In the past two years, the shampoo market has witnessed a wave of silicone-free oil, and sales are very hot. Many brands are involved in this product segment and have launched their own silicone-free products. The overwhelming advertising campaign seems to have led many people to believe that silicone oil is the main culprit in scalp and hair health. In the shampoo products, there have been decades of silicone oil being suddenly pushed to the cusp. However, is this really the case? Silicone oil is really a "big villain", or is it innocent to be regarded as "back pot man"? Market research for silicone-free oil products claims to be healthier and the momentum of development is fast. Before the concept of “silicone-free, healthier” was widely publicized, people did not seem to have paid special attention to “silicone oil” in shampoo, but since silicone-free shampoo The alleged natural label has been launched in shampoo products, and the concept of no silicone oil has been quickly accepted by consumers, and has become a new focus for brands. The Beijing Morning Post reporter conducted a survey on the current shampoo market. Although the current shampoo market is still dominated by silicone-containing products, the silicone-free shampoo is rapidly expanding its market share, in addition to the leading sources of resources such as L'Oreal and Schwarzkopf. Silk, silk, and domestic brands such as bee, Icahn and other brands have no silicone oil products online. Earlier media reports showed that in 2015, only one source of non-silicone oil products occupied a market share of 4.6% in the Chinese shampoo market, achieving 360% annual sales growth. In the 2016 June 18th E-Commerce Year, Ziyuan's sales exceeded 52.09 million, and the sales growth rate reached 800%. Behind the hot silicone oil shampoo is the reality that silicone oil is questioned. Some silicone-free products in the propaganda indicate that silicone oil is insoluble in water, difficult to clean, and easily left on the scalp, causing problems such as scalp allergy, hair follicle blockage, hair loss, and dandruff. There are also some silicone-free products that suggest these problems in silicone-containing products by promoting their own advantages. Whether the company's voice contains silicon only depends on the different effects. It should be seen from the individual needs. The reporter found that although the current sales of silicone-free products are very hot, overall, the market share of silicone-containing products is large, and such as L'Oreal and Schwarzkopf. And Shiseido and other big care brands, although their products are involved in the silicone-free shampoo, but the proportion is relatively small, and such companies have not made a fuss about the concept of silicone-free oil, and does not deny the safety of silicone oil. Sex. For example, L'Oreal, a certain silicone-free oil product, on its packaging, the word “silicone-free oil” is very small and unobtrusive. It may not be found without attention. Another example is Shiseido, which also includes two production lines containing silicone oil products and silicone-free oil products. When it comes to how to treat silicone oil and how to balance the relationship between silicon and silicon-free products, the person in charge of Shiseido said that silicone oil is a kind of A safe and secure ingredient that can be used in everyday products. Silicone oil itself does not have a bad effect on the scalp and hair, and is still one of the most stable and effective supple ingredients. The reason why Shiseido Group has also produced silicone-free oil-washing hair care products is to meet the needs of different consumers. Silicone-free oil products are mainly aimed at consumers with scalp troubles and focus on creating a healthy scalp environment. At the same time, the person in charge also emphasized that each person's hair condition is different, and whether silicone oil products are required or not, are different from person to person, and customers can choose according to their own needs. Experts interpret the stability of silicone oil. There is no evidence that it is harmful to the scalp. On the one hand, silicone oil faces many accusations in the market. It has even been described by some merchants as “the source of all evils”. On the other hand, it has also been “asylum” by some merchants. Safety is affirmed, what kind of substance is silicone oil? Is there a problem with its security? Dr. Li Zhiliang, from the Dermatology Hospital of the Chinese Academy of Medical Sciences, said that the scientific name of silicone oil is called polydimethylsiloxane. It is a synthetic chemical compound with stable structure and good moisturizing effect. It started 50 years ago. It has been widely used in the field of hair care and skin care, and it is very safe. Talking about the role of silicone oil in shampoo, Li Zhiquan said that this starts with the structure of the hair. The outermost layer of the hair is the scales. The scales are very fragile. The shampoo, combing and hot dyeing will make the scales curl. Starting and opening, this causes the hair to be rough, easy to knot, and combing is very inconvenient. Silicone oil acts as a softener, and its role in shampoo is to fill the gap between the scales and make the hair more Supple, reduce knots and other phenomena. Silicone oil is insoluble in water and easily remains on the scalp. This seems to be the strongest rhetoric against silicone oil. In this regard, Li Zhiquan said that although the physical properties of silicone oil are insoluble in water, silicone oil used in modern care products. They are all modified water-soluble silicone oils, and generally have a small amount of silicone oil in shampoo. There have been such experiments in which different concentrations of silicone oil shampoo are applied to the human scalp, as long as the silicone oil content in the shampoo is not More than 10% will not cause obvious damage to the scalp. However, our current shampoo generally does not exceed 4% of silicone oil. Some experiments have tested the silicone oil content in forty or fifty shampoos. The results show that the concentration of silicone oil in shampoo is generally 2 Between % and 3%. Therefore, under normal circumstances, the scalp does not have a large amount of silicone oil remaining, and causes problems such as clogged pores.

The silicone oil substitute in the silicon-free product may cause allergic problems. The softener used by silicone oil is an important component in shampoo. If the shampoo without softener washes the hair, it will appear dry and knotted. The reporter is investigating. I learned that silicone oil-free shampoos do not contain softeners. Instead, they use some natural ingredients such as vegetable oil and cetyl alcohol instead of silicone oil. Are these alternative ingredients really better than silicone oil? Concord Hospital dermatologist Shu Chang said that from the point of view of allergenicity, because silicone oil is very stable in chemical properties, it is an inert substance, and it is different from small molecules of hapten substances such as perfumes and emulsifiers. There is no clinical report on silicone oil-induced contact allergy. And silicone oil is a polymer structure that is not absorbed by the skin through the skin barrier and does not cause long-term cumulative damage to the skin. The alternative ingredients in silicone-free oil products are mostly natural substances of plant or animal origin, which cater to the current superstitions of organic products and natural sources. In fact, these natural sources have complex composition and stability. Silicone oils, alternative softening ingredients may have problems such as unstable nature, oxidative rancidity, sensitization or acne effects, such as lanolin, vegetable oils, and macromolecular organics contained therein. In general, the natural source of ingredients is not single, not necessarily better than silicone oil, but may cause skin problems such as allergies. Experts suggest that shampoo selection should vary from person to person. Daily care should not be over-care. Carefully observe the shampoo market. It is not difficult to find that the current shampoo products have become more and more subdivided, controlling oil, dandruff, nourishment, Brightening and other products are available, and many brands have also launched men's shampoo. In this regard, hair problem expert, Sino-Japanese Friendship Hospital dermatology doctor Yang Dingquan welcomed, Yang Dingquan said that because each body is different, the scalp environment is not the same, the shampoo requirements are not the same, the current common family share The condition of a bottle of shampoo obviously cannot satisfy everyone's needs. From the perspective of hair care, the shampoo products are more subdivided. If men, women, the elderly and children have their own shampoos, That is naturally the best. For daily hair care, the dermatologist of the Union Hospital gave more practical advice. Shu Chang said that daily hair care is mainly moderate cleaning. In daily life, moderate care is good. Minimize the stimulation and reduction of the scalp. Excessive care. At the same time, in the choice of shampoo, try to choose mild, low-stimulus products, for some people who are intolerant to some components in shampoo, should try to avoid contact with some products that may bring scalp stimulation, if necessary After the hospital has perfected the detection of allergens, carefully avoid contact with sensitizing ingredients in shampoos, including surfactants, emulsifiers, and fragrances. In addition, it is recommended to wash hair and hair care separately, and the all-in-one product may not be suitable for all people.
