I don't know when to start, there is a saying about shampoo, and quickly occupied everyone's vision, that is, shampoo with silicone oil is very harmful, shampoo should choose silicone-free oil. So is this really the case? Today we will talk about the difference between silicone-free shampoo and silicone shampoo, and how we choose shampoo.




First of all, it is about silicone oil. Silicone oil is actually a big family. It is mainly used for conditioning and lubrication in a wide range of maternity skin care products and shampoo products. It includes polydimethylsiloxane and polydimethylsiloxane. Oxytomane, alcohol ammonia end, polydimethylsiloxane, etc., silicone oil in shampoo, the name in the ingredient list is polydimethylsiloxane, referred to as PDMS form, PDMS common name dimethicone, it It is chemically stable and chemically inert to other substances. It is a chemically inert and inactive chemical. Since the 1950s, silicone oil has been added to shampoo and conditioner products, and it has been used ever since. So why add silicone oil to shampoo?




First, the silicone oil is added to the shampoo to moisturize and protect the hair, antistatic, and reduce frictional damage between the hair. Second, 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, and can avoid hair moisture loss under low humidity conditions. Maintaining moderate moisture can make the hair easier to comb. Third, the silicone oil is adsorbed on the hair, which can repair the broken emptiness between the hairs, avoid the splitting of the hair, make the hair itself stronger, and make the hair surface smoother, thus reducing the hair friction caused by combing. The probability of physical damage.




For many people think that silicone oil will lose hair, I just want to say that everyone thinks too much. First, the molecular structure of the silicone oil in the shampoo has been improved, such as the addition of an amino group, so that the ability of the silicone oil to adsorb to the hair is greatly improved, and the water solubility of the silicone oil is increased, which is relatively easy to remove. Therefore, the silicone oil in shampoo products is not as easy to leave on the skin and other parts as you think. Secondly, the amount of silicone oil in the shampoo is very small, usually below 1%, a large amount of water is washed, and with the cleaning action of the surfactant, the silicone oil adsorbed on the scalp is almost washed away. Finally, silicone oil is not 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, so students can rest assured.




Let's take a look at the silicone-free shampoo. In fact, silicone-free shampoo is the earliest appearance in Western countries. This is because Caucasian hair is naturally soft and prefers a fluffy hair style, so they do not need to use excessive conditioning properties, which can make hair A smoother shampoo, otherwise silicone oil deposits on the hair, showing little hair. But the Orientals are mainly the hair of China, Japan and South Korea, different from Westerners. So for a long time, almost all silicone oil shampoos are on the market.




Tell us what you care about the most, whether you want to change to a silicone-free shampoo. This matter needs to be determined according to individual circumstances. If you are a male student and have short hair and no hair dyed by the girl, using a silicone-free shampoo will make the hair more fluffy and will last longer. If you are a girl with long hair or regular perm hair, it is best to use shampoo with silicone oil to protect your hair.


I hope this article can help you better solve the small confusion of silicone oil shampoo, and choose the right product for daily use.
