What's up silicone? Is silicone free shampoo really easy to use?


Long hair floating seems to be the standard match of the goddess in the eyes of the public, while balding or lack of hair is regarded as a great shame. Its significance to women is far greater than that of men. The dense hair makes women more charming. Therefore, the merchants have grasped the psychology of our consumers. When you are shopping for the shampoo, the staff will suggest you to use the product without silicone oil, and say that the product without silicone oil will not block the hair follicle, which can effectively reduce the hair loss, and has a good effect on dandruff removal and oil control. Is that really the case?


silicone oil


Oil generally refers to organosilicon oil, which is generally dimethylsilicone oil. It is a kind of polysiloxane with different degree of polymerization chain structure. It is made of dimethyldichlorosilane by hydrolysis with water to produce primary polycondensation ring. The ring body is cracked and rectified to produce low ring body. Then the ring body, head sealing agent and catalyst are put together for polycondensation to obtain a variety of mixtures with different degrees of polymerization. After the low boiling matter is removed by vacuum distillation, silicone oil can be produced. That is to say, the polydimethylsiloxane we see in the composition list of shampoo is a kind of high polymer organosilicon compound. Silicone oil is generally colorless (or light yellow), tasteless, non-toxic, non-volatile liquid.


It's a rumor that silicone oil causes hair loss. Silicone oil is a kind of macromolecular material, which will not be absorbed by hair follicles. The content of silicone oil in shampoo is not much. Under the effect of anionic surfactant which plays a role in cleaning and a large number of water washing, almost all of them have been cleaned up and will not remain on the head. Now there are some new components to improve the structure of silicone oil, such as ether formation or amino addition. These new elements have stronger ability of binding to hair and greater water solubility than silicone oil. Products with these new ingredients can adhere more effectively and have fewer residues.






First of all, silicone oil is sticky and malleable, which can moisturize and soften hair. Hair grows from the hair follicles in the scalp. The main component is keratin. There are many uneven scales on each hair. When the hair scale is damaged, it will rise up, which will increase the friction between the hair and cause the hair to tangle together. More friction will aggravate the damage of the hair scale. Especially the damage of hair scales which are often dyed by perm is more serious. When shampooing, the silicone oil in the shampoo can be attached to the pores of the hair scales, so that the hair surface is filled flat, and the hair will feel very smooth.






Secondly, when washing the hair, it will absorb water and expand, moisten and soften, and the protective grease outside the skin will also be washed away. As the raw material of shampoo, anionic surfactant cleans the dirt on the head, but it adsorbs on the hair under the action of water. After the water in the hair is dried, the hair will explode because of the same-sex repulsion. But because the silicone oil will adhere to the hair, the hair will become thicker and heavier, and at the same time, the static electricity between the hair will be reduced, so the hair will not explode after drying. Sometimes there may be some flat people, especially those with short hair or soft hair and few hair. Such people will use silicone oil free hair care products much better.
