In addition, sometimes hair dyeing, unbalanced nutrition and excessive mental stress may also lead to an increase in dandruff. The first two situations mentioned in the previous paragraph are physiological, and the latter two situations are pathological, which is what we usually see. How to judge what causes your dandruff, or need to go to a skin specialist to understand, so as to have targeted treatment.
There are many reasons for dandruff. Some people with dandruff often go to the supermarket to buy various shampoos according to the introduction and publicity of advertisements without knowing the nature of their dandruff. Driven by interests, some manufacturers blow shampoo wonderfully in advertisements. It seems that there will be an immediate effect after using it, and people who have used it often realize that they are exaggerating.
At present, the anti-dandruff shampoos in pharmacies or supermarkets generally have the following types: tar-containing shampoos, which have the functions of cutin generation and itching relief and bacteriostasis, such as Zeta emulsion. Shampoos containing sulfide can not only inhibit sebum secretion, but also produce cutin, such as Rejoice and Pan Ting shampoo. Shampoos containing selenium sulfide also have antibacterial and degreasing effects, such as Hill Dew. Shampoos containing 2% ketoconazole have a strong inhibitory effect on pityrosporum, such as Le Cai lotion. There are shampoos containing salicylic acid, acetic acid, beer and a small amount of corticosteroids. Generally speaking, oily scalp causes more dandruff, so you can use a shampoo containing sulfur and selenium. Psoriasis dandruff can be treated with tar-containing shampoo, dandruff caused by pityrosporum infection, and lotion can be used. There is no absolute limit to the scope of application of these shampoos for dandruff removal. After applying according to the above principles, if the effect is not great, try to change it, and finally you can choose a shampoo that suits you. Because the above shampoos have the functions of removing fat and inhibiting bacteria to a greater or lesser extent, long-term use will inevitably lead to drug resistance. Therefore, after a certain brand of shampoo has been used for a period of time, it feels that the effect is not as good as before, and other brands of dandruff shampoo should be replaced or used alternately, which may have a better effect.
To use dandruff shampoo, it is generally necessary to fully rub and massage the scalp for more than 5 minutes after application, and then rinse it with water. The practice of applying it a little and then washing it off can't play the role of hair care and dandruff removal. After using dandruff shampoo, sometimes some people's hair will become dry, so you can add some conditioner.
In addition, some folk methods for treating dandruff sometimes work well, so try it. 1. Wet your hair with beer./kloc-After more than 0/5 minutes, wash it with clear water, and then wash your hair with ordinary shampoo. Twice a day, you can see the effect in 4 ~ 5 days. 2. Put 2 to 3 spoonfuls of vinegar into warm water (some people add vinegar to water in the same proportion), dye the hair slightly the color of water, then immerse it, wash it repeatedly 10 minutes and then rinse it with water. 3. Other methods, such as washing with lemon juice and water, washing with 3% ~ 5% boric acid solution and a little glycerin, will also achieve certain results.
For stubborn and serious dandruff, it is necessary to see a doctor in dermatology. If sebum secretion is excessive, while using shampoo, it is necessary to add some oral drugs that regulate endocrine or traditional Chinese medicines that clear away heat and toxic materials and remove fire. For serious dandruff caused by pityrosporum infection, some antifungal drugs such as itraconazole and terbinafine can be taken orally for a short time. For dandruff caused by psoriasis, oral tretinoin preparation or traditional Chinese medicine or black light can be used for treatment. In addition, people with more dandruff can also take some vitamins B6, B2 or vitamin B complex, as well as Shierkang. Drugs for reducing sebum secretion, removing dandruff and relieving itching can be used locally, such as sulfur lotion, selenium sulfide lotion, coal tar lotion and compound anti-inflammatory laxatives. In addition, to develop good living habits, wash your hair frequently before going to bed and massage your scalp properly can improve the blood circulation of your head, maintain a balanced and nutritious diet and relax your mind.

The secret of dandruff removal?
1, avoid eating fried, greasy, spicy, alcohol and caffeine, because it will stimulate the increase of head oil and scalp morphology, and should be quit. ?
2. Avoid eating too sweet food. Because hair is alkaline and dessert is acidic, it will affect the acid-base balance in the body and accelerate the formation of scalp. ?
Don't pour shampoo directly on your head. Because no foaming shampoo will cause irritation to the scalp, form the scalp or aggravate the appearance of the scalp, it should be poured on your hands and rubbed into your hair. ?
4. Wash your hair with warm water. Overheated water will stimulate scalp oil secretion, making the head oil more; If the water temperature is too cold, the pores will shrink and the dirt in the hair will not be washed away. Just use warm water of about 20 degrees. ?
5. Don't comb your hair with your nails. Gently massaging the scalp with fingertips can not only increase blood circulation, but also reduce scalp formation. ?
Change the shampoo on the 6th and 7th. Shampoo cleaning is only temporary for hair. After seven days, the scalp will adapt and lose its cleaning effect. It is recommended to buy two shampoos at the same time and use them alternately. ?
7. Chemical products such as gel and hair gel will harm hair, irritate skin and aggravate scalp formation. ?
Dandruff is produced by common skin dirt, that is, the cuticle of epidermis is constantly falling off, which is also the result of metabolism. Dandruff can be divided into physiological dandruff and pathological dandruff.
Too much dandruff and clogged pores will cause hair weakness, which will easily lead to bacterial reproduction, skin irritation and head itching. Pathological dandruff refers to scalp inflammation caused by bacterial infection, bacterial infection or other physical and chemical injuries.
Physiological dandruff
⊙ The average adult usually has dry dander, and tiny chaff-like, gray-white phosphine chips are scattered among the hair.
The other is oily dandruff. The scalp and hair are greasy and sticky, with scabs of different thicknesses attached to them. This situation is especially common in infants.
Causes of 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 irritating food.
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.
9. Endocrine factors are abnormal.
10. Seasonal variation.
Treatment:
1. Eat more foods containing plant protein or vitamins, and eat less sweets, fats and other foods.
2. Choose sulfur mineral therapy drugs or shampoos (containing ZP ingredients), or eat vitamins B2, B6 and other nutrients.
3. Do head massage and use infrared radiation to promote blood circulation.
4. For those with oily hair, wash the scalp frequently, keep the scalp clean and use a hard brush.
5. In severe cases, doctors are needed to treat or guide medication.
Dandruff needs long-term treatment and prevention, so be patient! ! Generally, shampoo for dandruff in the market is effective, but it is not suitable for long-term use and may bring adverse effects. If dandruff is really to be treated, the most important thing is to change the concept of diet and hygiene in daily life, so as to completely eliminate dandruff.
A diet to prevent dandruff
(1) Pay attention to the intake of alkaline food. Scientists have found that excessive dandruff is related to physical fatigue. Fatigue causes some acidic components to remain in the body during metabolism, such as lactic acid, uric acid and phosphoric acid. These acids will change the value of blood, thus causing physical fatigue. At the same time, it also affects the nutrition of the head skin. And eating more alkaline food will make alkaline components (such as calcium, magnesium, zinc, etc. ) Neutralize excessive acidic substances in the body, so that the acid-base can reach a balance. This is not only beneficial to the nutrition of head skin, but also can reduce scalp shedding. Physiologically alkaline foods include fruits, vegetables and honey. You should pay attention to eating more.
(2) Eat more foods rich in vitamins B2 and B6. Vitamin B2 can treat seborrheic dermatitis, and vitamin B6 plays an important role in the normal metabolism of protein and lipids. Foods rich in vitamin B2 include animal liver, kidney, heart, egg yolk, milk, eel, soybean and fresh vegetables. Foods rich in vitamin B6 include wheat germ, yeast and cereals.
(3) Eat less spicy food. Because when dandruff produces more, it will be accompanied by scalp itching, and spicy and irritating food will aggravate scalp itching. Therefore, we should eat less or no peppers, mustard, raw onions, raw garlic, wine and alcoholic beverages.
(4) Eat less high-fat foods, especially oily dandruff. Because of the high fat intake, sebaceous glands will overflow too much sebum, which will make dandruff form faster and aggravate dandruff.
Seborrheic dermatitis often develops when sebaceous glands secrete excessively. In this case, dandruff will continue to occur. It can be said that dandruff is a mild symptom of seborrheic dermatitis, so we must seek professional treatment.
