everything you need to know SHARE TWEET FAVORIS Proper hair care includes more than just bathing and regular haircuts. To help you better understand the ingredients of care products, we look at silicone below.
What is silicone?
S?iliconre widely es aused in skin and hair care products; however, their presence in shampoos and conditioners has been a controversial issue. In hair care, in particular, silicones are a group of hydrophobic ingredients (waterproof) that act as a "capardine" for the hair, sealing the moisture and leaving the hair smooth, silky and shiny. There are several types of silicone, which differ from each other in terms of application, adhesion and flushing capacity (1). Silicones shield the hair follicle (the outer layer of the hair) and make the hair less porous, while helping to protect it from heat and static electricity (2)
What are the most common silicones?
There are 2 main types of silicone, and specifically:
- dimethicone- and amiodimethiconeDimethicone makes hair shiny, smooth and soft. It also enhances the reflection of light in the hair and reduces frizz. Amiodimethicone is a type of smart silicone that attaches to the hair by repairing damaged parts. It works as follows: when the hair is negatively charged, it causes repulsion creating frizz; as the amino groups have a positive charge, the two compounds are attracted to each other resulting in smooth, beautiful hair. In addition, this type of silicone makes the hair easier to comb, which makes it an ideal addition to conditioners.
Why are silicones used?Silicones are widely used because they do not alter the action of the other components of the composition. This means that they can be easily combined with other emollients or surfactants. In addition, thanks to their extremely mild action, they do not disturb the balance of fiber or hair proteins (keratin). Another reason they are used is because they do not affect other treatments that can be applied to the hair (such as dye). Instead, they repair and prevent the daily stress of the hair, ensuring nourishment and softness to the hair and facilitating their styling.Some consumers prefer silicone-free products as they offer a different end result. The Dercos Detox treatment line, without silicone, leaves the hair light and is ideal for those who prefer products with fewer ingredients. Another case where silicone-free products can be useful is before dyeing, as some hairdressers prefer to apply the hair color as lightly as possible, without the coating created by the silicone.
What is the role of silicones in hair care products?Silicones are incorporated into the composition of care products due to their unique ability to offer hair shine, smoothness and softness. In shampoos, they provide shine and softness to the hair, without weighing it down. They also repel water by creating a light veil that embraces the hair and seals moisture. Their function in the emollient creams is also important, through which they provide the hair with smoothness and softness.The silicones contained in hair care products are safe and tailored to the cosmetic needs and expectations of the consumers to whom the products are addressed.
Why do silicones have a bad reputation?Many people believe that due to their overlapping action, silicones cause accumulation. However, this has not been proven, because silicones, as a component of the composition of care products, do not accumulate in the hair. Another misconception is that silicones have a negative effect on hair or hair. There is no scientific evidence to support this claim.
Do silicones have an impact on the environment?Silicones are safe for consumers, but are not easily biodegradable in the environment. That's why our laboratories are working to identify both new types of silicone that can be used in smaller quantities and have greater biodegradability, as well as alternatives to silicone that offer similar benefits to hair and, at the same time, have less environmental impact.
Do silicones pose health risks?L’Oréal offers safe, effective, and high quality products that you can use with absolute certainty. Today, consumers know exactly what they want and are aware of the ingredients they need to look for. According to studies, in fact, 80% of women answered that they know what their cosmetics contain (3). For L’Oréal, the safety of both the ingredients and the compositions themselves is a prerequisite for all its products. Before being incorporated into each composition, each ingredient must undergo a rigorous safety assessment.SOURCES:
