Why do we grow white hair?
1. Age
As we age, the hair follicles are worn out and produce a lot of hydrogen peroxide, which is the main reason for the whitening of hair. This is because hydrogen peroxide hinders the normal synthesis of melanin, the natural pigment of hair.
2. Psychological factors
When people are in a state of anxiety, tension, and depression for a long time, the blood circulation and internal environment of the brain will be damaged to a certain extent, causing headaches, dizziness, white hair, etc.
3. Poor nutritional status
If the diet lacks copper, cobalt, iron protein, vegetable oil, vitamin B1, vitamin B2, vitamin B6, etc. for a long time, it will cause the hair to turn from black to white.
4. Certain diseases
Some patients have been affected by physiological chronic wasting diseases such as hyperthyroidism, tuberculosis, typhoid fever, pernicious anemia, etc. for a long time, which can also cause a small amount of white hair. However, according to experts, this pathological white hair can turn black. In addition to working hard to treat the disease, you should also pay more attention to relieving stress and develop correct living and eating habits.
5. Incorrect living habits
In addition to some physiological and psychological reasons, unhealthy living habits can also lead to the growth of gray hair. If you often go to bed without drying your hair, gray hair will also appear easily. This is because the hair will be in a "cold" state if it is not dried. Chronic wasting diseases similar to "typhoid fever" will stop the growth and development of hair bulb pigment cells, making it unable to lose the ability to secrete melanin, thereby hindering the formation of melanin particles.
6. Inheritance
Gray hair is hereditary, just like some people are born with the tendency to lose their hair into "Mediterranean" hair. People who grow gray hair earlier often have a family history, which is autosomal dominant inheritance. If your family members have grown gray hair at a young age, and the number is also large, then you are likely to grow gray hair earlier.
