Cause
Seborrheic detachment
The main cause of seborrheic alopecia is that excessive sebum secretion accumulates around the hair follicles, even compressing or clogging the hair follicle pores, creating obstacles to the normal growth of the hair. In addition, oleic acid, linoleic acid, etc. in the sebum secretions are excessive to the hair follicles. It has toxic effects, causing hair poisoning, withering and falling off. Seborrheic alopecia occurs mostly in young adults with strong secretion of sebaceous glands. It gradually begins to lose hair from the top of the head and spreads to the forehead. The scalp is greasy and bright red, and it is yellowish and oily.
1, androgen
Modern medicine has confirmed that seborrheic alopecia has more male hormones, which is mainly caused by the testosterone-derived androgen into the blood circulation, reaching the scalp through transformation to form toxic substances to stimulate hair follicles, hair follicle energy metabolism and protein metabolism disorders. Causes hair to fall off.
2, genetic factors
The genetics of seborrheic alopecia are dominantly inherited in men, and the causative factors can be directly inherited from the previous generation to the next generation, so male alopecia are more common.
Men with a hair loss gene will cause hair loss, while women with alopecia gene are recessive, so there will be no appearance of hair loss and hair loss, unless there are two hair loss genes at the same time. Even if there are two hair loss genes, it will only become thinner for women, and it will not become a big hair loss or leave only marginal hair and a baldness in the middle.
3. Age increases with the age of men
The incidence of liposuction is gradually increasing. The baldness is often found in young men aged 17-20 years. The peak incidence is around 30 years old. Later, with the increase of age, although the incidence rate is reduced, the symptoms are aggravated and eventually become bald.
4. People who are engaged in intense and complicated mental work
The mental stress is high and the brain consumes a lot of energy, which stimulates the adaptation of the body's autonomic nerves and hormones to maintain the normal physiological balance of body temperature, metabolism and immune function, and secrete more androgen, which makes people's analysis and judgment. Power is enhanced, alert and intelligent, and at the same time makes people's temperament more impetuous, sebaceous gland secretion is strong. The sebaceous glands on the scalp are the most developed compared to other parts, and in this case, the secretion is more, which provides conditions for the massive reproduction of the scalp on the fat-rich fungus and head lice. The lipophilic fungus on the scalp is multiplied under the premise of a large amount of sebaceous gland secretion. The catastrophic fungus produces nutrients from the hair follicle and discharges the metabolites there, stimulating chronic inflammation of the hair follicles and scalp - seborrheic dermatitis, lipid If the dermatitis is not treated in time, the roots will grow and reproduce to produce a lytic enzyme, which will dissolve the hair root into incompleteness, loosening the hair roots, gradually shrinking the hair follicles, gradually reducing the hair growth function, and gradually reducing the hair until baldness.
5, head lice is a tiny parasite
It is invisible to the naked eye, and hair experts have found that this fat-loving tiny animal, like the genetic or hormonal imbalance, is also the culprit of hair loss. It is parasitic in human hair follicles. It uses sebum as a food. After eating it, it helps to digest. It secretes a lipase, which further decomposes and erodes the sebaceous glands in the scalp, blocks hair follicles, and makes hair follicles. Lack of nutrients and shrink, causing hair loss or baldness.
Prevention
Seborrheic alopecia prevention
In fact, it is not difficult to treat hair loss, it is related to mood. And to a certain extent, it is also related to the imbalance of certain nutrients in the diet. Therefore, in order to protect the hair, prevent hair loss, small life details should be noted.
First, adjust the mood
Although the discovery of the image does not bring any pain to the physical constitution, it will not cause difficulties for life and work, but its occurrence often increases mental invisible pressure, sleep is not stable, and the diet is uninterested.

Why not?
Second, reasonable intake of nutrients
The occurrence of hair loss is also related to the imbalance of certain nutrients in the diet to some extent. Through long-term practice, it has been recognized that no natural food can contain all the nutrients the body needs, and no single nutrient has a comprehensive nutritional function. For example, milk and eggs are well-known high-quality proteins, but the former lacks iron and the latter lacks vitamin C. Therefore, only through the coordinated cooperation of multiple nutrients can each play its unique nutritional function. In principle, as long as the daily diet includes the following five categories of food:
1, cereals, potatoes, dried beans
2, animal foods such as meat, poultry, eggs, fish, milk, etc.
3. Soybeans and their soy products
4, vegetables, fruits
5, animal and vegetable oils, edible sugar.
And taking turns to use a variety of foods in the same category, you can achieve a complementary role in the nutritional content of various foods.

Excessive online games are also one of the factors that cause male hair loss to become younger. The longer the average computer use per day, the easier it is for men to lose hair. This is related to excessive nervousness. After playing online for a long time, the central nervous system is always in a state of tension, causing autonomic dysfunction, dysfunction of skin vasoconstriction, local vasoconstriction of the scalp, and reduced blood supply, which may cause hair follicle malnutrition and cause hair loss.
2, avoid long swimming
A large amount of bleaching powder is used in the public swimming pool for sterilization, but the bleaching powder has a stimulating effect on the skin. Prolonged contact causes the scalp hair to dry up, and the hair of the seborrheic alopecia is more likely to fall off. Therefore, you should wear a silicone swimming cap for swimming in the public swimming pool, and it is not suitable for long time and damage the hair.
3. Avoid using the computer for a long time

Therefore, you should drink more tea every day to resist the adverse effects of electronic radiation, and also make the skin and hair not easy to age, to prevent hair loss.
4, avoid smoking
Smoking is also a risk factor for hair loss. Experts have found that nearly 70% of people who have hair loss have smoked. However, it is still necessary to further scientifically verify what harmful substances in cigarettes have a destructive effect on hair follicles.

The hair is not sultry, and people wearing hats and helmets will make the hair airtight for a long time and easily suffocate the hair. In particular, the pores of the pores that are pressed by the hat or helmet at the hairline are prone to slack and cause hair loss. Therefore, the ventilation of the hat and helmet should be done well, such as the hollow cap lining on the pad or adding small holes.

8, avoid drinking alcohol
Drinking a lot of alcohol can also cause hair loss, especially spicy white wine, which can cause heat and moisture in the scalp and damage the hair follicles. Even beer and wine, after all, contain alcohol and should be consumed in moderation.

All along, medical textbooks believe that a normal person's daily hair loss is 50-100, which is normal. In fact, a person who does not suffer from hair loss will never happen. According to our study of the number of hair loss, a normal person has a total hair of about 100,000, and about 10% of a person's hair is falling off every year. 365 days a year, the average number of hair loss per day is (100,000 × 10%) ÷ 365 days is about 27, so the average person loses about 20-30 hair per day, and the hair loss season in the fall doubles to 40-50. If someone has more than 50-100 hair loss in a quarter, then your hair is out of order.
