Are you sensitive to hair loss but indifferent to the mechanism of hair growth? To understand the mechanism of hair growth, it is first necessary to understand the structure of hair.
Hair is the result of skin changes.
Where do you first think of when you hear the word “skin?”
Arms? Legs? If you think of “hair,” you are a “connoisseur. If you can intuitively guess “hair,” you are a “connoisseur.
Hair is a keratinous appendage formed by the differentiation of keratin of the skin, and its original purpose is to act as a sensory organ, protect the scalp, and keep the scalp warm. However, hair currently seems to have the highest “aesthetic significance.
Hair is divided into two main parts: the first is the part that emerges from the scalp and is called the “hair shaft. This is the part that we usually use for hairdressing, perms, and coloring. The other part is called the “hair root,” which is located under the scalp. It is in the root of the hair shaft that the hair grows.
How hair grows
At the base of the hair root area, there is a round, onion-shaped part called the “hair bulb. This is where hair is produced.
(1) The “hair papilla” inside the hair bulb converts nutrients from the blood into the necessary form and supplies them to the “hair matrix cells.
(2) The nourished hair matrix repeats division
(3) The hair matrix cells that have proliferated through division are pushed up toward the scalp
(4) In the process of pushing up, the cells lose water and become keratinized to form hair.
This is the mechanism of hair growth.
Here is a piece of trivia. Plants and hair grow vertically in the same way, so you may have an image of them being identical, but there is a big difference. Plants grow from their tips, whereas hair grows from the root. In other words, the papilla plays a very important role for hair.
