Why do 16 or 17 year olds have gray hair

It's normal, as long as it's not too much, it's too sick, it's too sick.

Whiteheads are mostly related to genetics and are not easy**. And the acquired less whiteheads, in addition to the ****, should also strengthen nutrition. Experiments have shown that protein deficiency and high malnutrition are among the leading causes of premature gray hair.

Guiding opinions: It is recommended to eat more foods that nourish blood and kidney to nourish the hair and moisten hair, such as walnuts, black sesame, black dates, black fungus, etc. These foods are rich in protein and trace elements needed for hair growth.

It's called Shonen White, and it will turn black after a while. Intense and stressful studying; Malnutrition; Lack of sleep can affect your hair, so you go to the supermarket and buy some. A lot of people are in the same situation as you now.

There is a chance of lack of vitamins, lack of trace elements will lead to lack of nutrition and ** is not in place, generally the situation is bleeding gums, gray hair, serious may lead to visceral bleeding, of course, there are also genetic reasons, it is recommended that you go to the hospital for further examination!

Gray hair is mainly due to the reduction of melanin particles in the hair medulla and cortex or being filled with air. White hair occurs when the formation of melanin granules in the hair papilla and hair bulb is impaired, or although it is formed, it cannot be transported to the hair due to some factors, so that the melanin granules in the medulla and cortex of the hair are reduced or disappear.

1. Psychological factors.

When people are in a state of anxiety, nervousness, and depression for a long time, the blood circulation and internal environment of the brain will be damaged to a certain extent, resulting in headaches, dizziness, gray hair, and so on.

2. Poor nutritional status.

Long-term deficiency in the diet of copper, cobalt, iron, protein, vegetable oil, vitamin B1, vitamin B2, vitamin B6, etc. will cause hair to turn from black to white.

3. Diseases, drugs and genetics.

Endocrine disorders such as decreased pituitary gland function and hyperthyroidism, wasting diseases such as tuberculosis, typhoid fever, pernicious anemia, and autonomic dysfunction are all causes of hair turning from black to white.

Life and study are too stressful.

I ...... the same thingEh, through years of accumulated experience: 1. Eat more black sesame seeds, melon seeds, fungus, Italian rice kernels, black beans, and long-term conditioning.

2. Go to the hospital and test it with a few hairs, and you can see that it is a lack of nutrition...Heredity...Or some other reason.

3. Some people only have gray hair on the top of their ears, but not on the top of their heads, which seems to be related to the kidneys (like a classmate next to me).

Finally, I hope that you can let your brother go for a check-up, find out the exact cause, recuperate slowly, and wish you an early ** :)

The child's gray hair is first excluded from genetic factors, and the child's condition should be caused by the uneven secretion of pigment in the germinal layer, so some hair follicles grow gray hair. If you accidentally find a gray hair, it may be caused by a small area of the scalp or a point of pores. Pay attention to rest and increase nutrition in your diet.

Adults with gray hair may lack some kind of nutrition, and experts recommend eating hair dense nutrients to supplement hair follicle nutrition to make gray hair black. There are also many things for adults to consider, and their lives are also very stressful, and the chance of natural gray hair will be great. They worry too much, think too much, and their hair wants to go white.

You have to keep a good attitude and build a good spirit.
