long white hairThe main reasons for long white hair were as follows:
1. ** Biological factors **: As one grows older, the amount of dark matter in the human body will gradually decrease, causing the hair to turn white.
2. ** Genetic factors **: If parents or grandparents have white hair early, the offspring may also have white hair earlier. Genetic factors can cause premature death of the mitochondria.
3. ** Malnutrition **: A lack of nutrients such as vitamins B12, folate, B vitamins, Tyrosinase, iron, zincate, and iodinate, or a lack of Biotin can cause hair loss. At the same time, it may also affect the formation of dark matter, causing hair to turn white prematurely.
4. ** Disease factors **: Some diseases can cause hair to turn white, such as hypothyreosis, copper metabolism disorder, vitigo, white hair, auto-immune pernicious leukemia, albinism, mottled disease, and pheketonuria.
5. [Mental stress: Long-term high-pressure will increase the secretion of adrenaline and suppress the formation of dark matter.] When mental stress was high, the blood vessels in the head contracted, the blood supply to the hair decreased, and the amount of synthetic obin decreased accordingly. Moreover, when the body was under great stress, the secretion of adrenaline and norepinephrin would consume the body's receptor, which would lead to early white hair.
6. ** Smoking **: Long-term smoking will cause the body to produce too much oxygen and oxygen free radical, which will accumulate in the hair scalp and damage the cells, causing the number of cells to decrease. The hair will turn white because it cannot synthesize more black.
7. ** Poor blood circulation in the scalp **: This will affect the nutrient supply of the hair, which will lead to the appearance of white hair.
8. [Kidney Deficiency]: Weakened blood and kidney qi may also lead to more white hair.
In order to prevent long hair, you can start from the following aspects:
1. ** Eat a balanced diet **: Eat enough vitamins and minerals, eat more foods rich in vitamins E, A, and C, such as black dates, persimmons, shiitake mushrooms, and other fruits and vegetables; supplement more foods containing aluminum, such as beef liver, soybeans, seaweed, and so on. You can often eat black beans, black sesame seeds, and other foods.
2. ** Pressure adjustment **: Reasonably adjust the stress of work and life to avoid excessive fatigue.
3. ** Scalp Massage **: Regular scalp massage to promote hair growth.
4. ** Regular Haircut **: Reduce the breaking of hair ends and slow down the speed of hair turning white.
5. ** avoid using chemicals **: avoid using chemicals such as hair dye to reduce damage to hair.
