The slogan "No silicone oil, no stimulation" is no stranger to consumers. In recent years, the "silicone oil" in shampoo seems to be the target of public criticism. It seems that only shampoo without silicone oil is a good shampoo. However, is it not good to have silicone oil in shampoo?
What on earth is silicone oil?
We have always said that shampoo contains "silicone oil", referring to "dimethyl silicone oil", the scientific name of polydimethylsiloxane (PDMS), shampoo products added with this substance, can play a role in smoothing hair.
How does silicone oil work smoothly?
Frequently scaled hair is severely damaged. During shampooing, viscous and ductile silicone oil can fill the voids of scales, reduce friction, smooth the surface of hair, and make hair soft and non-static.
The disadvantage of silicone oil, which is widely spread, is that it is inert and impermeable, blocking pores and causing hair loss.
According to Shi Fuxia, a maternal and child health physician in the Department of public health, hair loss caused by silicone oil is a rumor. Silicone oil is a macromolecule substance that will not be absorbed by hair follicles. Under the action of anionic surfactant and the washing of a large amount of water, silicone oil can be cleaned out. In fact, shampoo does not contain much silicone oil, only 1%~2%. The products with the most silicone oil are actually hair conditioner and hair film.
