"White hair is the hair of wisdom". On the surface, this sentence is a compliment to the gray hair that grows with age, but in fact it praises the life experience that increases with it. wisdom. However, times have changed, and it seems that this sentence can be quoted as comfort to young people who are growing old.
The living environment of modern people has greatly increased the number of people with obvious gray hair after the age of 30. It is also common for people in their 50s to have gray hair; what is even more worrying is that teenagers are also There are a few white hairs scattered among the black hair. Han Yu once said that he was not yet forty and already suffered from premature aging with "gray hair, blurry eyesight, and shaky teeth". But now the gray hair that represents aging has quietly climbed onto the head of the originally carefree young man. What is wrong with our living environment?
Oxidation eats melanin
In fact, juvenile whitening is not true aging. Disease and medication affect the cell metabolism of the dermal papilla to become insufficient. This is what scientists are trying to find a solution to. question. The basic reason for the occurrence of gray hair is that the protein tyrosine in the melanocytes of the hair is oxidized, so that the originally blackened hair does not contain melanin and forms white hair. The affected areas of vitiligo vulgaris, vitiligo, and alopecia areata may develop gray hair due to the oxidation of tyrosine. In addition, free radicals, the common enemy of aging that medical experts have called out in recent years, are also the main cause of gray hair.
Free radicals are by-products of human respiratory metabolism. Their powerful destructive effects can attack proteins, lipids, nucleic acids, and polysaccharides, causing cell disease, changing DNA genetic information, and promoting aging. In addition to self-generated free radicals, elements that excite free radicals exist in the air, water, food, radiation, drugs, pesticides, preservatives, cigarettes, carbon monoxide, carbon dioxide and ultraviolet rays in sunlight in our living environment.
The oxidation of free radicals causes the tyrosine of melanocytes to mutate and produce gray hair. Originally, the cleaning enzymes of our immune system will automatically eliminate free radicals and inhibit gray hair; however, aging, disease , stress, and adverse environment have offset the power of body-cleaning enzymes, requiring external supplementation. For example, foods containing anti-free radicals, vitamins E, C, B carotene, etc. can eliminate free radicals and prevent premature gray hair. Excessive hormones
The hair is getting less and less, and the face is getting worse. Although men in Tongshan Zhuozuo may laugh at themselves for their growing reputation, they cannot ignore the fact that their hair is getting less and less. They may have tried various methods, such as hair transplantation, and have also used various hair growth agents, spending a lot of money and time. However, it does not start from the basic problem; in fact, hair loss is almost a male exclusive product, because most baldness is directly or indirectly related to excessive male hormones.
After male hormones enter the hair mother cells of the hair root, the cell division of the hair root stops. At first, the hair becomes thinner, and then falls off. Finally, the smooth scalp is exposed, the pores are closed, and the hair mother cells enter the suspended animation period. Excessive male hormones are not the only cause of death for hair. When there is a problem with the hormone receptors of the cells, too much male hormones will enter the hair mother cells. Therefore, the main cause of baldness is genetic constitution.
Because the amount of male hormones is only 1/20 of that of men, women are less likely to suffer from hair loss. However, if their body type is characterized by excessive secretion of male hormones and the problem of receptor mutation, although they will not be completely bald, their hair will still be thin and soft. , sparse. Most of the boys born to such women will inherit baldness.
Excessive male hormone secretion means that sebum secretion is also strong. Sebum will clog pores, causing hair root hypoxia, insufficient blood supply, and malnutrition of scalp tissue, resulting in incomplete hair hardening and weak hair quality. The sebum on the surface of the scalp will also adhere to dust and bacteria. If it is not kept clean enough, it will cause inflammation of the hair matrix, further affecting the splitting of the hair roots and worsening the baldness problem.
Prevent Baldness
There are basic maintenance methods to prevent and suppress baldness, which are simple and feasible, as long as you are persistent and diligent.
First: Massage your scalp. Massage promotes blood circulation and supplies sufficient nutrients to hair mother cells. For 5 minutes a day, use your fingertips to draw a small circle from the hairline to the center of the head; you can also knead or lightly tap; if you have frequent shoulder and neck pain, it means that the blood supply to the head is insufficient. Don’t forget to pinch your shoulders and neck to increase blood flow to your head.
Second: Medicine and food have the same origin. Eating good food is good for scalp health and prevents hair loss. Eat less animal fat, high-fat foods, and sweets to avoid stimulating male hormone secretion.
Eat more kelp and other trace elements that are rich in trace elements to promote hair development. In addition, the main component of hair is protein, and fish, beans, and dairy products with ideal protein structures are also highly absorbed and utilized, helping to grow healthy hair.
When I use my brain too much, I always feel itchy on my scalp. I scratch and scratch unconsciously, and I get dandruff all over my shoulders. Using a cooling shampoo can suppress itchiness; however, when dandruff is excessive, think about whether there is too much oil in the scalp, the shampoo has not been rinsed thoroughly, or the scalp regeneration cycle is too fast? When choosing a shampoo to suppress dandruff, be careful not to use the same brand for a long time to avoid dependence.
Dandruff and itchiness can also occur if the scalp is too dry. This can be improved by reducing the frequency of hair washing and adding conditioners that moisturize the scalp.
Excessive and frequent brain activity keeps capillaries in a state of excitement and expansion, which affects the normal operation of the scalp and hair, causing damage to the scalp and hair. The basic maintenance methods are still massage and nutritionally balanced food. In addition, caring in life is also a good way to care for hair; for example, cleaning bedding frequently and choosing soft fibers with antibacterial properties and breathability are details that cannot be ignored to maintain the health of the scalp and hair.
