Now shampoo is also a lot of tricks, but also no silicone oil, but also amino acids, social media, star up people are also crazy on the grass, the price is much more expensive than ordinary shampoo, the effect varies from person to person. No silicone oil, amino acids, is this the product of the pursuit of differentiated competition or is it really good for the scalp?




Since the beginning of a source of publicity of the benefits of silicone-free shampoo on the scalp, my shampoo market is now almost monopolized by the word “silicone-free”. The merchant said that silicone oil is easy to clog the pores and damage the scalp. It seems that there is no silicone oil shampoo. I am not far from greasy and bald.




In the past two years, an amino acid shampoo has been gaining momentum. The amino acid's appeal is closer to the skin's pH, the foam is more delicate, and it can better remove dandruff while also making the scalp milder. Amino acid facial cleanser is also the main point of these two points, so it seems that amino acid shampoo is really good.




Here's what you know is silicone-free and amino acid shampoo


Silicone-free shampoo


Silicone oil is generally referred to as polydimethylsiloxane (PDMS) in cosmetics, commonly known as "silicon spirit". It is non-toxic, odorless, tasteless and is often used as a film former and emollient in cosmetics. Its chemical bonds are flexible, easy to move, and have low surface tension, so it can be smooth. It is also waterproof but breathable. It is an indispensable raw material in many industries and is widely used in skin care products and cosmetics and shampoos. Silicone-free shampoo refers to silicone oils (such as polydimethylsiloxane, dimethiconol, ammonia-terminated polydimethylsiloxane, etc.) in the ingredient list.




Its structure is very stable, it is not easy to degrade, and it is not easy to react with other substances under normal conditions. In other words, it is hardly absorbed by the skin. Since it will not be absorbed by the skin, it will not be carcinogenic as mentioned in some propaganda.


Does the silicone oil clog the pores? There is currently no direct evidence that silicone oil can clog pores. Since it won't clog the pores, you say it is more untenable because it causes hair loss caused by clogged pores. The main function of silicone oil in shampoo is to fill the gaps of the hair scales, reduce the friction between the hair, and make the hair smoother.




However, some people who are greasy and have little hair and collapse do need to use a silicone-free shampoo. Because there is no smoothing effect of silicone oil, the hair can become fluffy and look like a lot. However, if you are dry or neutral, you should be cautious of silicone-free shampoo, because the small hair of the neutral hair has been used because of the use of silicone-free shampoo, resulting in a mess of hair dry hair, using the hair mask Can not save back (because a lot of conditioner, hair mask is also propaganda without silicone oil, tears TT), until unintentionally replaced silicone oil shampoo, hair quality returned to normal.




The amino acid is a surfactant (the surfactant acts as a cleaning agent), and the solution is weakly acidic, similar to the skin, so the stimulation is small. Therefore, amino acid products are indeed reducing scalp damage, and amino acids can blend the polysaccharides on the skin and hair surface, and form a film on the surface of the skin, thus achieving a water-locking function. After washing, the hair will be more moist. . However, the cleansing power of amino acids is relatively weak. After all, fish and bear's paw can't have both. If you want to use amino acid shampoo, you have to look at your hair and scalp. If your scalp is sensitive, it is recommended to use amino acid shampoo.




But beware, there are also a lot of pits in the amino acid, maybe you choose to choose pseudo-amino acids. Amino acids are not easy to foam. If some amino acid shampoos say that they are quick and delicate, then you should take a good look at the ingredient list. If these ingredients are relatively high, sodium methyl cocoyl taurate or cocoyl glutamine Potassium acid, sodium cocoyl glutamate, cocoyl glutamic acid TEA salt, lauroyl glutamic acid, potassium cocoyl glycinate, which is a more reliable amino acid surfactant.


Final summary:


Silicone-containing oils, silicone-free oils, and amino acid shampoos have their own advantages and disadvantages. In some cases, they can be interspersed according to the scalp state of that period of time. The above is some of my usual shampoo purchase experience, for your reference only, if there is something wrong, welcome to exchange.
