Shampoo is a commonly used item in everyone's life. Some shampoos contain silicone oil (polydimethylsiloxane), which makes the hair more supple and shiny. But some manufacturers even use silicone-free oil as a selling point! What kind of substance is this "silicone oil"? I understand your brother in this article for everyone's science.




shampoo


The main role of shampoo is to clean the hair and scalp. An excellent shampoo must first have excellent cleaning ability. Now the shampoo on the market is doing a good job. Surfactants in shampoo are cleansing. There is also a co-surfactant that acts to reduce irritation to the hair when cleaning the hair.




There is also a conditioning agent for conditioning the positive and negative electrodes on the hair to reduce the static phenomenon when combing the hair.


Silicone oil benefits


The softener in shampoo is generally silicone oil, which can be absorbed into the hair scales on the hair to achieve a smoother hair without knotting and reduce the damage to the hair when combing hair.




The disadvantage of silicone oil


One characteristic of silicone oil is that it is insoluble in water and difficult to rinse when washing hair. This is why it can be absorbed on the hair. But also because of this characteristic, silicone oil will remain in the pores of the scalp, causing hair follicles to block, redness, acne, and even hair loss!




Whether you want to "silicone oil"


The above mentioned the benefits and disadvantages of silicone oil, the benefits are good, the disadvantages are terrible, the use of shampoo without silicone oil is actually dependent on your hair.


If your hair is oily, silicone oil is not very effective. It is easier to oil with shampoo containing silicone oil.




If your hair is very dry and the hair is poor, then you should use a shampoo containing silicone oil, because the oil from your scalp is very small, and the silicone oil can't block the pores.


So in general, silicone oil is good or bad, mainly because you should not use it. If the hair is easy to oil, do not use shampoo with silicone oil. Dry hair can be used.
