An anionic surfactant, which is a raw material for shampoo, cleans the dirty things on the head, but itself adsorbs on the hair under the action of water. After the hair dries, the hair explodes due to the repulsion of the same sex. At this time, if it is combed with a plastic comb, it is easy to generate static electricity. The problem of anions can be solved comprehensively with cations, such as quaternary ammonium salt type cationic surfactants. But these can not solve the problem of hair scale damage. The chemicals used in dyeing and scalding the hair, the heat and the ultraviolet rays of the sun, even hurt the hair. Later it was discovered that oil can solve this problem. Oil makes the hair smooth and reduces hair damage during combing. It can be found that the osmanthus oil and conditioner that people used in the past were mainly oils. PDMS (polydimethylsiloxane) can adhere to the hair well due to its inertness and adsorption, filling the damaged parts of the hair scales, and making the surface of the hair smoother. Hair with a silicone shampoo is brighter, easier to comb, and stronger and smoother. PDMS also stabilizes the hair's moisture content through a formed protective layer.
