Long-term use of the same shampoo can easily lead to shampoo antibodies

I believe that many of you have had the same experience as me. When you first start using a new brand of shampoo, your hair feels smooth and flowing after washing, making you "so confident". But after using this brand for a while, you find that it is not effective anymore. Many of you firmly believe that the hair must have developed antibodies to some substance in the shampoo! Oh, no, no, no, folks, this so-called antibody is not suitable for use on hair. So, why does a shampoo lose its effectiveness after using it for a while?

After discussing this issue with beauty editor Xiaowanzi, she told me: "From the perspective of skin care, if you use a certain cosmetic for a long time, you will find that the effect is not as good as before. This is because when you first use it, the skin lacks certain nutrients, and the cosmetics allow the skin to absorb a large amount of nutrients, so it is easy to feel that the effect is very good in a short period of time. But after a period of time, the nutrients in the skin are close to saturation, and the skin's absorption will slow down or even stop. At this time, we can't feel how good the quality is. I guess the same is true for shampoo."

The result of the widow's entanglement:

The so-called "frequent change" of shampoo, the frequency is very worthy of consideration. If you change it every week or half a month, it is really not good. Even if your hair is not crazy, those who buy shampoo frequently will probably go crazy first. Associate Professor Mao believes that the frequency of changing shampoo is difficult to define strictly speaking, but for a brand or type of shampoo, it is acceptable to use one or two bottles before changing it. Changing it three or four times a year is an acceptable frequency.

In addition, Associate Professor Mao asked me to remind the folks that shampoo only has a cleansing effect but no therapeutic effect. Some anti-hair loss, anti-dandruff, etc. shampoos on the market are not effective for everyone. Of course, it does not mean that they are absolutely ineffective. They only have the effect of auxiliary treatment. Therefore, if you have serious scalp problems, you should go to the hospital to see a doctor. Don’t expect the shampoo to be effective!
