Nowadays, there are many types of shampoo for girls to choose from. Because hair quality varies, the type of shampoo chosen may also be different. Currently, shampoos can roughly be divided into two categories: those containing silicon and those without. Previously, most shampoos contained silicone oil, but later it was claimed that shampoos with silicone oil were not good for the skin. So, what is the difference between silicone-free and silicone-containing shampoos? 
The difference between silicone-free and silicone-containing shampoos 
The obvious difference lies in that one is smooth while the other is a bit rough. The so-called "silicone oil" is a non-volatile liquid silicon. It is mainly a synthetic material - silicate. It can give the product a smooth and silky feel and form a film on the skin, and is usually used in makeup assistance or hair care products to create a smooth texture. Hair washed with silicone-free shampoo is relatively dry and frizzy after use, and needs to be used together with conditioner. However, long-term use will make the hair better. 
Shampoo containing silicone oil usually only brings about short-term immediate effects. The hair feels smooth and slippery after washing because the shampoo contains silicon or dimethicone and other chemical components. These components fill the gaps between the hair scales, thus creating a smooth touch. However, the impermeability and other inert properties of silicon itself can also clog pores, causing the scalp to be prone to itching, and may even lead to subsequent hair loss and baldness. 
What are the advantages and disadvantages of silicone shampoo and silicone-free shampoo respectively? 
The benefits of silicone shampoo: Smooth hair 
The non-toxicity of silicone oil is widely recognized. It can be used in hair care products and has been a mainstream additive for many years. Its role cannot be ignored. For instance, it can fill in the gaps between hair scales, smooth the hair, reduce static electricity caused by friction between hair strands, and make the hair easier to manage. 
The drawbacks of silicone shampoo: Chemical substances, poor health index. 
Silicone oil is a chemical substance and impermeable to water. It shares common properties with other chemical substances. Even if the silicone oil content in shampoo does not exceed the standard, long-term use will, over time, irritate the scalp, leading to hair loss, dryness, and itching. 
The benefits of silicone-free shampoo: healthy and safe. 
Silicone-free shampoo is a type of shampoo that does not irritate the scalp and hair. It can thoroughly clean the dirt in your hair and create a healthy environment for hair growth. Silicone-free shampoo usually has rich and dense foam, which feels very elastic and can penetrate every hair strand, easily providing deep cleansing for the hair. 
Disadvantages of silicone-free shampoo: Fluffy and dry hair. 
The bold choice of a purely natural formula without silicone oil has also brought about the problem of dryness and difficulty in combing after washing. Especially for people with dry hair, using silicone-free products alone makes the hair feel as if it has been electrocuted. Without silicone oil as a lubricant, there will be safer ingredients to reduce the friction between hair strands, such as adding "amino acids", "plant oils", "silk proteins", etc. 
Many girls think that shampoos containing silicone oil are unhealthy and can irritate the scalp. In fact, this idea is completely unnecessary. The content of silicone oil in shampoos is very low. So if you want your hair to be smoother or if you have damaged hair after dyeing or perming, you can choose shampoos with silicone oil. Girls with oily scalps who prefer a refreshing feeling can choose silicone-free shampoos. In fact, both silicone-free and silicone-containing shampoos have their own advantages. The key is to see what kind of hair you have. So when choosing a shampoo, you should choose it based on your hair type.
