Hair grows like grass and trees, although it seems to be silent, every subtle movement is actually growing silently. Want to know how fast your hair grows? Let me introduce you to one or two.
According to scientific research, human hair grows at a relatively slow rate. It takes them about three days to grow about 1 millimeter, and about 1 centimeter in a month. That is, for a person's hair, the length can be changed once every six months.
When we cut or comb out hair, have you ever observed the tops of those hairs? They are usually flattened and round, shaped like an onion, which is the root of the hair, and their apparent process embodies the wonderful journey of nature. This root is similar to the root system of a plant and is responsible for absorbing nutrients and providing them to the hair strands, allowing the hair to continue to grow.
Hair growth is nourished by the blood, and a large number of capillaries flowing through the hair roots carry a rich source of nutrients. It is because of the moisture of the blood that the hair has enough strength to continue to extend until it reaches the desired length. But, let's not forget, everything has an end, and hair is no exception. A healthy hair can survive for 3 to 5 years before falling out on its own. At this time, a new hair will take root in the place of the old hair and start a new cycle.
All in all, beautiful black hair is a precious treasure given to us by nature. In addition to normal care, knowing the pattern of hair growth can help us better protect this beauty and health. Hopefully, the above tips about hair will help you.
