A piece of news spread widely on the Internet: surveys show that silicone oil, which is often said to be a smoothing agent, accounts for 90% of domestic shampoos. Although the hair is smooth after use, it will block the hair follicles, causing the hair to dry and cause hair loss .
As soon as the news spread, people talked about the discoloration of silicone oil and began to choose silicone-free shampoo. Seeing business opportunities, the merchants specially launched several shampoos with "silicone-free" as their selling point. However, these "silicone-free" products are generally much more expensive than products containing silicon compounds, and the hair is not smooth and difficult to comb after use, especially for women with long hair, which means that the head is big .
Is silicon-containing shampoo really so scary? Does the silicon-containing shampoo really block the pores and cause the problem of hair loss and hair loss?
As early as the 1950s, silicon has been used in the cosmetics industry. Nowadays, there are traces of silicone oil in various detergents. Silicone oil has a certain viscosity, ductility, and moisturizing effect. In shampoo, the main effect is lubrication, that is, to reduce friction resistance. In the whole system, silicone oil is relatively stable and will not affect the decontamination ability of shampoo .
Hair is born from the hair follicles in the scalp, and the main component is keratin. Under the microscope, you can see the uneven hairy skin on it. This kind of thing that looks like a fish scale is the hairy scale. When there are damaged hair scales on the hair, the friction between the hair increases, and the hair begins to be tangled together, making it difficult to comb. The reason why silicone oil makes the hair soft is because after shampooing with silicone oil, the hair scales Will open, silicone oil is attached to the cuticles to fill in the gaps between the cuticles, and it will naturally be smooth.
Internet rumors say that using silicone oil shampoo will block the pores. Is this really the case? Silicone oil is a kind of macromolecular substance, which cannot be absorbed by hair follicles. Sometimes there are other ingredients in silicone oil, and its water solubility is also increased. It is even more unlikely that the hair follicles will be blocked. Moreover, there is not much silicone oil in shampoo (generally In other words, the silicone oil content in shampoo is 1%-2%), a lot of water rinse, coupled with the role of cleaning surfactant, there is almost no residue .
As for the theory of causing hair loss, it is unfounded. Under normal circumstances, the number of hair loss after each shampoo is between 50-100, which is a normal metabolism, so don't worry too much. There are many reasons for hair loss, such as seborrheic alopecia caused by endocrine causes, hair loss caused by mental stress, and even postpartum hair loss. But so far, there has been no authoritative statement confirming that silicone oil can cause hair loss, and all products that leave the factory have undergone strict quality inspections, and the content of ingredients meets the various indicators prescribed by the state, and safety assessments have been made, so consumers can rest assured to use .
