Do normal people really have no dandruff? What is the reason for a lot of dandruff?
Dandruff can be divided into physiological dandruff and pathological dandruff. Pathological dandruff refers to more dandruff caused by dermatitis caused by bacterial infection, fungal infection or other physical and chemical reasons.
Physiological dandruff refers to the common dry dandruff in adults, which is bran-shaped, grayish white and scattered among the hair. There is also oily dandruff. The scalp and hair have a serious greasy feeling with scabs of different thicknesses attached to them. This situation is especially common in babies.
In sebaceous glands, there is a microorganism: Bacillus dandruff, a yeast-like fungus, which normally coexists peacefully with people, but some people suddenly lose their resistance to this microorganism. As a result, the activity of dandruff Bacillus is rampant, and sebum secretion is vigorous to produce dandruff.
Scalp cells also have a normal metabolic process like skin. Cells in the basal layer proliferate, then gradually mature and push out, and finally become lifeless stratum corneum, and finally the stratum corneum falls off.
If there is a problem in this process, so that the scalp cells are not fully mature, they will peel off and produce more dandruff.
For example, the elderly, malnutrition, chemotherapy or psoriasis patients, their dandruff will increase for this reason.
Other causes of dandruff:
1, the shampoo was not cleaned when washing your hair.
2. Use some inferior shampoo with strong degreasing ability.
3. Excessive sebum secretion on the scalp. Too much sebum is mixed with dust and other things, and when it dries, it forms dandruff. Although sebum is small, it will also form dandruff due to abnormal proliferation of keratinocytes.
4, irregular diet, regular drinking, eating irritating food.
5. Excessive mental stress.
6, serious lack of sleep, too tired.
7. Gastrointestinal dysfunction leads to unbalanced nutrition and lack of vitamins A, B6 and B2.
8. Use some inferior hairdressing products.
9, caused by endocrine disorders.
10, the alternation of seasons leads to the increase of dandruff.
Do normal people really have no dandruff? There are many blood vessels, nerves, sebaceous glands, sweat glands and hair follicles on the scalp, which can provide the needed nutrition for hair.
A healthy scalp usually has the following conditions:
1, no obvious dandruff: Dandruff is the most intuitive manifestation of scalp health. If there is a lot of dandruff, it is usually caused by fungal infection and needs antifungal treatment;
2, the scalp is relaxed but not tight: the scalp has no tightness, and there is no obvious sensitive stimulation when pressing the scalp;
3, not itchy: scalp itching may be excessive oil secretion, or pathogen infection, no matter what the situation, keep the scalp clean;
4. Keep fresh for a long time: A healthy scalp can keep fresh for a long time.
There is a sebum membrane on the outer layer of scalp, which forms a natural defense barrier with normal beneficial bacteria. Once the scalp is sick, it is easy to be infected with bacteria and fungi, which hinders the healthy growth of hair. Therefore, it is recommended to get enough sleep, keep a happy mood, avoid excessive mental stress, eat less greasy and spicy food, eat more fruits and vegetables, use mild shampoo at ordinary times, massage your fingertips properly when washing your hair, and actively go to a professional hospital for treatment if you have hair loss symptoms.
Methods to prevent dandruff:
1, choose a dandruff shampoo that suits you and rinse it off;
2. Avoid excessive fatigue and anxiety;
3. Avoid improper diet;
4. Try to avoid using too alkaline shampoo;
5. Don't burn, dye or scratch your scalp excessively;
6. Keep your hair clean.
If you want hair, you should give scalp nutrition in time.
There are three specific methods:
First, choose some shampoos and hair care products rich in vitamin B emulsion essence or ginseng essence, which are beneficial to hair and can penetrate into hair follicles in a small amount.
The second is physical therapy. That is, comb your hair with a wide tooth comb or massage your scalp with your fingers to stimulate scalp blood circulation.
The third is diet therapy. Eat more walnuts, black sesame seeds, bean products and fruits and vegetables rich in vitamins. These foods can regulate the function of the human body and are also good for scalp hair follicle cells. In addition, excessive hair dyeing and perm are not good for the health of the head skin. Experts from the Scalp Health Research Center advise beauty lovers to dye their hair more than once every six months for the health of your scalp and even your hair.
In addition, beauty salons have not recommended shampoo and hair care products to consumers. They think that it is not only impossible to care for and clean hair, but also more likely to lead to hair loss. However, experts pointed out that the scientific community once thought that shampoo and hair care products had a positive and negative neutralization effect, so shampoo and hair care products could not be mixed together.
In fact, this technical barrier was overcome as early as the late 1980s. Now people don't have to doubt shampoo and hair care products. Their functions and utility should conform to the actual utility.
Finally, although the health of the scalp will not affect the functions of other organs of the body, if you have alopecia, seborrheic dermatitis and desquamation, you should go to the hospital for dermatological examination and treatment.
