Hair growth depends on qi and blood. The blood in the body is sufficient and the operation is relatively stable. Hair can get enough nutrition. Growth will be normal and not prone to whitening. The amount of a black substance in the body is normal when people are young, and it starts to decrease as they get older. Also, as their bodies age, they grow gray hair.
This is a normal physiological phenomenon, but the gray hair grows in different places, which can mean different problems. Where does gray hair grow and where is disease? Growing up on the forehead, temples, and the back of the head, what do they represent? Now let's learn this together.

About gray hair
【Principle of white hair formation】
Pigment cells determine the color of our hair. If the pigment cells die for some reason, or the pigment cannot be produced normally, it will cause our hair to become white or white.
It may be due to personal constitution, some congenital diseases, or some acquired diseases. For example, depending on the individual's genetic constitution, some people may start to have a lot of gray hair from a few years old, which we usually call less gray hair.
It's in his genetics. The melanocytes in his hair are prone to premature death. In short, the formation of gray hair is the apoptosis and destruction of melanocytes, or the failure to produce pigment normally.
What factors can cause gray hair
- Lack of trace elements
When we often do not eat the corresponding trace elements such as copper and iron, it is very likely that our hair will gradually turn gray.
vitamin deficiency
If our hair is deficient in vitamin B1, vitamin B2, and vitamin B, if it is 6, it is likely to cause the symptoms of less gray hair, so we should take these vitamins at ordinary times, so that there will be no less gray hair.
- Excessive mental stress
Because of life. Due to work reasons, more and more young people now feel nervous. In a state of depression, this mental state will cause black hair to turn white.
- Overthinking
In middle age, the body's metabolic capacity declines, and the hair gradually turns gray, which is a normal physiological phenomenon. But gray hair appears at a young age, which is inconsistent with age. Gray hair can also be caused by children overusing their brains. Young people may wish to adjust their mentality, relax more, and exercise more.
- Congenital genetics and diet
White hair patient is in the blood of parents, most children also can have white hair. In addition, if patients eat too much high-fat nutrition, excessive smoking and alcohol in daily life, it will affect the accelerated hardening of blood vessels, destroy blood circulation and melanin secretion in different ways, and make black hair white.
- Disease factors
Diseases associated with decreased pituitary function and hair from black to white have been clinically discovered. .Endocrine disorders, such as hyperthyroidism, tuberculosis, etc. typhoid fever, wasting diseases, such as pernicious anemia, and long-term fever, encephalitis, nervous system diseases, autonomic dysfunction and other diseases.
Can white hair be pulled out?
Long white hair can be removed, and the growth of white hair, especially normal physiological white hair, is related to age growth. At this time, the functions of all organs will be weakened or lost, and the ability of melanocytes to produce melanin will become weaker and weaker, so the hair will become whiter and whiter. So it's okay to pull out a small amount once in a while. I didn't say I pulled more and more.
But frequent hair pulling is not only gray hair, but also stimulates and damages hair follicles. It is prone to inflammation, which affects the growth of these hairs. Therefore, we still do not recommend frequent hair pulling.

Where does gray hair grow and where is disease? What does it mean when it grows on the forehead, temples, and back of the head?
- Forehead gray hair
The food and water ingested by the human body transport nutrients to various parts through digestion and absorption. When there is gray hair on the forehead, it may be a gastrointestinal problem. Many people overeat for emotional or physical reasons, which can lead to an unbalanced diet.
Long-term maintenance of this eating habit will lead to a decline in the function of the spleen and stomach, which cannot be balanced to a certain extent, resulting in gray hair on the forehead. If you want to alleviate this situation, you should match your diet reasonably, eat seven minutes per meal, and eat more food every day to protect your stomach.
- Gray hair on the temples
Gray hair at the temples, deficiency of liver qi. Liver function lesions are very related. The liver is a very important organ in the body, mainly containing qi and blood. In addition to metabolism and detoxification, the liver can also secrete bile, promote digestion and peristalsis, store blood, regulate blood and other functions.
When liver disease occurs, it will affect the discharge of toxins and garbage in the body, increasing the burden on the body. People with poor liver tend to grow gray hair on the temples and show irritability.
- White hair on the back of the head
From the perspective of clinical Chinese medicine, deficiency of kidney qi or extreme deficiency of kidney yin cannot affect various toxins and bacteria in the body and uric acid, urea, protein, water, and various harmful substances in the body, such as ammonia, which are excreted outside the body .
With the operation of blood transport and metabolic functions, it will reach the hair follicles and brain system of the body, resulting in gray hair in the back of the brain. Among them, the main clinical manifestations of insufficiency of kidney qi are insomnia, dreaminess, frequent and urgent urination, malnutrition, and changes in the properties of urine.
03
How to regulate hair graying?
Eat more foods containing melanin, such as black sesame or black beans, mainly boiled.
Maintain a good work and rest routine, and don't stay up too late. When the secretion of melanin is strong, if staying up late excessively affects the metabolism of melanin, it will be difficult to grow black hair.
Hair should be trimmed regularly, hair is too long to produce white hair.
Use weak alkaline shampoo, and some gray hair is also related to shampoo.

Extension: Can white hair turn black?
Whether gray hair will turn black depends on the specific situation. If it is caused by a genetic disease, this white hair cannot be reversed into black hair, such as albinism. There are fewer white heads.
However, if the gray hair is caused by malnutrition or weight loss, through a reasonable diet, supplementing high-protein foods, and eating more foods with high trace elements, the gray hair can be slowly reversed into black hair.
In addition, when white spots appear on the scalp of patients with vitiligo, the hair on the white spots will also turn white. With the control of vitiligo, if the white spots on the scalp turn into normal scalp color, the white hair on the white spots may also turn into black hair.
Patients with mental stress, anxiety, sadness, etc., will also suddenly have graying hair. Therefore, we should pay attention to find the reasons for the graying of the hair, and try to eliminate these reasons. Life should be regular, don't stay up late, pay attention to maintain a normal state of mind, and help restore black hair.
