So what does a healthy scalp look like? Healthy scalp barrier, scalp sebum and scalp microorganisms are in dynamic balance. You can't see dandruff with naked eyes. Your scalp is refreshing, not greasy or itchy. It's not tight. It's white with fine powder. There are no red spots on your scalp, which proves that your scalp is basically healthy.
If you don't wash your hair for about 7 days, a small piece of aging dead skin keratin on the scalp will mix with sebum secreted by the scalp and dust in the air to form dandruff, which is physiological dandruff and the result of normal metabolism. However, if you don't wash your hair for about 7 days, a lot of oil will accumulate on your scalp, and Malassezia will probably invade your scalp, leading to imbalance of scalp flora, which will easily lead to pathological dandruff and scalp itching.
When there is something wrong with the scalp, it is difficult to find that there is something wrong with the scalp, even if there is little red dot on the scalp. So pay attention to the daily care of the scalp. Only when the scalp is healthy can the hair grow healthily. But there is something wrong with the scalp, which will naturally affect the hair. If you want to have a thick and shiny hair, you should first pay attention to the maintenance of the scalp.
