Recently, a statement that “shampoo contains silicon can cause hair loss, hair loss, and itchy scalp” has been spread on the Internet. The reporter checked the information and found that this online post appeared in 2011, and now such remarks have appeared again.
Does shampoo contain silicone oil? Is it really a problem as claimed? The reporter visited major shopping malls and found that the ingredient lists of most brands of conditioners and shampoos on the market list contain “polydimethylsiloxane”, that is, silicone oil.
The customer service staff of Procter & Gamble, which owns hair care products of Head & Shoulders, Rejoice, Clairol and other brands, said in an interview with reporters that silicone oil in shampoo is safe. Most shampoos and cosmetics on the market contain silicon. And the dosage is in compliance with national standards.
Yu Xueling, secretary-general of the Guangdong Daily Chemicals Chamber of Commerce, confirmed to reporters that silicone oil is not banned in my country’s current cosmetics-related management regulations. Dr. Zhang is the technical director of a large daily chemical company and a visiting professor at Sun Yat-sen University. He told reporters, “The main function of silicone oil is combing, and its use is allowed in national standards.” And “silicone oil in shampoo causes hair loss.” There is no basis for the statement, and the relevant national standards do not mention its impact or problems.
According to Guoke, a professional science website, silicone oil has been used in shampoos and hair care products since the 1970s. The main function of silicone oil is to fill the gaps after the hair cuticles are opened, and is added to shampoos and care products. It can be used to smooth out roughness and reduce static electricity.
