How dandruff is produced, how dandruff is formed

1. Dandruff produces a lot of oil, and the important cause of dandruff is a parasitism of Malassezia. This is a normal parasite on the human body, which feeds on sebum, and excessive proliferation can lead to dandruff, so people with a lot of oily scalp are more likely to have dandruff.

2. Lack of sleep, sufficient sleep can promote normal metabolism, try to avoid staying up late, it is best to go to bed before 11 o'clock at night.

3. Spicy diet, excessive smoking and alcohol, spicy diet, excessive smoking and alcohol will affect the absorption of nutrients, and harmful substances will affect the body's metabolism after absorption. Therefore, eat more vegetables and fruits, and eat less greasy and sugary foods.

4. When the body is unwell and uncomfortable, it is also easy to have an increase in dandruff, such as gastrointestinal dysfunction, unbalanced nutrition, endocrine disorders, etc., which often lead to changes in the body's hormone levels.

5. Over-cleaning, some people think that dandruff is due to lack of hygiene, so it is wrong to over-shampoo. Overshampooing can lead to dry, dehydrated hair, which can worsen dandruff.

6. Shampoo allergies, some people will find this phenomenon; Dandruff and itching can occur with a certain shampoo, which will be relieved by switching to a different brand. At this time, it is necessary to pay attention to the possibility of shampoo allergies. In addition to this, there are many hair products that can also cause contact dermatitis of the scalp, such as hair dyes, hairspray mousses, etc.

When dandruff appears white or gray scales, it is most likely due to a fungal infection, which is medically known as pityriasis scalp and 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. These scales are large and attach to the surface of the scalp or hair, and can easily fall off onto shoulder clothing when brushed or scratched.

The main cause of dandruff.

1. For physiological reasons, dandruff is produced by the general ** dirt, that is, the continuous peeling surface of the stratum corneum of the epidermis, which is also the result of metabolism.

2. The influence of danderspora fungus, in the part of the distribution of sebaceous glands, there is a kind of dandersporin microorganisms, which normally coexist peacefully with people, but when some people sometimes suddenly lose their resistance to this kind of microorganisms, resulting in dandruff caused by dandersporum secretion.

3. Scalp cell dysfunction, the elderly, malnourished, patients who receive chemical ** or psoriasis will be affected by the metabolic process of scalp cells, resulting in incomplete scalp cell maturation process, resulting in flaky scalp peeling.

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.

Health, health, dandruff, sleep, oil, scalp shaving is ugly, there are 5 reasons for dandruff, which is worth collecting.

The production of dandruff is the general ** dirt, that is, the continuous peeling surface of the stratum corneum of the epidermis, and it is also the result of metabolism.

Dandruff is caused by a dysfunction of the scalp, which is not directly related to the chemical and physical nature of the hair. Dandruff (dry seborrhea, pityriasis pricarisa, or seborrhea scalp) was once thought to be a chronic, non-inflammatory scalp scale, unlike psoriasis and atopic dermatitis. However, other studies have confirmed the presence of inflammation in the epidermis on dandruff.

It has also been suggested that the causes of dandruff are still not fully understood, and there is some debate about the causes of dandruff that may play a role in the development of dandruff, including hormones, metabolic defects, diet, nervous system tension, and inflammation caused by drugs and cosmetics. The more common belief is that Bacillus ovale (pityospqrum

ovale) is a common flora of dandruff, and it is one of the causes of dandruff. Thus, reducing dandruff.

The effective method is to use bacteriostatic agents such as ketacpnazole and selenium

Sulphide and copper pyridine sulfate, e.g. rubbing the scalp with Nizoral lotion containing ketaconazole or selenium-containing ingredients

Sulphide's Selsun shampoo shampoo can reduce the growth of microorganisms on the scalp and effectively control dandruff. In fact, it can be difficult to distinguish between dandruff and seborrheic dermatitis.

When dandruff is present, the stratum corneum is thinner than normal, and the rate of epidermal renewal increases. The transfer of keratinocytes to the epidermis is accelerated, the keratinization is incomplete, and the adhesion of the stratum corneum is reduced, resulting in fragmented dandruff. Dandruff is age-related, dandruff is rare before puberty, generally starts in adolescence, peaks in the 20s, and declines in middle and old age.

Dandruff is more in winter and less in summer. There is no big difference between men and women. Anti-dandruff shampoo is effective in suppressing dandruff.

The production of dandruff is the general ** dirt, that is, the continuous peeling surface of the stratum corneum of the epidermis, which is also the result of metabolism, and dandruff is divided into physiological dandruff and pathological dandruff.
