Silicone oil plays multiple key roles in shampoo. Its core role revolves around improving hair quality, repairing damage, and enhancing the use experience. It can be analyzed from the following four dimensions.：


1. Fill the hair scales to create a smooth touch
Hair is composed of multiple layers of hair scales. Daily combing, perm dyeing or ultraviolet radiation can cause the hair scales to cocked and damaged, causing the hair to dry and frizzy.Silicone oils (such as polydimethylsiloxane) have a unique molecular structure, which can be evenly attached to the surface of the hair, filling the gaps between the hair scales, and forming a smooth protective film.This feature significantly reduces the friction between the hair, makes the hair easier to comb, and avoids fractures and bifurcations caused by pulling.For example, after using silicone-containing shampoo for dry or damaged hair, you will obviously feel the smooth state of your hair from “knotted and difficult to comb” to “combed to the end”.


2. Locks in water and moisturizes to maintain healthy hair
The protective film of silicone oil can not only reduce friction, but also effectively lock in the internal moisture of the hair and prevent the loss of moisture due to dry environment or high temperature blowing.This function is particularly important for dry hair-it can help hair maintain moderate moisture and avoid roughness and easy breakage caused by lack of water.At the same time, silicone oil can also isolate external moisture and prevent the hair from becoming flat due to excessive moisture absorption in a high humidity environment, thereby maintaining the fluffy feeling of the hairstyle.


3. Enhance luster and enhance visual beauty
The protective film formed by silicone oil on the surface of the hair has a specular reflection effect, which can reflect light more evenly, making the hair look brighter and textured.This kind of gloss is not “false slip”, but is achieved by physically improving the flatness of the hair surface, especially suitable for consumers who pursue a sense of gloss.


4. Antistatic and thermal protection to reduce secondary damage
In the dry season or when using a plastic comb, hair is prone to “frizz” due to static electricity.The antistatic properties of silicone oil can effectively reduce the friction charge between the hair and make the hair more obedient.In addition, silicone oil also has thermal stability, which can form a protective layer when blowing or straightening hair at high temperature, reduce thermal damage and extend hair life.


Scientific recommendations for use
Although silicone oil has significant benefits, it should be used in moderation and cleaned regularly.：


Oily hair: It is recommended to choose low-viscosity silicone oil or with oil-control shampoo to avoid excessive deposition of silicone oil on the scalp and cause flatness.
Regular deep cleansing: After long-term use of silicone oil-containing products, use silicone oil-free shampoo or scalp scrub for deep cleansing to prevent silicone oil residues from affecting scalp breathing.
Individual differences: If you are allergic to silicone oil (such as itching, redness and swelling of the scalp), you need to stop immediately and consult a doctor.
