A healthy scalp should be "free from dandruff, itchy, greasy and energetic", but most people's scalps are in a sub-health state, such as excessive dandruff, frequent greasy hair and scalp, and serious hair loss. Professor Fan Wei Xin said that many people have experienced dandruff reappearing in a short time after shampooing, and it is impossible to effectively suppress dandruff for a long time. However, greasy scalp provides an ideal growth environment and nutrient source for Malassezia, a close comrade-in-arms of dandruff.
"If you don't know your own situation, use the wrong hair care products and wash your hair every day, instead of relieving dandruff, it will cause more serious scalp problems." Fan Weixin emphasized, "For dandruff, we should not simply increase the frequency of shampooing, but choose the appropriate shampoo and hair care products to maintain the appropriate frequency of shampooing. Improper cleaning will excessively remove the lipids on the scalp hair surface, and then destroy the skin barrier and hair scales, resulting in damage to the skin and hair, dull and dry hair, dandruff, itching and other symptoms on the scalp, thus forming a bad cycle of skin secretion.

Professor Fan Wei said that dandruff is the shedding of epidermal cells, which is a clinical manifestation, and does not necessarily mean getting sick. There are internal reasons for dandruff, such as the pressure of work and life, and the mental stress of people, and the scalp condition is directly related to the mental state and immune state, so the scalp will have problems, causing dandruff, dermatitis, psoriasis and so on. Therefore, maintaining a good mentality, mental state and regular living habits is helpful to keep the scalp healthy.
Professor Fan also added that the occurrence of dandruff is nothing more than many external reasons, such as environmental pollution, scalp injury such as PM2.5; There are still many netizens who love to "toss" their hair. Dyeing hair, straightening and perming will do some harm to the scalp.
Professor Fan reminded consumers: "Generally, in supermarkets, shampoo counters have some dandruff test boards with black background. The test board comes with glue and gently leans against the hair, and dandruff leans against the board. According to the distribution of dandruff spots, the severity of dandruff can be divided into grade one, grade two and grade three. One or two of them are mild, and dandruff can be reduced by choosing suitable shampoo, adjusting the pace of life and increasing the number of shampoos. Mild patients have not improved after one or two months of adjustment, and there are third-grade patients. It is recommended to see a dermatologist to see if there are any skin diseases. "
