Why Do I Have Dandruff on My Scalp?

Update Date: 2024-05-23 Source: Network

If we often fail to wash our hair, we will notice a lot of small white flakes appearing on our scalp, which are commonly known as dandruff. The presence of dandruff is a normal process of cell metabolism, occurring when dead scalp cells lead to the formation of flaky tissue. Regular and appropriate cleaning can reduce or avoid the occurrence of dandruff. Dandruff is a product of the metabolism of epidermal cells on the human head. The physiological process of the head epidermis is called keratinization, in which cells are formed from the basal layer, proliferate and divide, gradually move upward, and gradually form keratin, becoming a non-nucleated, lifeless stratum corneum. Dry dead cells automatically fall off in a scaly or flaky form, commonly known as dandruff.

The root cause of dandruff production lies in the disruption of scalp ecological balance. Dandruff is caused by the disruption of scalp ecological balance. In fact, a healthy scalp ecological environment is maintained by three major balances: oil, flora, and metabolic balance. When the secretion of scalp oil is imbalanced, the scalp will become greasy. When the environmental balance of the scalp flora is disrupted, a large number of harmful bacteria proliferate, leading to itching. Excessive metabolism of the scalp stratum corneum leads to the formation of dandruff through shedding. The scalp, as the most important command control center of the human body and a natural barrier for the head, is more fragile and sensitive than even the eyelids, affecting the entire body. Scalp issues cannot be overlooked and require health management. Only through comprehensive, systematic, and scientific conditioning and care of the scalp can we eliminate scalp issues such as oily scalp and maintain a healthy state of the scalp.

The mechanism of dandruff production: Physiological dandruff is produced by the continuous metabolism of our skin, scalp, and epidermal cells. The scalp is smooth, and usually no obvious desquamation is visible. Pathological desquamation, on the other hand, is caused by excessive proliferation of scalp epithelial cells, leading to a series of clinical diseases. Clinically, we classify different diseases based on the amount of dandruff and the morphology of skin lesions. 1. Seborrheic dermatitis: Seborrheic dermatitis is the main cause of dandruff. It often occurs in adults and is manifested as thick oily secretions on the scalp or dry hair. 2. Tinea capitis: It is generally thicker and tightly attached to the scalp, covered with silvery white scales, often distributed in patches. 3. Dry scurf: Caused by microbial infections of the scalp and hair, it manifests as damage to dandruff and hair. Severe cases may be accompanied by inflammatory reactions. It is common in children and is often caused by poor hygiene habits.
