Traditional shampoo contains silicone oil, which can clog pores and cause hair loss? Such rumors made the shampoo added with silicone oil lose its favor quickly. As a result, silicone oil free shampoo quickly became popular in the market. Even though the price is much more expensive than silicone oil shampoo, consumers still flock to it. Does this extra money make your hair more beautiful, or do you accidentally pay the IQ tax again?
The scientific name of silicone oil in shampoo is "polydimethylsiloxane". In fact, silicone oil was first added to shampoo to protect hair.

This is because silicone oil has the following characteristics:
1. Silicone oil has viscosity and ductility, and has the effect of smoothing and repairing hair
There are many uneven hair scales on human hair. If the hair scales are damaged, they will rise up, increasing the friction between the hairs, which makes it difficult to comb the hair. Especially for the hair that is often scalded and dyed, the damage of the hair scales is more serious. At this time, silicone oil will play a role. They can attach to the gaps in the hair scales and fill the hair surface, so that the hair is smooth and smooth.

2. Silicone oil can form a protective layer to maintain the moisture content of hair
When washing hair, the protective grease on the hair will also be washed away by water. Some ingredients in the shampoo, such as anionic surfactant, are also easy to cause the hair scales to rise, making the hair coarse and knotty.
In order to improve this situation, the lubricating effect of silicone oil can be used to protect the hair, which is why ancient women used osmanthus oil to comb their hair.

Therefore, silicone oil is not a bad thing. On the contrary, its original intention is to protect hair. Why are people now touting silicone free shampoo?
The study found that silicone oil may indeed have some adverse effects on hair:

As silicone oil is insoluble in water, it is easy to form a film and wrap pores, and a small part of silicone oil in the cleansing products will remain on the hair and scalp, so it can create a soft feeling.
When shampoos containing silicone oil are used for a long time, the amount of silicone oil deposited on the hair increases, the hair follicles may be blocked and cannot be metabolized normally, resulting in more oil after washing, itchy scalp, loss of elasticity of the hair, and even continuous hair loss. However, there are many reasons for hair quality deterioration and hair loss, which can not be all blamed on silicone oil. The accumulation of sebum caused by poor cleanliness and unhealthy living habits may also be the culprit.

How to choose shampoo?
In fact, silicone oil products and silicone oil free products do not simply remove silicone oil from product components.
When silicone oil is not added, amino acids can be used instead. This is an inherent substance of the human body. Hair and skin will not repel it. It is one of the most mild surfactants known at present, and can also meet the needs of cleaning hair.
However, for dry hair that is long and difficult to comb, it is still a better choice to use shampoo containing silicone oil. If the hair volume is small, the hair is thin and soft, or the hair is easy to lose oil, it is recommended to use silicone oil free shampoo to make the hair more fluffy and refreshing.
