Recently, a statement that "the shampoo contains silicon can cause hair loss, hair loss, and itchy scalp" has spread on the Internet. The reporter checked the information and found that the post appeared in 2011, and now such remarks appear again.

Does the shampoo contain a substance like silicone oil, and is it really as problematic as this statement? The reporter visited various major shopping malls and found that most of the ingredients in the market for hair conditioners and shampoos listed in the ingredients list contained "polydimethylsiloxane", which contains silicone oil.

Procter & Gamble customer service staff who own hair washing products such as HiFi, Rejoice, Icarus and other brands said in a press interview that silicone oil is safe in most shampoos, and most shampoos and cosmetics on the market contain silicon. And the amount is passed national standards.

Yu Xueling, secretary general of the Guangdong Daily Chemical Chamber of Commerce, confirmed to reporters that silicone oil is not banned in the current regulations on cosmetics in China. Dr. Zhang is the technical director of a large daily chemical company and a visiting professor at Sun Yat-sen University. He told reporters that "the main role of silicone oil is to comb it, which is allowed in national standards." And "silicone oil caused by shampoos" There is no basis for this statement, and none of the relevant national standards say what impact it has and what problems it has.

According to the professional scientific website Nutshell Network, since the 1970s, silicone oil has been resident in shampoos and hair care products. The main role of silicone oil is to fill the gaps after the hair scales are opened, and to add it to the care products. It can be used to smooth rough and reduce static electricity.
