Yellow hair may be a calcium deficiency.

Everyone knows that infants, nursing mothers and the elderly are prone to calcium deficiency, while adolescent boys and girls are prone to calcium deficiency, but little is known

After entering puberty, it is the second surge period of the human body, and the fast growth can grow 7 to 8 cm taller in a year, and the weight can increase to 4 kg. Generally speaking, you can "grow meat" with anything you eat, but bones must be calcium, and you can't grow bones without calcium. Therefore, the calcium requirement during adolescence is particularly high.

Adolescents who study indoors all year round and have less sunlight are prone to calcium deficiency. Because the ultraviolet rays in the sunlight can promote the absorption of calcium, without ultraviolet radiation, no matter how much calcium you eat, you will not grow into bones

Calcium deficiency in adolescence is mainly manifested by night sweats, that is, sweating while sleeping; Hair is few, dull, and burnt yellow; Cramps in the calves (gastrocnemius muscles) when you sleep at night. To prevent and treat calcium deficiency in adolescence, the following should be done

1. Take calcium-containing drinks or medicines. Such as taking active calcium powder or calcium lactate, multivitamin calcium, etc. It should be noted that after taking calcium products continuously for more than ten days, stop eating for 1 week, and then continue to eat, or within 1 week, eat for 3 to 4 days in a row, so as to ensure the need for calcium in the body.

Some people say that if you eat too much calcium, you won't grow taller, which has no scientific basis

1. Innate heredity.

The color of the hair varies depending on the type of pigment contained in the hair. There are three pigments in hair, which are eumelanin, red melanin, and melanin. The color of these three pigments is different.

Due to the different proportions of the above pigments contained in the hair, there will be different colors of hair.

2. Malnutrition.

Most of the main factors that cause yellow hair are the lack of good nutrition, so at this time, we should pay attention to the allocation of diet, eat more food in daily life, and reach a saturated and comprehensive level, only in this way can we improve the nutritional status of the body.

3. Acidic constitution.

The reason for the yellowish hair is basically related to the increase of acidic toxins in the blood, and of course, it is also related to overwork and overeating sweets and fatty foods.

4. There is a lack of copper in the body.

If there is a lack of tyrosinase containing copper, which is an important substance in the production of melanin, then if there is a lack of ketone in the body, then the activity of the enzyme will be reduced, and once it is reduced, it will not be conducive to the production of other substances, which will lead to yellowing of the hair.

5. Radioactivity.

If you have been engaged in some computer, radar and other work for a long time, then your hair will also appear yellowish.

There are several reasons:

1.Probably because of genetics. Some parents have yellow hair, and children are born with yellow hair.

2.It may be a lack of nutrients. Hair lacking certain trace elements will dry out and turn yellow. For example, iron anemia can lead to malnutrition in the hair; Copper deficiency can affect the metabolism of melanin, zinc deficiency can affect the growth and development of cells, and hair will naturally turn yellow.

3.In terms of the physiological characteristics of hair, every hair has a hair follicle at the root, and around it there are keratinocytes and pigment cells of hair, and once the function of these cells is disturbed or damaged, black hair will turn yellow.

4.Wash your hair too often or with alkaline soap.

5.People think it is related to eating food or fat. This is because these substances are prone to lactic acid or carbonic acid in the body. When there is too much acid, the hair gradually turns yellow.

6.Caused by certain diseases, such as systemic scleroderma and systemic lupus erythematosus, hair not only turns yellow, but also falls out profusely.

Some people's hair does not turn gray but gradually turns yellow, which is mainly due to mental tension, excessive fatigue and improper diet, such as eating sugar and too much fat, resulting in excessive lactic acid, glacial acetic acid, carbonic acid and other acidic substances produced in the metabolic process in the body. In response to this situation, the precautionary measures are as follows:

Have a regular life, pay attention to the combination of work and rest, and avoid mental tension and excessive fatigue.

Pay attention to a balanced diet, eat more iodine, calcium, and protein-rich foods, such as kelp, seaweed, fish, fresh milk, eggs, soy products, etc. You should also eat more foods that contain iron, as iron has an inhibitory effect on acidic foods. Pork liver, beef liver, onions, etc. are easy to cause too much acidity in the blood, so you should not eat more.
