When we walk down the street and see those with thick black hair, we will unconsciously cast envious eyes. In fact, this hair is not just a symbol of beauty, it is more like a mirror, reflecting the health of our body.
Human hair growth is like a choreographed dance, which is closely related to the two "dancers" of androgens and growth hormones. Androgens and growth hormones are actively dancing on the big stage of the body, and their performance directly determines the thickness of the hair. Androgens are like a double-edged sword, if they are secreted too vigorously, they are like an out-of-control conductor, which will disrupt the rhythm of hair follicle growth and shorten the hair follicle growth cycle. The originally vigorous hair follicles, under the excessive intervention of androgens, begin to gradually shrink, like flowers that have lost their moisture and nourishment, and become languishing. In the process, the originally healthy and thick hair will gradually degenerate into fine vellus hair, just like the original sturdy high-rise building, which gradually becomes a crumbling small thatched hut, until it finally falls out baldness.
At the same time, growth hormone plays the role of the "big housekeeper" of cell growth and repair in the body. Once the body is sick, the transportation channel of nutrients is like encountering a traffic jam, and there is no way to smoothly supply nutrients to all parts of the body. The "small factory" of hair follicles, due to the lack of sufficient nutritional raw materials, cannot secrete nutritious keratin, just like the factory does not have enough raw materials, and the quality of the products produced is greatly reduced. At this time, the growth rate of the hair will slow down significantly, and the shine will become dull and dull like the sun obscured by dark clouds, and the thickness will be much less than before.
Therefore, the condition of the hair is a vivid portrayal of the individual's physical state. People with thick, shiny hair, like a well-equipped, powered ship that sails more smoothly in a healthy ocean, are more likely to have a healthier body. However, while hair condition is closely linked to health, it is much more complicated to say whether the amount of hair reflects longevity. The length of life is affected by a variety of factors, such as genetics, psychology, environment, living habits, etc., just like ropes, weaving a large net that determines life expectancy. Therefore, there is no way to directly measure the length of life like an accurate ruler, but it is undeniable that there is an inextricable link between hair condition and human health.
In general, healthy people tend to have a higher chance of longevity, and these people tend to have some distinctive features in their hair.
Thick Hair: Healthy "Dense Forest"
For people with thick hair, the blood circulation under the scalp is like a rushing river, continuously delivering sufficient nutrients and oxygen to the scalp and hair follicles. These nutrients and oxygen are like nutrients in the fertile soil, nourishing every hair and allowing them to thrive. Such a person's physical health is generally not bad, just like a building with a solid foundation, which can withstand all kinds of wind and rain.

Supple and shiny: the healthy "beauty of silk"
A person with smooth and shiny hair seems to have a smooth silk horse on his head, exuding a charming brilliance. Behind this, in fact, is a manifestation of sufficient nutritional supply. Moreover, this type of person tends to be in a very good state of mind, like a room full of sunlight, which makes people feel warm and comfortable. When they are physically and mentally healthy, they naturally have a better chance to move towards the door of longevity. Have you tried various methods to make your hair smooth and shiny?
Color Uniformity: A Healthy "Uniform Palette"
Hair color, like a carefully blended palette, is primarily determined by the function of the body's melanocytes. When melanocytes function properly, it's like a skilled painter who is able to color the hair evenly, giving it a natural black color. Black is like a natural parasol that absorbs light and reduces UV damage to the scalp and hair follicles, while it is also a symbol of health and youthfulness, making the whole person look vibrant. Have you noticed that as you get older, some of your hair color starts to become uneven? What health problems could be hidden behind this?
Scalp Health: Healthy "Clean Soil"
For healthy people, the scalp is like a clean and tidy soil, which is not easy to produce oil, and there is very little dandruff. On the other hand, if the scalp is often greasy, dandruff flutters like snowflakes, and the surface is covered with red bumps, it is like the soil is contaminated, it is likely that there is a problem with the body's internal secretion and nutrient supply, and it may also be a manifestation of androgenetic alopecia and seborrheic dermatitis. Do you pay attention to your scalp health? Have you ever had a scalp problem?
A sudden increase in gray hair: the body is sounding an alarm
I believe that many people have had the experience of growing gray hair, and at the beginning, they may only occasionally find one or two, just like a few special trees that have sprung up in the forest, and they don't pay much attention to it. However, when there is a sudden increase in gray hair, it is like a large white forest suddenly appearing in the forest, and this is when it needs to be taken seriously.
There are many reasons for gray hair, and while aging is one of the most common factors, it is not the only culprit. Genetics is like a seed hidden in genes that may suddenly sprout at some point, allowing gray hairs to appear on your head early. The mental factor is also like an invisible "killer", being in a state of excessive stress for a long time, like having a mountain on your head, which can also lead to white hair. In addition, some chronic diseases and tyrosinase deficiencies may also affect the color of hair unknowingly.
In addition to these physiological factors, when there is a sudden increase in gray hair, we also need to pay attention to the deficiency of the following three nutrients.
B Vitamins: The "Little Helper" of Melanin Synthesis
The synthesis of melanin is inseparable from the help of sufficient B vitamins, which is like a hard-working little assistant and plays an important role in the process of melanin synthesis. However, the body is unable to produce B vitamins on its own and can only be obtained through diet. Long-term vegetarians, like picky eaters, tend to miss out on a lot of foods rich in B vitamins. People with diabetes, as well as those who are taking hypoglycemic medications, can also have their body's absorption and utilization of B vitamins affected. When B vitamins are deficient, the melanocytes in the hair follicles are like soldiers who have lost their command and cannot function properly, and the hair naturally begins to turn gray. If you suspect that you are deficient in B vitamins, you can take medication to supplement under the guidance of your doctor, or you can eat more foods rich in B vitamins in your daily life, such as bananas, which are like a small yellow key that opens the door to B vitamin supplements for you; And oranges, which are sweet and sour juices, are also rich in B vitamins. Do you eat these B vitamin-rich foods regularly?
Protein: the "building material" of hair
Protein is an important building block for hair, just as bricks are the building blocks for a house. If the human body lacks protein, just like building a house without bricks, the hair will become brittle and brittle, and even gray hair and hair loss will occur. Many people choose only a small part of the food world due to poor eating habits such as picky eating and picky eating, which can easily lead to insufficient protein intake, which in turn leads to malnutrition. Therefore, in our daily diet, we should pay attention to the diversity of our intake, and eat a little bit of all kinds of foods, so as to provide sufficient protein for the body and keep our hair healthy. Do you usually pay attention to the variety of your diet and ensure your protein intake?
Trace elements copper and iron: "catalysts" for melanin synthesis
The melanin needed for hair also needs trace elements such as iron and copper to help synthesize, which act as catalysts in chemical reactions and can accelerate the production of melanin. When the human body is deficient in these two trace elements, the amount of nickel in the hair will increase, just like impurities mixed in the otherwise clear water, and the hair color is more likely to turn gray. If you want to supplement trace elements such as copper and iron, we can eat more black fungus, which is like a small black ear, rich in trace elements; Animal liver is also a good choice, it is like a treasure trove of nutrients, storing a lot of iron; There are also sesame seeds and nuts, which also contain a lot of energy in their small bodies, which are good helpers for supplementing trace elements. Do you know what other foods are rich in trace elements such as copper and iron? Share it with everyone in the comment area.
Eyebrows: More than just a beautiful embellishment
We all know that eyebrows play a vital role in facial retouching, it is like the border of a painting, which can make the whole person's facial features look more harmonious. However, you may not know that the eyebrows, a small part of the body, can also reflect a certain amount of health, and even in the concept of the older generation, it is inextricably linked to longevity.
As the saying goes, "A long eyebrow is better than 10,000 loads of grain", and in this saying, people's beautiful yearning for longevity is like lighting a lamp of hope in the dark. In the concept of the older generation, the change of eyebrows seems to contain the code of blessing and longevity. So, is it true that the longer the eyebrows, the longer they live?
In order to unravel this mystery, researchers from the Changsha Institute of Geriatrics conducted an in-depth study. They are like a group of brave explorers who embark on a journey to discover the mysteries of health. The researchers recruited 600 elderly people and divided them into two groups, one was a longevity group of 90 to 109 years old, and the other was a control group of 60 to 69 years old. Then, they carefully observed and counted the length of the eyebrows of the two groups of elderly people. It's like being in a forest, carefully distinguishing the height of each tree. The results of the study found that no more than 3 in the longevity group had long eyebrows, and among centenarians, only 5 had longer eyebrows. It's like a key that opens the door to a new way of understanding the relationship between eyebrows and longevity, and it turns out that eyebrow length does not directly indicate longevity.
In fact, the growth cycle of the eyebrows is like a small spinning top that rotates rapidly, it is very short, basically every 3-4 months, and it reaches its growth limit when it grows to about 0.4-1.0 cm. However, as we age, the metabolism of the elderly is like an old car, which gradually slows down, and the growth cycle of the eyebrows also becomes longer, which causes the eyebrows to grow longer and longer. Moreover, this condition is more common in men, like a special "accelerator" in the male body. Because male hormones secrete more, due to the influence of hormones, hair growth is lengthened for a long time, and eyebrows become more lush.
Although there is no direct correlation between the length of the eyebrows and the lifespan, some changes in the eyebrows can reflect the signs of some diseases like a keen little detective.
Partial loss of the outer eyebrow: a healthy "red flag"
If you notice a partial loss of the outside of your eyebrows, it could be a health alert from your body. It is often related to thyroid function or anterior pituitary hypofunction. It's like a malfunction of a delicate instrument inside the body, causing an abnormal change in the eyebrows. Have you ever seen someone around you in this situation?
Pale at the base of the eyebrows: a "special mark" of the disease
When the base of the eyebrows is white, it is like putting a white hat on the eyebrows, which is most likely a sign of vitiligo. Vitiligo is a skin condition that affects the color of the skin and hair, causing white patches or whitening of hairs in otherwise normal areas. Therefore, if you find that there is abnormal whitening at the base of your eyebrows, you must pay attention to it and seek medical attention in time. How much do you know about vitiligo?
Dry eyebrows that break easily: "uncomfortable feedback" for the body
Dry eyebrows break easily, like dry twigs that break at the slightest touch. This often means that the lungs are abnormal, and it is often accompanied by symptoms such as coughing, coughing up blood, shortness of breath, etc. Problems with the lungs inside the body are like a malfunction in the core of a machine, which is reflected in the small part of the eyebrows. Have you ever noticed this change in your eyebrows because you are feeling unwell?
