. . . For some people, it's an oily system, and so am I. As long as I don't wash my hair for more than 2 days, my hair will turn oily. I also looked for the reason. There are several reasons: 1/ Incorrect living and eating habits; 2. Excessive use of chemical hairdressing products; 3, the concept of clean hair is incorrect (some elders' concept is that they can't wash their hair often, they even tell the younger generation that washing their hair often will cause migraine, in fact, this statement is wrong. If you think your hair is starting to get oily, this is a reminder.

It's time to wash your hair, especially for girls with long hair, even if you wash your hair twice a day. The pressure is too great, I hope it will help you.
