What is silicone oil? Is it really responsible for hair loss, skin irritation and even cancer? Are the zero-silicone shampoos that consumers pay so much for always suitable? Listen to what the professionals have to say.
1、silicone oil can effectively relieve hair damage
“Silicone oil is a kind of organosiloxane, wash care and cosmetics industry use more for dimethyl silicone oil.” Sun Jie told Science and Technology Daily reporter.
In the chemical industry, silicone oil is actually polydimethylsiloxane, cyclodimethylsiloxane or its derivatives collectively. Silicone oil is a non-volatile, transparent, non-toxic, non-corrosive liquid, chemically stable and safe.
In shampoos, silicone oil, whose scientific name is “polydimethylsiloxane”, has good viscosity and ductility, which means that it is very similar to the oils extracted from natural plants.
Our ancestors originally used natural plant extracts to clean their hair and skin. With the development of the chemical industry and the increasing demand for cleansing products, silicone oils began to be used in shampoo products for 70 years now.
Why should silicone oils be added to shampoos? It starts with the structure of the hair.
Our hair grows out of follicles in the scalp and the main component is keratin. Each hair has a number of hair scales on top. The outermost layer of hair scales for 7-10 layers of dead cells, covering the surface of the hair to protect the core of the hair, healthy scales are complete, service, so the surface of the hair is smooth, looks shiny and bright.
Sun Jie told reporters, in shampooing, attached to the scales on the role of lubrication and protection of oil will be washed away, in combing hair scales will buckle, which increases the friction between the hair, easy to make the hair entangled together, thus exacerbating the damage to the scales. If the hair is dyed and permed, it will also make the scales open, and the hair will look dry and lusterless.
Silicone oil can be adsorbed with the hair to fill the unevenness brought about by the bulging scales, reduce the friction between the hair strands, so that the hair is easy to comb and have a smooth, effective relief of hair damage.
At the same time, silicone oil is also a skin moisturizing ingredient, can be covered in the skin to form a protective layer to prevent the skin moisture loss, in moisturizers used more.
2、washing and care products to buy depending on the hair quality
In recent years, silicone-free shampoo quickly occupied the market, even at a price 5-10 times more expensive than silicone-containing shampoos, consumers still rush.
Intensive advertising, Netflix live with goods “recommended”, the eyes of consumers are focused on silicone-free shampoo, but many consumers have not figured out what silicone-free means, to see others use their own followed. As a result, some people have more serious oil, some people aggravate the scalp dryness and hair splitting.
“Zero-silicone shampoo is also developed by manufacturers to meet the needs of Western consumers, most of the European and American population has soft hair and does not need to add a lot of lubricating grease.” Sun Jie explained, but the yellow hair is hard, many people also often dyeing and perming, so how to choose still depends on the hair.
In addition, even though many products claim that the shampoo without silicone oil, but also added other lubricating vegetable oil ingredients. These vegetable oils also have the potential to clog hair follicles. At the same time, some people may also irritate the scalp after use, resulting in allergic reactions.
