What is the cause of premature graying of hair?

Now my friends around me have always been troubled by a question: what is the reason why young people have white hair so early? In fact, what determines hair color is the amount of pigment particles in the hair, which is related to the development and growth of pigment cells in the hair root papilla. Generally speaking, the hair pigment cells of normal people begin to decline from the age of 35, but some people have white hair at the age of 20, which is called "premature graying". Below, I will talk about some detailed reasons causing 'premature graying'.

Juvenile graying, known as premature graying in Western medicine, is a graying disease in children and young people. Its cause is very complex. There are two major types, one is congenital premature graying of hair and the other is acquired premature graying of hair. Many acquired premature graying of hair occur along with certain diseases, while some are caused by excessive mental stress and malnutrition.

1. Mental factors.

Mental stress, sadness, anxiety, panic and fright are all causes of premature graying of hair. Modern medicine believes that negative mental factors can cause spasms in the blood vessels that supply nutrients to the hair, causing dysfunction in the melanin secretion function of the pigment cells in the hair papilla and hair bulb, affecting the formation and transport of melanin particles.

2. Suffering from chronic diseases.

Some people who suffer from autonomic dysfunction, hyperthyroidism, tuberculosis, typhoid fever, endocrine disorders, etc. may also have gray hair. This is because the disease destroys or interferes with the growth and development of the hair papilla and hair bulb pigment cells, causing them to lose the ability to secrete melanin and hindering the formation of melanin granules.

3. Nutritional imbalance.

The pigment particles in black hair contain elements such as copper, cobalt, and iron. If these elements are lacking, white hair often appears. also. Lack of protein, severe malnutrition, etc. can also cause gray hair.

4Genetic factors.

Juvenile graying of hair also has certain congenital factors, and similar situations may occur in parents or family bloodline.

Do you understand now? In fact, the most important point in preventing and treating juvenile gray hair is one's own psychological factors. If you have a few gray hairs, don't be too nervous. You need to maintain a good mood. You should also pay attention to a healthy diet, not be picky about food, and eat more nutritious grains, fruits and vegetables.
