As we age, it is a normal physiological phenomenon to start to appear white hair. Grey hair is caused by the decrease of melanin particles in the medulla and cortex of the hair or the blanks are filled with air.
The pace of life is accelerating, and people are under increasing pressure. Many young people are also starting to grow white hair. In addition, the appearance of white hair is also related to genetic factors.
Sometimes the longer the white hair is, it is not necessarily because of the aging of the body, but because of the lack of nutrition in the body. Today we will learn about what nutrients the body lacks will cause white growth.
Why does gray hair grow longer and longer? You think you are old, remind you: Or you lack 4 nutrients
. Tyrosinase
1 Tyrosinase is the main rate-limiting enzyme in the melanin production process, which helps the synthesis of melanin. The size of enzyme activity can also determine the amount of melanin. When the activity of tyrosinase is reduced, it will affect the synthesis of melanin, resulting in a decrease in melanin, and white hair will appear. The activity of
tyrosinase is related to sunlight irradiation. UV rays entering the skin can enhance the activity of tyrosinase, increase melanin synthesis, and reduce gray hair production.
.Protein
When the human body lacks protein, the hair will fall off faster, it will become dry and lose its luster, the hair will lack nutritional supply for a long time, and hair will be damaged, and gray hair will appear. Therefore, protein must be obtained in time through diet.
. B vitamins
The lack of B vitamins in the body may cause gray hair. B vitamins have the effect of synthesizing melanin. When the human body lacks vitamins, it will lead to a decrease in melanin and gray hair. B vitamins can also help the body tissues use oxygen , promote the oxygen harvest of hair, and help hair health.
. Trace elements
When the body lacks trace elements such as iron, copper, and iodine, it will also lead to gray hair. Iron is the main component of hemoglobin. The lack of iron in the human body can easily lead to symptoms such as iron deficiency anemia and malnutrition, which will cause hair to turn white.
The body lacks copper elements, which will affect the activity of tyrosinase and also affect the metabolic function, resulting in a decrease in the number of tyrosinases and a decrease in activity.
When the body lacks iodine, it may also cause white growth. Iodine can not only maintain the normal thyroid of , but also maintain hair health. The lack of iodine will lead to reduced melanin secretion, decreased hair follicle function, and white hair.
What are the methods to prevent gray hair?
. Ensure the quality of sleep
Ensure adequate sleep, helps prevent white blood growth, adequate sleep helps avoid the body's lack of certain nutrients and improves human immunity. Traditional Chinese medicine believes that from 11 pm to 3 am, blood flows through the liver, and adequate sleep helps healthy liver function and indirectly leads to healthy hair growth.
Develop good routines and go to bed early and get up early can ensure full energy and energy, and reduce gray hair.
. Reasonable exercise
Exercise can speed up the body's metabolism, promote blood flow, and smooth the circulation of qi and blood throughout the body. It helps prevent gray hair. You can do some exercises such as jogging, swimming, playing ball, and dancing square dance.
Exercise can also release stress, relieve mood, and avoid a large number of negative emotions that cause vasospasm of hair follicles and cause gray hair.

. Pay attention to diet
can increase trace elements and nutrients with black effects in the diet. For example, eating black sesame seeds frequently. Black sesame is rich in protein, vitamin A, vitamin E, iron, calcium and other nutrients, which can increase melanin synthesis and avoid white hair.
At the same time, you should also eat more foods containing B vitamins, such as fresh fruits and vegetables, as well as coarse grains and beans. In addition, you can also eat more foods such as beef and mutton, animal liver, etc., which can also help prevent white hair.
