First, the scalp problem: a 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. Hair oil, itchy head, excessive dandruff, dry hair and alopecia are all scalp problems caused by the imbalance of scalp ecological environment, so the scalp is very anti-aging.
1, scalp oil: Some people's scalp oil glands secrete oil and fatty substances, which quickly spread all over the roots of each hair, that is, the whole scalp. Even if such people just wash their hair, their heads will soon become oily again, which will not only affect their image, but also block the scalp pores for a long time, breed harmful bacteria and seriously destroy the ecological balance of the scalp.
2, itchy head: itchy head, even after washing, it is still itchy, and I can't help scratching from time to time. This is actually a stimulating reaction caused by fungi. Scratching caused by itching will cause further damage to the scalp, making the scalp keratinized to form large dandruff, which is harmful to the health of the scalp.
3. Dandruff is medically called pityriasis scalp, which is a skin disease caused by Malassezia (a fungus). When the naked eye can see dandruff, it means that it is pathological dandruff and the scalp is pathological. Physiological dandruff is produced by continuous metabolism of skin, scalp and epidermal cells. The scalp is smooth and usually no obvious desquamation can be seen. Pathological desquamation is a series of clinical diseases caused by excessive proliferation of scalp epithelial cells. Men's scalp is rich in oil secretion, which is more likely to produce dandruff. The survey shows that the regional problem of dandruff is not obvious, and the recurrence rate is high, while the problems of head itching and head oil have the greatest impact on the work and life of the respondents. In particular, repeated attacks of male dandruff will seriously damage the scalp cell layer and even lead to hair loss.
Second, massage health care: there are many nerve endings on the scalp. Some nerve endings are very close to the brain, and the information on the scalp is easily transmitted to the brain. Finger massage on the scalp can gently stimulate the nerve endings on the scalp and enhance the thinking function of the cerebral cortex through nerve reflex. When people encounter some problems and can't think of a good solution, they often scratch their scalp with their fingers to broaden their thinking and come up with a solution to the problem. Scratching the head is the simplest and relatively simple scalp massage.
I wish you a healthy scalp and pay more attention to head hygiene.
