The reason why silicone-free shampoo is difficult to completely replace silicone shampoo is that the hair feels slightly worse after washing, 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 smooth and shiny hair. In recent years, companies such as Procter & Gamble, Unilever, and L'Oreal have launched "hair essence" products, which have made consumers feel satisfied. However, these "hair essences" are all made of silicone oil, with volatile cyclopentasiloxane as the main ingredient, combined with high molecular weight polydimethylsiloxane (alcohol), etc., and silicone oil ingredients cannot be avoided. At present, there are few hair essence products that do not contain silicone oil on the market.
