Silicone oil is viscous and malleable and has a moisturizing and supple effect on the hair. Hair grows from the hair follicles in the scalp, and the main ingredient is keratin. There are many jagged scales on each hair. When the scales are damaged, they will lift up, which will increase the friction between the hairs, causing the hair to tangled in one piece, and more friction will aggravate the damage of the scales. When shampooing, the silicone oil in the shampoo adheres to the gaps in the scales, filling the surface of the hair and making the hair feel supple.
The purpose of washing hair is to remove dust from the hair and scalp, and wash off more grease. However, when the hair is washed, the hair swells and moistens, and the moisturizing and softening of the hair is also washed away. Silicone oil, an anionic surfactant used as a shampoo material, cleans the dirt on the head and is itself absorbed by the water under the action of water. After the hair is dried, the hair is blown up due to 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 hair, the heat and the ultraviolet rays of the sun damage the hair.
