Usually, you must not stay up late and eat less greasy food to keep your scalp fresh, but do not wash it every day. That will make the scalp drier and cause more dandruff, and you can also supplement with vitamin B6 B2.

Pityriasis of the scalp (dandruff) is a ** disease caused by Malassezia (a type of fungus). The proliferation of Malassezia on the scalp causes excessive proliferation of the stratum corneum of the scalp, which causes the stratum corneum cells to shed abnormally in the form of white or gray scales, which are called dandruff. The causes of dandruff are usually divided into physiological and pathological.

Dandruff is a product of the metabolism of epidermal cells in the human head. The keratinocytes on the scalp will gradually differentiate from the bottom of the epidermis, and then gradually move to the surface of the scalp, and finally slowly differentiate to form the horn curved plasma on our scalp, and finally these cuticles will fall off under the influence of related body metabolic enzymes, forming tiny particles that cannot be seen with the naked eye. However, if the keratinocytes in our scalp grow abnormally, it will also cause dandruff to increase, and when more stratum corneum cells fall off and stick together, they will become flaky scales that are visible to the naked eye1.

There are many reasons for dandruff. For example, fungal overgrowth can cause a buildup of keratin in the scalp if the scalp metabolism is too fast or the cell maturation process is incomplete. Pityrosporum pityrias, which relies on dead scalp cells to survive, can also multiply, causing keratin to peel off, resulting in a large amount of dandruff.

In addition, excessive or inadequate cleaning can also lead to increased dandruff. Frequent hair washing can dry out the scalp and dehydrate it; However, if you don't wash your hair for a long time, it is easy to breed a large number of danderspores2.

Dandruff is a visible fragment of scalp cell peeling, which is caused by excessive scalp cell peeling, which is like peeling after sunburn.
