Why add silicone oil to shampoo? This starts with the structure of the hair.

Our hair grows out of the hair follicles of the scalp, and the main component is keratin. Each hair has many hair scales on it. The outermost layer of hair scales is 7-10 layers of dead cells, covering the surface of the hair to protect the hair core, healthy hair scales are complete and fit, so the hair surface is smooth and looks shiny.

During shampooing, the lubricating and protective oil attached to the hair scales will be washed away, and the hair scales will be cocked when combing, which increases the friction between the hairs and easily entangles the hairs, thereby aggravating the damage of the hair scales. If you dye your hair and perm your hair, it will also make the hair scales open and your hair will look dry and dull.

The silicone oil can be adsorbed with the hair to fill the unevenness caused by the bulge of the hair scales, reduce the mutual friction between the hair strands, make the hair easy to comb and have smoothness, and effectively alleviate the damage of the hair.

At the same time, silicone oil is also a skin moisturizing ingredient, which can cover the skin to form a protective layer, prevent skin water dispersion, and is used more in moisturizers.
