Shampoo with silicone oil can hurt your scalp?

In the past two years, silicone-free shampoos have been the "net red" in the shampoo industry. Because it is said to be "refreshing, non-greasy, and protects the scalp from falling off," whether or not it contains silicone oil has almost become a benchmark for judging whether a shampoo is excellent. But in fact, can silicone-free shampoos be effective against allergies and hair loss?

Dr. Jing Jing introduced that silicone oil refers to simethicone, which is the common name of polydimethylsiloxane (PDMS). Polydimethylsiloxane (PDMS) as a hair conditioner, its role in shampoo is to fill the gaps between the outermost layers of hair, make the hair more supple, and reduce the occurrence of knots and other phenomena .

Current research suggests that the "silicone oil component" added to shampoos such as polydimethylsiloxane has a stable structure, is hardly absorbed by human skin and the gastrointestinal tract, and has basically no irritating effect on the skin. Under normal use, silicone oil shampoos are not harmful to the body. In addition, the current commercial shampoos do not contain more than 4% silicon. When shampooing, the role of the cleaning ingredients in the shampoo and running water rinses out the remaining content on the hair. Therefore, the silicone oil shampoo blocked by the Internet blocked the pores and caused hair loss. Most of them were manufacturers' gimmicks.
