medicine proves that they have nourishing effect on the scalp and hair. It can nourish the scalp and hair by external washing. It is confirmed that many businesses exaggerate the efficacy of such shampoos.
There is also a class of amino acid shampoo, which is a shampoo with an amino acid surfactant as the main surfactant (only two drops of the amino acid shampoo in the strict sense), amino acid surfactants and other surfaces. The active agents have a good synergistic effect. The use of amino acid shampoo can play a certain role in the repair of hair. And the amino acid shampoo is mostly weakly acidic, the pH value is between 5.5 and 5.8, and the pH value of healthy scalp is weakly acidic. Using weak acid shampoo will not damage the balance of healthy scalp PH and make the scalp healthy.
