Have you ever heard the saying “If you pull out one grey hair, ten will grow back?” How can you avoid having grey hair at a young age?

When I was in high school, I got my first white hair in my life. Just as I was sharpening my knife and preparing to pull it out in front of the mirror, my grandmother stopped me in a hurry and said, "Don't pull out white hair. If you pull out one, ten will grow!" Hearing this conclusion, I was so scared that I quickly let go of the white hair in my hand. Today, many years later, when I saw my white hair in the mirror again, I decided to explain to everyone why I have white hair at such a young age. Is it true that the more you pull out the white hair, the more it will grow?

Why do white hair grow? Why do people grow white hair? What is the difference between white hair and black hair? In fact, the color of hair is determined during embryonic development. Melanoblasts in the neural crest are implanted in the hair follicle bulb, also known as hair follicle melanocytes.

The growth of hair first depends on the hair matrix cells in the hair follicles. The hair matrix cells divide continuously, so the hair keeps growing. The hair follicle melanocytes play a vital role in the color of hair. The hair follicle melanocytes continuously form melanin, and the new hair is constantly "dyed", so our hair has color. As we age, the function of the hair follicle melanocytes gradually declines, and the hair without the "dye" gradually turns white, which is why we have more and more white hair as we age.

Will pulling out white hair make more hair grow? Will pulling out one really make ten grow? What happens when you pull out white hair? Will black hair grow out? Will pulling out one make ten grow? Will the more you pull out, the more hair you get?

The correct answer is: If you pull out a white hair, no black hair will grow, nor will ten white hairs grow, but instead another white hair will grow.

After the white hair is plucked, as long as the hair follicles function normally, new hair will still grow. At this time, because the melanocytes in the hair follicles still cannot secrete enough melanin, they cannot "dye" the new hair, so the hair that grows is still white hair. When the white hair is repeatedly plucked, this behavior is likely to damage the hair follicles. Once the hair follicles are damaged, no more hair will grow. Therefore, plucking one white hair will not turn into ten, but will remain one or zero.

What habits can prevent the occurrence of gray hair? ●Regular daily routine

A regular lifestyle can effectively delay the generation of gray hair. Staying up late is the "natural enemy" of black hair. Sufficient and high-quality sleep can ensure the normal metabolism of the human body's hair, while staying up late for a long time will lead to a decrease in the secretion function of the melanocytes of the hair follicles, and even cause problems with the hair follicles. Therefore, many people who stay up late for a long time not only have a lot of gray hair but also often have a "touching" hairline.

●Relax your mind and avoid long-term mental stress

Many people have heard the story of "Wu Zixu's hair turned white overnight". Although the authenticity of the story is worth studying, mental factors such as tension and anxiety can indeed accelerate the formation of gray hair. Although people have not yet clarified the mechanism, the current mainstream view is that mental stress can cause melanocyte stem cells to migrate, thus leading to the formation of gray hair.

● Eat a healthy diet to prevent hair malnutrition

When the human body is in a state of malnutrition for a long time, our hair will also produce gray hair due to malnutrition. Melanocytes use tyrosine in the body to convert melanin. When tyrosine is deficient, the production of melanin will be restricted, thereby increasing the production of gray hair.

Summary: Pulling out one white hair will not make ten grow, but one white hair will grow if you pull it out. When you pull out the hair follicles repeatedly, they will be damaged and no hair will grow again.
