There are so many reasons why men's hair turns gray.

Many men start to have gray hair at a young age. This is mostly caused by extreme stress in life. There are many other reasons. For example, some people have genetic factors, while others have a lack of certain nutrients in the body.

1. Genetic or disease factors

The appearance of gray hair is related to genetics. People who have gray or white hair before they reach old age often have a family history. It is an autosomal dominant inheritance and can also be seen in certain syndromes (such as progeria syndrome, myotonic dystrophy, etc.). In addition, some more serious diseases such as pernicious anemia, hyperthyroidism, cardiovascular disease, tuberculosis, typhoid fever, syphilis, etc. can also cause gray hair.

For this group of people, they can improve the graying of hair by insisting on massaging the scalp. The specific method is: before going to bed and after getting up in the morning, insert the ten fingers of both hands into the hair, rub the scalp from the forehead to the top of the head to the back of the head, and rub the scalp for 2 to 4 minutes each time. It can improve the nutrition of the scalp, regulate the secretion of sebum, promote the blood circulation of the scalp, and enhance the local metabolism.

2. Lack of trace elements such as copper and iron

Research shows that lack of protein and high malnutrition are one of the causes of premature gray hair, especially lack of trace elements such as copper, cobalt, and iron in the diet can also lead to gray hair. In recent years, scientists have found that the pigment particles in the hair contain a mixture of copper and iron. When the hair contains more nickel, it will turn gray. Therefore, trace elements are closely related to the color of hair.

In order to prevent premature graying of hair, you should eat more foods that contain iron and copper. Foods that are high in iron include animal liver, eggs, black fungus, kelp, soybeans, sesame paste, etc.; foods that are high in copper include animal liver, kidneys, shrimps and crabs, nuts, dried apricots, etc.

3. Lack of B vitamins

Medical research has found that the lack of vitamin B1, vitamin B2, and vitamin B6 is also an important cause of premature graying of hair. You should consume more foods rich in B vitamins, such as cereals, beans, animal heart, liver, and kidney, milk, eggs, and green leafy vegetables. Traditional Chinese medicine believes that hair is the residue of blood, and kidneys govern bones, and their beauty lies in hair. It advocates eating more foods that nourish blood and kidneys to blacken and moisturize hair.

4. High pressure at work or in life

Modern people are under great pressure in work and life, and are prone to mental tension, emotional depression, long-term lack of sleep and excessive thinking, which leads to liver and kidney deficiency, qi and blood deficiency, and premature graying of hair.

Therefore, we must learn to reduce stress for ourselves, face life with an optimistic attitude every day, and eliminate mental fatigue through simple exercises such as deep breathing, walking, and relaxation gymnastics. Soaking your feet in warm water after get off work every day also has a significant effect on reducing stress.

In addition, pay attention to maintaining a balanced nutrition, eat less spicy, greasy, fried and other foods; avoid consuming too much sugar, oil, salt, etc.
