6. Causes of white hair
1, age factor
When people get old, their physical function declines day by day. Although tyrosinase producing melanin will still appear, its activity is decreasing day by day, which leads to the decrease of melanin production to maintain black hair. In addition, as people get older, there will be fewer and fewer melanocytes in the body, and black hair will gradually turn gray.
2. Genetic factors
We often say that "young baldness" may be due to heredity that leads to gray hair at a young age. Because of the influence of genetic genes, it may lead to the congenital deficiency of some elements in the body or affect the absorption and utilization of some elements in the body, thus leading to long white hair. In addition, if it is a family hereditary disease, it may also lead to long white hair.
3. Malnutrition
People who suffer from long-term malnutrition are also prone to grow white hair, and maintaining normal black hair also requires nutritional supply. If the body lacks vitamins, minerals and other nutrients for a long time, the hair will turn white. Long-term malnutrition will also affect the normal secretion of melanin by melanocytes and lead to long white hair.
4, acidosis
Long-term preference for eating acidic foods, or eating sweets and other foods, may lead to acidosis in the body, but also lead to long white hair. In addition, long-term intake of excessive salt may also promote the growth of white hair.
5. Effects of diseases
If the body suffers from endocrine system diseases, pituitary diseases, vitiligo, albinism and other diseases, it may lead to long hoary head. In addition, it may be that the body suffers from chronic wasting diseases such as tuberculosis, which leads to abnormal absorption and consumption of nutrients in the body, and the hair tends to turn white.
6, depressed
As the saying goes, "I am a bald head", long-term depression and more depressed and nervous mood will affect the contraction of blood vessels in the head and the oxygen supply capacity of normal blood vessels. This will affect the normal absorption of nutrients and blood by hair roots, lead to the decline of the ability of hair roots to produce melanin, and eventually lead to long white hair.
