This is going to start from two aspects. The epidermis of the hair is a scaly substance consisting of 6 to 12 layers of keratinous protein. After shampooing, the scales are opened, resulting in increased friction between the hair, and the hair is easily knotted and visually dry. In the era of silicone oil, shampoo + conditioner is standard. However, there are also silicone oils in conditioners that add lubricity and shine to the hair.




Later, the continuous progress of the chemical industry, people found that silicone oil can also moisturize the hair, so silicone oil is widely used in shampoo. Silicone oil is a macromolecule that is not easily absorbed and will solidify on the hair scales of the hair, making the hair smooth and shiny. This is the later two-in-one shampoo, which can also lubricate the hair without the conditioner.


Silicone oil is harmless to the human body, and most of them are easily washed away by water. But shampoos that are inferior or have excessive silicone oil are not easy to say? First of all, industrial silicone oil for inferior products, the low-cost lubrication effect is quite good, but it is difficult to clean, it is easy to paste on the scalp, clog the pores, forming a bacterial cuticle, the hair will be problematic over time, some people will also cause skin The disease.




Whether the silicone oil is good or not, or the shampoo of the silicone oil is better than the shampoo containing the silicone oil, there is no accurate standard. These are the topics that have been developed in recent years. However, from a scientific point of view, healthy hair or short hair can be washed with shampoo containing silicone oil. If you are dry or soft wounded hair, use it. Better than not. However, it is best not to use shampoo containing silicone oil before perming hair dye.


If you choose a shampoo that does not contain silicone oil, you must use a conditioner, otherwise your hair will be washed more and more dry?
