Why do people reach forty, some people have more white hair and some people have almost no white hair?

In addition to genetic factors, there are also mental state factors. If a person is in a state of high tension for a long time, even if he is young, he has already begun to have white hair.

Melanin synthesis in the body is inhibited.

After many people are over 30, the white hair on their heads will increase. With the growth of age, hair will grow longer and faster, and more and more. This is because the cells in our body are aging, and hair belongs to the appendages of our skin cells. In the process of growing up, all organs are facing the problem of decline, and hair is no exception. Our body and my melanin synthesis are restricted, so my hair turns white.

However, not everyone will have white hair. Some people have a lot of white hair, while others have no white hair at all. This is related to personal physical quality, heredity and mental stress. When white hair appears is related to heredity. Some people have white hair in their teens. We call this phenomenon "juvenile baldness". If one parent is bald, then the probability of baldness in children will be very high.

Insufficient nutrition, hair is not nutritious.

In addition, hair also needs certain nutrition to keep healthy. If a person's nutrition can't keep up, melanin can't be synthesized naturally, and it is more prone to white hair. Therefore, you can usually eat more foods that are conducive to the absorption of nutrients in your hair to keep your hair healthy and oily, such as black sesame seeds, walnuts and black fungus. Can make your black hair thicker and longer.

In addition, irregular life and disorder of work and rest schedule are also a very important factor in the appearance of white hair, and staying up late and working and rest schedule is not only prone to white hair, but also hair loss. Traditional Chinese medicine believes that the deficiency of kidney-qi will also lead to premature gray hair loss, because the lack of qi and blood in the human body will slow down the metabolic function of the body and affect the production of melanin.

Everyone's physical condition is different

Emotional and mental stress is also the reason why gray hair appears earlier. Modern people have a faster pace of life and greater work pressure. If they are in a state of anxiety and tension for a long time, it is easy to cause endocrine disorders, white hair is easy to be born early, and hair is easy to fall off. And some people may be depressed or even on the verge of collapse because of some changes, and their hair may turn white overnight.

Improper selection and use of conditioner will also bring some harm to hair, so some people don't need shampoo when they are old, but wash their hair with Taomi water, which can play a role in hair care. Generally speaking, everyone's physical condition is different, and the age of gray hair is different, but as long as you can maintain an optimistic and positive attitude towards life, plus regular work and rest and a healthy diet, you can live a wonderful life regardless of your age.
