Dandruff is the product of the metabolism of human head epidermal cells. The epidermal cells of the head begin to form cells at the basal layer, and then progress layer by layer through the process of proliferation and division. As time goes on, cells will gradually form cuticles and become lifeless and seedless.
When the time is ripe, dry dead cells will automatically fall off from the scalp in sheets or scales. This process is often called keratinization, which is also the specific cause of dandruff. When dandruff appears in large quantities, most of them will be accompanied by symptoms such as scalp itching. If proper measures are not taken in time for prevention and control, excessive dandruff will always accompany us, and even lead to hair follicle damage and hair loss in severe cases.
Second, do you have skin diseases if you have more dandruff?
In fact, dandruff is mostly caused by many factors. Dandruff is not necessarily a skin disease. Many external stimuli or internal reasons can also lead to this situation. For example, frequent shampooing, the influence of dandruff Bacillus and the dysfunction of scalp cells will all lead to an increase in dandruff in the human body for a period of time.
Too frequent shampooing will lead to excessive cleaning of the scalp, leading to an emergency reaction of the scalp, secreting more oil to cope with scalp dryness, and then dandruff will increase. As a microorganism, dandruff Bacillus has no effect on the process of dandruff production in the scalp under normal circumstances.
However, when the scalp resistance decreases, dandruff Bacillus will accelerate the secretion of scalp oil, resulting in excessive dandruff. Strictly speaking, this situation can be regarded as a skin disease. However, it must be said that the dysfunction of scalp cells is the root cause of the sudden increase of dandruff in a short period of time, and it is also the internal cause of dandruff.
Of course, smooth and refreshing hair usually increases people's charm, and dandruff over the shoulders will greatly reduce this charm. Therefore, in daily life, on the one hand, we should improve the awareness of head care, on the other hand, we should pay attention to adjusting our own life rules, avoid eating fried, spicy and other foods for a long time, protect the balance of the scalp itself, inhibit the excessive reproduction of related microorganisms, and reduce the probability of a large number of dandruff outbreaks.
