Why is there more dandruff on the hair?
Question 1: Why does hair always have dandruff? Dandruff, medically known as pityriasis scalp, is a skin disease caused by Malassezia (a fungus). The proliferation of Malassezia on the scalp causes excessive proliferation of the stratum corneum of the scalp, which makes the stratum corneum cells fall off abnormally in the form of white or gray scales, which is dandruff. The causes of dandruff are usually divided into physiological and pathological.

The root of dandruff-the ecological balance of scalp is destroyed.

Dandruff is caused by the destruction of scalp ecological balance. In fact, the healthy scalp ecological environment is maintained by the three major balances of oil, flora and metabolic balance. When the scalp oil secretion is unbalanced, the scalp will produce oil and become greasy; When the scalp flora environment is unbalanced and harmful bacteria multiply in large quantities, head itching will occur; The metabolism of scalp cuticle is too fast, and dandruff is formed when it falls off.

As the most important command and control center of the human body-the natural barrier of the head, the scalp is second only to the eyelids in its fragility and sensitivity, which can be said to affect the whole body. Scalp problem should not be underestimated, and health management is also needed. Only by comprehensive, systematic and scientific conditioning and maintenance of the scalp can we eliminate scalp problems such as scalp oil from the root and keep the scalp healthy and normal.

Specifically, scalp health management mainly includes three parts: first, improving scalp care awareness, second, developing good work and rest habits, and third, doing daily scalp care; Only in this way can the prevention and symptomatic solution of scalp health problems be realized.

Mechanism of dandruff production

Physiological dandruff is produced by the constant metabolism of our skin, scalp and epidermal cells. The scalp is smooth and usually no obvious desquamation can be seen.

Nursing care of dandruff

Pathological desquamation is a series of clinical diseases caused by excessive proliferation of scalp epithelial cells. Clinically, we classify different diseases according to the number of dandruff and the shape of skin lesions.

1. Seborrheic dermatitis: Seborrheic dermatitis is the main cause of dandruff. It often appears in the adult population, showing sticky oily secretions when the scalp or hair is dry.

2, tinea capitis: generally thick and tightly attached to the scalp, the surface is covered with silvery white scales, often distributed in points.

3, dry tinea: caused by microbial infection of scalp and hair, manifested as dandruff and hair damage. Severe cases may be accompanied by inflammatory reaction. Generally common in children, mostly due to poor hygiene habits.

4, atopic dermatitis: manifested as diffuse scalp dryness. Common in children, usually accompanied by dry skin or eczema.

Other bacteria causing malassezia

Shampoo and dandruff removal

Cause of disease:

1. Do not wash the shampoo.

5. Autonomic nerves are easily nervous.

6. Lack of sleep and fatigue.

7. Gastrointestinal disorders, unbalanced nutrition and lack of vitamins A, B6 and B2.

8. Use bad hairdressing products.

Antifungal drugs

It is clinically used to treat dandruff.

Dandruff fungi

Antifungal drugs include ketoconazole, clomizole, selenium disulfide, etc. Ketoconazole has the best effect on dandruff.

Ketoconazole can inhibit the synthesis of ergosterol and the reproduction of Malassezia at low concentration. At high concentration, it directly destroys the cell membrane of fungi, showing strong bactericidal effect. Ketoconazole has a high affinity for scalp protein, and can quickly form a protective film on the scalp surface, thus continuing to play a role. In addition, ketoconazole has no transdermal absorption and high safety.

Epidermal exfoliating agent

Cuticle exfoliating agent can effectively remove a certain proportion of stratum corneum cells and relieve clinical symptoms to some extent. Such products include coal tar, sulfur and salicylic acid. Long-term use of such products will destroy the epidermis structure, disturb the balance of the epidermis itself and affect the hair quality.

Cell growth

Cell growth inhibitors mainly reduce the turnover rate of stratum corneum cells. With the recovery of the cycle length of stratum corneum, the process of keratinization and desquamation has been improved, but many clinical experiments show that these drugs can not control the clinical symptoms of dandruff well. Moreover, its main components are relatively strong, which will make the hair feel rough after use, and may also lead to some beauty problems, especially some sensitive skin, and an odor.

Question 2: What is the cause of dandruff? There are two main forms of dandruff. One is that excessive sebum secretion is mixed with dirty dust, which becomes dandruff when it dries; The other is exfoliated keratinocytes on the scalp surface.

Dandruff looks disgusting, and the culprit behind it is even more disgusting. Now let's find out these culprits one by one.

The biggest culprit-bacteria Under normal circumstances, the natural metabolism of dandruff is not easy to detect, but if the scalp metabolism is too fast or the cell maturation process is incomplete, it will make keratin accumulate. At this time, pityrosporum sp. Feeding on dead scalp cells, a large number of proliferation, resulting in exfoliation, snowflake dandruff.

Too much oil most people are very concerned about whether they are shiny or not, and worry about too much oil on their faces. In fact, there are more sebaceous glands distributed on the scalp than on the face, and the secretion is greater, which is more worthy of your nervousness. Sebum is a good culture medium for dandruff, and the hair is dirty and greasy. It is the most unique environment for dandruff and a hotbed for the growth of bacteria and fungi.

Dermatological patients For some people with eczema, psoriasis and other skin diseases, dandruff is more likely to appear on their hair, and this kind of dandruff is different from ordinary small dandruff, which is large and numerous. If you have a similar situation, you should be careful and check whether you have some skin diseases.

Work stress: Are you sweating or trying to get promoted, earn money and stand out from the crowd? Mental stress, emotional distress, excessive brain use and lack of sleep all put people under pressure, and stress is also an important cause of dandruff.

The production of endocrine disorders dandruff may also be affected by changes in hormone secretion in the body. For example, adolescent women may make you suffer from dandruff before and after menstruation.

* * * Sexual food Eating * * sexual food may also lead to an increase in dandruff, such as fried food, which tastes good, but it is just right for the taste of pityrosporum. Pityrosporum grows vigorously, and dandruff will definitely increase.

Don't think too much that spring breeze and autumn moon are romantic things, and they will also bring you troubles. For example, in spring and autumn, the temperature is hot and cold, which will increase dandruff and greatly reduce your romance.

Nutritional deficiency Many people's dandruff is also related to the lack of B vitamins in the body.

Have you tried it after dyeing your hair and perm? Just a few days after dyeing my hair and perming it, I found dandruff on my hair while camping there. Yes, everything has its advantages and disadvantages. Dandruff is more likely to occur after dyeing your hair and perming it, so that after a few days of beauty, you start to worry about those ugly dandruff.

Food to prevent dandruff dandruff can be divided into dry and oily. Dry hair is the result of insufficient sebum secretion, especially for malnourished people and middle-aged women. It is advisable to eat fatty foods such as animal liver, malt, seaweed, pork and fruit. Oily scalp is mainly caused by the lack of vitamin B group (especially vitamin B 1, vitamin B2, vitamin B3 and vitamin B6), so you should eat more beans, taro, green vegetables and pasta.

Most shampoos contain chemicals, so you must be careful when choosing. Shampoo can be divided into emulsion, paste, powder and block according to different forms. According to the raw materials, there are synthetic and soap-based types. Synthesis, convenient use, rich foam, strong detergency, softness, small size, easy cleaning, not affected by the temperature and water quality of shampoo, can improve the elasticity and luster of hair, and make hair loose and easy to comb. Soap type, high fatty acid content, weak alkalinity, more foam and strong detergency, suitable for oily hair. In principle, it is advisable to choose something suitable for skin and hair properties, especially weakly alkaline. Otherwise, after shampooing, the hair will lose its luster and elasticity and become droopy, which will also cause the hair to turn yellow or red. Dry skin will make the scalp rougher and dandruff increase. It is best not to wash your hair with ordinary soap, because there is a layer of scaly horny tissue on the surface of your hair. If the soap is directly rubbed on the head, it is easy to get stuck in the gap of squamous keratinous tissue, and it is not easy to clean it, which will damage the scalp and hair. You can't wash your hair with soap because soap is more alkaline. If you stay in the gap of scales, the stratum corneum will fall off due to alkaline corrosion, which will greatly increase dandruff and make your hair more vulnerable to damage.

Question 3: What are the causes of dandruff? How to solve it? Dandruff is naturally produced by the metabolism of scalp epidermal cells. The cells that fall off when the scalp is healthy are powder that we can't detect easily. There is something wrong with the scalp. The epidermis falls off before it matures and dandruff appears. Clinically, the increase of dandruff is accompanied by hair loss. Generally speaking, it may be seborrheic dermatitis or psoriasis, and it is necessary to see a dermatological clinic for differential diagnosis. The etiology of psoriasis is unknown. Seborrheic dermatitis is related to bad eating habits, alcoholism, endocrine disorders, lack of vitamins or local scalp contact with cosmetics and hair dyes.

Pay attention to keep enough sleep, be happy and take part in more sports in life; Adjust your diet. Usually you can eat more alkaline foods, such as kelp, seaweed, fresh milk, beans, fruits, etc., and eat less fried foods.

At the same time, it is suggested that you wash your hair every three days, and clean your comb, pillow and pillow towel. Your family had better not use combs. Treat your hair with sulfur ointment.

Method 1: Wash your hair with warm water.

Too cold water can not only wash your hair, but also cause dizziness and headache. On the contrary, overheated water will make the scalp secrete too much oil. So washing your hair with warm water is the most comfortable and healthy.

Method 2: Use conditioner correctly.

I believe that for many girls, conditioner is the most basic maintenance step. In fact, many MM didn't notice it, and the conditioner only needs to be applied to the ends of the hair. If you touch the scalp too much, it will cause the burden on the scalp and produce dandruff.

Method 3: the combination of washing and care is not good.

There are many shampoo products on the market now, but the effect is not as good as it is said. After all, there will be some contradictions when the two are combined. It is better to use scalp and hair separately, so look carefully when buying.

Method 4: Dry your hair after washing it.

Many people like to wash their hair at night, but it should be noted that when we wash our hair at night, we must use a hair dryer to dry it in winter or summer. Because there is still some water on the scalp after washing your hair. This will cause headaches for a long time, but don't blow your hair too dry, which will also produce dandruff.

Method 5: Master the correct shampoo method.

Many people just scratch when washing their hair, but that will only make their hair worse and worse. The correct method of shampooing should be to pour shampoo into the palm of your hand, add a little water and knead it until the foam is rich, and then apply it to your hair. If you want to reduce dandruff, you must master the correct shampoo method.

Method 6: Anti-dandruff products should not be used more.

In fact, dandruff is divided into two categories, one is bacterial and needs to go to the hospital to see a doctor. Another is sensitive dandruff caused by external factors. There are so many desquamation products on the market that you can't use them blindly. After all, those products contain strong alkalinity, and using too much will only make your dandruff more. So it takes patience and time to choose the right anti-dandruff products.

Method 7: * * Scalp dandruff removal is good.

Before going to bed every day, use a comb to gently comb your hair back from your forehead until you have a fever. This can promote the blood circulation of the scalp well, and at the same time comb off the scalp.

Dandruff is the product of scalp metabolism. In addition, the formation of dandruff is closely related to the imbalance of some nutritional elements. In fact, there are many ways to prevent and treat dandruff. By improving diet, the purpose of dandruff can be achieved well.

Question 4: What about dandruff? In fact, everyone has some dandruff more or less, which is divided into dry and oily. Most of the dry hair is loosely distributed on the scalp, and it falls off when combing or scratching the hair, and white or gray scales are scattered on one shoulder; Oily ones stick to hair and exist in the form of oily crumbs, which are not easy to fall off.

There are many reasons for dandruff: excessive sebum secretion is mixed with dust and becomes dandruff after drying; Although sebum is small, it will become dandruff because of the abnormal proliferation of keratinocytes; People with excessive brain use and vigorous metabolism are more likely to produce dandruff; Climate change, lack of sleep, edible food, excessive alcohol and tobacco, abnormal hormones in the body, poor blood circulation, excessive mental stress, indigestion in the stomach, etc. , will produce a lot of dandruff; In addition, scalp desquamation is also related to vitamin B deficiency in the body.

Self-cleaning debris in front of the door

First of all, shampoo

Mild dandruff doesn't need special treatment, and some are just hair gel chips or pills piled up with shampoo. Pay attention to the adjustment of diet structure, keep your head clean, and use shampoo with dandruff removal function, which can play an inhibitory role.

Dandruff shampoo is different from ordinary shampoo. The former belongs to medicated cosmetics or drugs, and should not be used more. Recently, the relevant departments found that many shampoos have added antibacterial ingredients, but the instructions did not indicate the ingredients. If consumers use it every day, it will cause dermatitis and even white hair due to excessive use.

If dandruff is serious, use a special shampoo containing habitat and cadmium. After three weeks, if there is still a lot of dandruff, you should see a dermatologist. Like Xi An Jensen's music collection, it belongs to the pharmaceutical nature and is available in pharmacies; You can also try plant dandruff shampoo such as Xi 'an Dandruff Static and Henan Dandruff King.

The correct way of washing hair is an important part of removing dandruff. Avoid washing your hair with hot water with excessive temperature, and wash your hair with your fingertips to avoid bacterial infection caused by scratching your head. In addition, in the process of shampooing, dandruff can be removed through the scalp, and finally dandruff can be suppressed with dandruff shampoo. You can refer to the following correct shampooing procedures:

1. Comb your hair thoroughly before shampooing, which helps to prevent your hair from knotting and falling off when shampooing.

2. Apply the gel to the scalp, let it stand for 10 minute. This can deeply clean the scalp, remove dandruff and inhibit the excessive reproduction of bacteria and microorganisms.

3. Soak the hair completely with warm water from scalp to hair end. Take a proper amount of shampoo and pour it on the palm of your hand, not directly on the scalp. Shampoo is added with water, kneaded into foam and then washed into scalp and hair.

4. Back and forth on the scalp with fingertips can promote the blood circulation of the scalp and remove waste keratin and oil stains. Then wash your hair thoroughly with warm water.

5. Apply conditioner at the end of hair to increase the elasticity and protective film of hair. Rinse your hair carefully with warm water, because it is very harmful to your hair.

6. Gently press the hair with a dry towel, and never rub the fragile hair roughly.

7. In addition to cleaning the scalp, spray emulsion can also inhibit dandruff and maintain hair. Because it has the effects of purifying, anti-allergic and rebuilding hair elasticity, it can provide comprehensive care for hair with twice the result with half the effort.

8. Using scalp conditioner * * * can help to prevent and prevent the recurrence of dandruff, at the same time, it can increase the luster of hair and give plants a fragrance. As long as simple and effective actions can achieve the goal.

9. When you blow your hair with a hair dryer, don't blow your hair directly at high temperature. When it is eight minutes dry, it can provide enough rest space for the hair. If you want to blow out a beautiful hairstyle, you can also blow out a soft shape with a hair comb when it is dry in seven or eight minutes.

Second, * * * *

In addition to simple daily care and scalp treatment, * * * can also increase the skin temperature of the head, accelerate blood circulation and metabolism, and make the trachea attached to the scalp such as sebaceous glands, sweat glands and hair follicles function normally, thus reducing dandruff.

Method A: Bilateral or unilateral fingers and palms rotate back and forth from the forehead hairline to the occipital shell until the scalp feels hot.

Method B: Put one hand together at a 90-degree angle and pat it back gently from the hairline to make the head feel relaxed.

Third, diet therapy.

It is said that medicine tonic is not as good as food tonic, and so is the treatment of dandruff. In the daily diet, eat more foods containing vitamin B and alkaline foods, and reduce dandruff by balancing the acidic components harmful to the head skin. At the same time, try to avoid coffee and acidic foods with high sugar content.

Vitamin B is the key to the release of energy from food, and it is also an essential substance for human tissues. Lean meat >>

Question 7: What is the reason for dandruff in hair? Hello, my friend, what causes dandruff?

The influence of dandruff Bacillus

There is a microorganism called PITYRO-SPORUMOVALE in the sebaceous gland, which is a yeast-like fungus. Under normal circumstances, it coexists peacefully with people, but some people will suddenly lose their resistance to this microorganism. Bacillus dandruff can make sebum secretion exuberant and produce dandruff.

Dysfunction of scalp cells

Scalp cells also have a certain metabolic process like skin. After the cells in the basal layer proliferate, they gradually mature and push out, and finally the stratum corneum becomes lifeless and falls off. If there is a problem with this process, it is that the maturation process of scalp cells is incomplete. In other words, it will peel off. For example, the elderly, malnutrition, chemotherapy or psoriasis patients, the increase of dandruff is caused by this.

Other reasons are as follows:

1. Shampoo is not cleaned.

2. Use inferior shampoo with strong degreasing power.

3. Excessive scalp sebum.

4. Improper diet, drinking and sexual food.

5. Autonomic nerves are easily nervous.
