The appearance of simple dandruff may be due to the following reasons:
There are many sebaceous glands in dry seborrheic skin, which can continuously secrete sebum, prevent water evaporation and protect the skin. If there is too much sebum on the scalp, the exfoliated cells will adhere to the scalp together and become fine dandruff after drying. The main reasons for excessive sebum secretion are emotional stress, bad eating habits, alcoholism, endocrine disorders and so on. In addition, it is also related to vitamin deficiency, metabolic disorder, or local stimulation of scalp by cosmetics, hair dyes, drugs or scratching.
Symptoms: This kind of dandruff is usually very small, like white spots, dense, itchy scalp and dry hair.
Fungi infect the scalp, and the most common microorganism is Pityrosporum ellipticum, which likes to grow in areas with high sebum secretion, such as scalp, nose, eyelids and chest. Symptoms: this kind of dandruff is large, forming white and gray patches on the scalp, with layers of flaky scales on it, and even sticking the hair roots into clusters.
Psoriasis Some patients with psoriasis have scalp lesions, while the skin in other places does not. At this time, it is easy to mistake it for simple dandruff.
Symptoms: white and gray plaques can be seen on the scalp, which will be more prominent than the surrounding skin when touched by hand. Scrape gently with your nails, and fine dander will fall off. Some people say it's like scraping wax drops on a table. After scraping off the dandruff, you will see small blood spots on your skin.
How to prevent excessive dandruff In order to prevent excessive dandruff, we should pay attention to the following problems in our daily life:
Good living habits, adequate sleep, a happy mood and more exercise are all beneficial to skin health. In addition, it is necessary to arrange work and rest reasonably and minimize stress.
Adjust your diet and eat more alkaline foods, such as kelp and seaweed. Always drink fresh milk, beans, fruits and other foods that can moisturize your hair; Eat more foods that clear away heat and detoxify; And eat less stimulating and fried food.
Some people think that washing your hair every day can clean dandruff. In fact, too much shampoo will reduce the thickness of scalp sebum and accelerate sebum secretion, which will naturally lead to dry scalp and excessive dandruff. It is best to wash your hair every four to five days. Combs, pillows and pillow towels should also be kept clean, and it is best not to use combs together.
Choose medicinal shampoo. Many shampoos containing drugs can be used to remove dandruff. Hydroquinone was first used to inhibit staphylococcal infection. Soap and sulfur-containing shampoo are also common methods. In addition, shampoo containing coal tar can also achieve good results, especially when combined with other skin diseases, such as psoriasis and eczema. Now commonly used drugs are as follows:
About 70% to 95% of patients with selenium sulfide dandruff can be completely controlled after using selenium sulfide. Its main function is to kill fungi and inhibit sebum overflow.
Selenium sulfide is very toxic and can only be used externally, not orally. In the treatment, sometimes the hair will be dry due to repeated use, and a few users will lose more hair and turn their hair into dark brown.
Zinc pyrithione is a relatively new drug, which has only been used for about 15 years. So far, no obvious side effects have been found. The anti-dandruff effect is better than that of antibacterial drugs with the same effect, and this drug can also be used to dye hair, and the concentration is generally 0.5 ~ 2%, depending on the dosage form.
Zinc pyrithione sulfate (ZP) is an effective and safe anti-dandruff ingredient, which can not only eliminate pityrosporum, but also reduce the formation of fatty acids, and finally inhibit or prevent dandruff.
Note: No matter what kind of anti-dandruff drug, it will cause irritation to eyes, among which selenium sulfide is the most serious. Avoid drugs entering eyes when using, and be more careful when giving them to children. Not too often, just twice a week.
If it doesn't work, or the scalp becomes dry and greasy, or there is an allergic phenomenon, stop using it immediately.

Because some students around me keep changing dandruff shampoo and medicine, the effect is not good, and I heard that some people have been cured. In short, it is the best policy to find out the causes of dandruff first and then find a way to solve it.
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
Ordinary adults usually have dry dander, and tiny bran-like and gray phosphine is scattered among their 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.
