What is the reason for more and more white hair? Age-related inheritance is the most common reason

Many people will find that they have more and more white hair on their heads, and they will become very nervous. In fact, being nervous and overly worried will make more white hair. Gray hair is caused by many factors such as age, heredity, malnutrition, physical illness, etc., which require symptomatic treatment.

1. Age factor

As people age, their body functions decline. Although the tyrosinase that produces melanin still appears, its activity becomes increasingly low, resulting in a decrease in the production of melanin that keeps hair black. In addition, as people get older, the melanocytes in the body will gradually decrease, the melanin particles will gradually decrease, and the black hair will slowly turn gray.

2. Genetic factors

We often say "premature graying of hair", which may be caused by genetics, causing gray hair at a young age. Due to the influence of genetic genes, the body may be congenitally lacking in certain elements or its absorption and utilization of certain elements may be affected, leading to the growth of gray hair. In addition, if there is a hereditary disease in the family, it may also cause gray hair.

3. Malnutrition

People who suffer from long-term malnutrition are also prone to gray hair, and hair also needs nutrition to maintain its normal black color. If the body lacks vitamins, minerals and other nutrients for a long time, the hair will turn gray. Long-term malnutrition will also affect the normal secretion of melanin by melanocytes and cause gray hair.

4. Acidosis

Long-term preference for acidic foods, or a preference for sweets and other foods, may cause the body to be in a state of acidosis, which can also lead to gray hair. In addition, if you consume excessive salt for a long time, it may also promote the growth of white hair.

5. Physical illness

If you suffer from endocrine system diseases, pituitary diseases, vitiligo, albinism and other diseases, you may develop gray hair. In addition, the body may suffer from chronic wasting diseases such as tuberculosis, which leads to abnormal absorption and consumption of nutrients by the body, and the hair is prone to turning gray.

6. Depressed mood

As the saying goes, "worry can turn your hair gray." Long-term depression and a suppressed and nervous mood will cause the blood vessels in the head to contract, affecting the normal ability of the blood vessels in the head to supply blood and oxygen. This will affect the hair roots' normal absorption of nutrients and blood, leading to a decrease in the hair roots' ability to produce melanin, and ultimately causing the growth of gray hair.
