Silicone frequently appears in the ingredient list of hair care products, becoming a key element to create smooth hair. So, what is the secret of silicone in hair care products to perform the magic of smoothness?
From a molecular level, silicone has a unique structure. Take the common polydimethylsiloxane as an example, its molecular chain is soft and hydrophobic. The hair scales will curl up after being damaged by wind, sun, perm and dyeing in daily life, increasing the friction between the hair, causing the hair to become tangled and frizzy. When the silicone in the hair care product contacts the hair, its molecules can easily spread on the surface of the hair with low surface energy, fill the gaps of the curled hair scales, and make the hair surface smooth and smooth. It's like laying a layer of smooth tiles on the rough ground, so that walking is naturally smooth and unobstructed.
Amino silicone oil in silicone is even more caring for damaged hair. The amino group in its molecule is positively charged under acidic conditions, which can generate electrostatic attraction with the negatively charged damaged hair surface and tightly bind to the hair. At the same time, amino silicone oil can penetrate into the hair, repair damaged structures, and enhance hair elasticity. Moreover, its high refractive index can also increase the luster of hair, making hair shine again and presenting a smooth and shiny visual effect.
In addition, the good film-forming property of silicone also contributes to it. It forms a thin, breathable protective film on the surface of hair, which not only prevents water loss and keeps hair moisturized, but also resists damage to hair from external dust, ultraviolet rays, etc., and maintains the smooth state of hair. This protective film is like putting on invisible protective clothing for hair, always protecting hair.
With its special molecular structure, interaction with hair, and film-forming properties, silicone has unlocked the code of smoothness in hair care products, bringing people the soft and smooth hair they dream of.
