Silicone oil is one of the hair care ingredients. During the shampooing process, the emulsified silicone oil suspended in the shampoo will come into contact with the surface of the hair and will be adsorbed on the surface of the hair to form a protective layer, making the hair smooth, soft and easy to comb. The most commonly used shampooing agents are dimethicone and siloxysilicate. Dimethicone has the function of protecting the hair and reducing friction, and siloxysilicate can make the hair fuller. However, since silicone oil is not soluble in water, excessive use of shampoo containing silicone oil will cause it to deposit on the surface of the hair and in the hair follicles, affecting the normal metabolism of the hair and making the hair look flat. In this way, the advantages and disadvantages of the two are obvious. There are some silicone-free shampoos on the market that use the same or similar surfactants as silicone shampoos. In this case, this silicone-free shampoo lacks the protection of silicone oil and may be more irritating to the scalp.
