Why does human hair grow continuously?

Not much is known about this issue at the moment.

In addition to the palms and plantar feet, hair grows on the surface of the human body.

Human hair can be divided into soft hair and hard hair according to the difference in thickness, softness and hardness.

Soft hairs, commonly known as hair hairs, are fine and soft and light-colored, covering the surface of **;

Bristles are coarse and stiff and grow on certain parts of the body, such as hair.

For adults, these two types of hair can be expanded into multiple types of hair, such as eyebrows, eyelashes, armpit hair, and beards, under the control of complex hormonal mechanisms. Whether it's smooth hair or tiny toe hair, it grows at a rate of 1 1 5 cm per month, and the hair stops growing for a very short time before it is about to fall out. Hairs on different parts of the body have different lifespans, which determines their limit length.

For example, leg hair can continue to grow for about 2 months and armpit hair for up to 6 months, but hair can grow for 6 years or more.

Long ago, our ancestors, like other mammals, were covered in hair. Later, due to the continuous evolution of human beings, the hair on the body gradually became thinner and shorter, and finally became the hair on our body now. However, because the brain contains the most important organ of our body, the brain, and hair has a good protective effect on the brain, it is maintained and preserved.

It has been suggested that this has something to do with genetics. It is believed that in the process of human evolution, the genes in the hair have been mutated to continue to grow. However, this hypothesis has not yet been fully scientifically confirmed.

In the process of human evolution, body hair was originally used for warmth, and after evolution, some body hair, such as hair and eyebrows, was retained, but these were only used for decoration. There is no practical use. As for hair, why it grows, of course, is metabolism.
