What is the meaning of silicone-free oil? It has been washed for so many years.


Silicone oil (polydimethylsiloxane) is added to the shampoo to provide a softening effect on the hair. However, it is insoluble in water. If it is added to shampoo, it will still adhere to the hair when it is washed, and it will easily form a film and wrap the pores.

However, long-term use of shampoo containing silicone oil, hair will lose elasticity, hair follicles are blocked and can not be normally metabolized.








Due to the impermeability and inertness of silicon itself, when the silicone oil shampoo is used for cleaning again, the silicone oil that has been coated on the hair can not be completely cleaned, but the problem will increase with the increase of the number of uses. The more serious, even the symptoms of scalp hair follicle blockage, hair loss, hair loss, scalp itching.

The production of dandruff is independent of the frequency of shampooing


Quite a few people think that the production of dandruff is caused by shampooing; the rest think that dandruff is caused by insufficient scalp.


In fact, the generation of dandruff is not directly related to the frequency of shampooing. The replacement period of normal scalp cells is 28 days, and after the dandruff cells are fully mature, they are exfoliated by tiny cells that are invisible to the naked eye. When the immature cells reach the top of the skin, they are peeled off by visible fragments, forming dandruff.


One expert said that in fact, more than 90% of people are physiological dandruff, which is produced by normal metabolism. All they need is healthy daily care. "The frequency of shampooing is not too high, and it can be done two or three times a week."
