There is a saying about shampoo, and it quickly occupied everyone's field of vision, that is, shampoo with silicone oil is very harmful, and shampoo should be selected without silicone oil.So is this really the case?This is the topic we want to talk about today!The pros and cons of non-silicone oil shampoo and silicone oil shampoo, good and bad, and how do we choose shampoo.、
Let’s first understand the silicone oil. Silicone oil covers a lot of different annular states. Among the widely used maternity skin care products and shampoo products, it mainly plays a role of conditioning and lubricating. It includes polydimethylsiloxane and polydimethylsiloxane.Methyl siloxane, alcohol amino end, polydimethylsiloxane, etc., the silicone oil in shampoo, the name in the ingredient list is polydimethylsiloxane, which exists in the form of PDMS for short, and the common name of PDMS is dimethylSilicone oil, its chemical properties are stable, and it is not easy to chemically react with other substances. It is a chemical substance that is chemically inert and inactive.Since the 1950s, silicone oils have been added to shampoos and conditioners, and they have been used today.So why should silicone oil be added to the shampoo?
First of all, adding silicone oil to the shampoo can moisturize and protect the hair, resist static electricity, and reduce friction and damage between the hair.Secondly, the silicone oil is adsorbed on the hair to form a protective film, which can protect the moisture content in the hair and stabilize the silicone oil protective layer. Under low humidity conditions, it can prevent the hair from losing moisture.Maintaining a moderate amount of moisture can make the hair easy to comb.Then, the silicone oil is adsorbed on the hair, which can repair the breakage and emptiness between the hair, prevent the hair from breaking and splitting, making the hair stronger, and at the same time making the surface of the hair smoother, so as to reduce the friction caused by the hair when combing.The chance of injury.For many people think that silicone oil will cause hair loss, I want to tell everyone that silicone oil is a colorless, odorless, non-toxic fluid system oil.The molecular structure of the silicone oil in the shampoo has been improved, such as the addition of amino groups, which greatly improves the ability of the silicone oil to adsorb to the hair. At the same time, the water solubility of the silicone oil increases, making it relatively easy to remove.Therefore, the silicone oil in current shampoo products is not as easy to remain on the skin and other parts as you think.Secondly, the content of silicone oil in shampoo is very small, usually less than 1%. With a lot of water rinse, coupled with the action of its cleaning surfactant, the silicone oil adsorbed on the scalp will almost be washed away.Finally, whether silicone oil is irritating to the skin, it is safe as a cosmetic additive. Silicone oil will form a hydrophobic film on the skin, but at the same time it is breathable.As for the silicone-free shampoo.In fact, silicone-free shampoos first appeared in Western countries. This is because Caucasian hair is naturally softer and prefers fluffy hairstyles, so they don’t need to use high conditioning properties, that is, they can make hair smoother.A slippery shampoo, otherwise the silicone oil will deposit on the hair and it will appear to have very little hair volume.But Orientals are mainly the hair quality of Chinese, Japanese and Korean people, which is different from Westerners.Therefore, for a long time, almost all shampoos containing silicone oil have been on the market.So should I switch to silicone-free shampoo?This matter needs to be determined according to personal circumstances. If you are a boy with short hair and do not dye as frequently as girls perm, using a silicone-free shampoo will make your hair more fluffy and keep it longer.If you are a girl with long hair or often perm and dye your hair, it is best to use a shampoo containing silicone oil, which can effectively protect your hair.
