As an amino acid shampoo, there are many kinds of amino acid surfactants to choose from. Sodium lauroyl sarcosinate is the most basic one. At present, some shampoos use sodium lauroyl sarcosinate as the main surfactant. There are also many other amino acid surfactants, such as sodium lauryl glutamate, potassium lauryl glutamate, sodium lauryl glycinate, potassium lauryl glycinate and other amino acid surfactants. Among them, shampoo with glutamate surfactant as the main body has low irritation and weakly acidic pH value, which is the pH closest to the scalp and is a very good choice.


The reason why silicone-free shampoo is difficult to completely replace silicone shampoo is that the hand feel after washing the hair is slightly worse, slightly dry, and the combing is difficult to reach the level of silicone-containing products, so it is necessary to match hair care and hair care products. General rinse-off conditioners are not fully competent for the requirements of smoothness and brightness of hair. In recent years, companies such as Procter & Gamble, Unilever, and L'Oreal have launched "hair essence" products, which have given consumers a sense of satisfaction. However, these "hair essences" are all made of silicone oil, with volatile cyclopentasiloxane as the main component, combined with high molecular weight polydimethylsiloxane (alcohol), etc., and silicone oil components cannot be avoided. Currently, there are few hair essence products on the market that do not contain silicone oil.
