Silicone oil in shampoo has become a controversial ingredient. Some people say that it clogs pores, and some people say that it causes hair loss. Based on people's psychology, many "silicone-free" shampoos have emerged. How should we treat silicone oil rationally?

1. Will silicone oil really block the scalp and cause hair loss?

Silicon is a material that can be used in daily necessities (such as contact lenses, paper towels/softeners, etc.). Therefore, silicon is a safe and safe ingredient, which is not harmful to the human body, and will not clog pores, or It affects hair follicle metabolism, so regular use will not cause hair loss. But for oily hair, shampoo containing silicone oil may indeed cause scalp plugs, which are fat particles, but this will not affect the health of the scalp and hair.

There are many reasons for hair loss, including endocrine seborrheic dermatitis, alopecia areata caused by mental stress, hair loss caused by medical diseases, postpartum hair loss, insomnia, etc. However, clogged hair follicles are not the cause of hair loss. Hair loss caused by shampoo is relatively rare. .
Moreover, silicone oil is a macromolecular substance that will not be absorbed by hair follicles, and there is not much silicone oil in the shampoo. Under the action of cleaning surfactants, coupled with a lot of water washing, there will be almost no residue, sisters don’t have to Too worried.

2. Why should silicone oil be added to shampoo?

Hair grows from the hair follicles in the scalp, and the main component is keratin. If you zoom in on the hair, the uneven hairy skins (hair scales) are clearly visible, like fish scales. The main function of shampoo is to clean the dirt on the scalp and the attachments on the surface of the hair.

However, water and anionic surfactants used for decontamination will cause a series of changes to the hair: hair strands absorb water and swell, become moist and soft, and the grease that usually adheres to the outer skin of the hair for lubrication and protection is washed away. If there are damaged and raised hair scales, it will increase the friction between the hair, causing the hair to be tangled together when combing, and the mutual friction will aggravate the hair scale damage. This is not over yet. After the anionic surfactant removes the grease, it simply adsorbs on the hair, which creates the connection between the hair and the outside world.

The main function of adding silicone oil to shampoo is to reduce friction, help close the cuticles, avoid roughness, and make hair smoother. Therefore, if this ingredient is removed from the formula of the care product, the product feels dry, and it is reasonable for the hairstyle to collapse.
