Is silicone oil the killer? Silicone oil: I'm so aggrieved, but you really can't leave me!


Original: understand hair sister


Friends who often pay attention to the Internet may have heard about a "Silicon resistant shampoo" activity before. The main idea is that after using the shampoo containing silicone oil, although it looks smooth, it seals the pores. After using more hair, it starts to lose hair and the hair quality becomes poor, which is unknown to consumers. Before long, some authoritative popular science websites began to refute the rumors, saying that the silicon content of shampoo is a normal phenomenon, which does not harm hair at all.


1 / everyone seems to have a point. Who should I listen to?


It's said that "Silicon" is not good. Why should shampoo add "Silicon"?


It's true that 90% of shampoos do contain silicone oil. Silicone oil is a chemical called PDMS, which can attach to the hair, fill the damaged area of hair scales, and make the hair surface smoother, which is often referred to in the advertisement as "repair" function. It can be said that when you use a shampoo and feel very soft and smooth, it's basically silicone oil.


If you are a shampoo manufacturer, you will definitely add "silicone oil" to the mainstream products, because there is no other reason, easy to use is the king. A product is aimed at the mainstream mass users, not the minority. Moreover, there is no real research report that PDMS is harmful to human body, and it is also indispensable in skin care products and cosmetics. Canceling the use of "silicone oil" is almost the same as going back to the last century in the technology of washing and care products - no one is so stupid! Of course, it can't be said that shampoo without silicone oil is not good, but it's different to adapt to people.


2 / is "silicone oil" in shampoo potentially harmful?


I can't say anything absolutely. Netizen "boycott silicone oil" is not objective enough, but popular science website thinks silicone oil shampoo is better and ignores some cases. Hair sister can tell you for sure that some people are not suitable for using silicone shampoo.


Someone on the wechat of fajie often consults with me about shampoo. One of my hair friends told me that there is no reason for my hair's oil and itch. I asked him what kind of shampoo he used. He said that it was bought on the supermarket shelf, and almost never changed the brand. It's always that kind. I recommended him to try the shampoo without silicone oil (the specific name is omitted). One month later, he said excitedly, "it's too comfortable. I don't need the shampoo with silicone oil after I die!"


There are many other examples of this, so I'm sure that some people are not suitable for shampoo containing silicon. This kind of people have oily hair, thick hair and sensitive scalp. You can use such a "repair" shampoo to wrap a layer of "silicone oil" on the outside of the hair. The hair is overloaded, the oil secretion is blocked, and some of the scalp is sensitive and itchy. Do you think it's comfortable? Some women say that they can't wash their hair cleanly. After washing their heads, they are as sticky as wax. I told them to try changing the shampoo without silicone oil. Most of the problems have been solved.


In addition, silicon free shampoo generally has little or no fatliquoring agent, which greatly reduces the burden on sparse hair. In addition, for people with hair loss, the choice of shampoo must be mild and the weak acid one is the best. Some oil control shampoo and dandruff removal shampoo are not only rich in grease, but also strong in alkalinity. They are substances that may cause real hair damage.
