Why is there dandruff on the head

Dandruff is actually very common in the human body, especially in summer. Some people are more likely to get dandruff than ordinary people. Dandruff may appear when the hair is oily or dirty. Dandruff is small white shapes. In fact, it is dead skin on the human scalp. Generally speaking, when there is a lot of dandruff, we can remedy it by using some special shampoos. So how does dandruff appear on the head?

Dandruff is the product of the metabolism of epidermal cells on the human head. The physiological process of the epidermis of the head is called the keratinization process. The epidermis forms cells from the basal layer, proliferates, divides, and gradually moves to the upper layer. The cells also gradually form keratin and become a nucleus-free, lifeless stratum corneum. The dry dead cells fall off automatically in the form of scales or flakes, which is commonly known as dandruff.

The root cause of dandruff is the destruction of the scalp's ecological balance

Dandruff is caused by the destruction of the ecological balance of the scalp. In fact, a healthy scalp ecological environment is maintained by three major balances: oil, flora, and metabolic balance. When the oil secretion of the scalp is unbalanced, the scalp will become oily; when the scalp flora environment is unbalanced and harmful bacteria multiply in large numbers, itching will occur; and when the scalp stratum corneum metabolizes too quickly and falls off, dandruff is formed.

The scalp is the natural barrier of the head, the most important command and control center of the human body. Its fragility and sensitivity are second only to the eyelids. It can be said that a single move can affect the entire body. Scalp problems should not be underestimated and they also require health management. Only by comprehensive, systematic and scientific conditioning and maintenance of the scalp can we eliminate scalp problems such as oily scalp from the root and maintain the health of the scalp.

Specifically, scalp health management mainly includes three parts: first, to improve scalp care awareness, second, to develop good work and rest habits, and third, to do daily scalp care; only in this way can we achieve the prevention and symptomatic treatment of scalp health problems.

The most abundant bacterial species on the scalp were Propionibacterium and Staphylococcus, and these two species showed a mutual inhibition state and influenced the severity of dandruff. When dandruff is present, the number of Propionibacterium in the nearby scalp decreases and the number of Staphylococci increases compared to a normal scalp. Researchers believe that the sebum on the scalp is one of the food sources for Staphylococcus, while the high water content on the scalp can provide a more suitable environment for the growth of Propionibacterium, thereby reducing dandruff.

Regulating the bacterial balance on the scalp through topical compound sulfur-selenium lotion, especially strengthening Propionibacterium while inhibiting Staphylococcus, would be a potential solution to reduce the severity of dandruff
