Your hair is one of the most prominent manifestations of your beauty, and because of its importance, we will cover many topics for you so that you can learn more information about it and how to care for it.
Hair and skin layers
Your hair grows from your skin, and if you look at your skin, it is composed of: three main layers:
The outer layer is called the “epidermis layer” and its thickness is on average 0.2 mm.
The middle layer is called the “dermis layer,” and it is the thickest of the three layers. Its thickness reaches 2 mm. This layer contains:
* Blood vessels that nourish the skin and hair.
* Lymphatic vessels
* Nerves.
The inner layer is called the “subdermis layer.” It consists of a group of fat cells, and therefore it is sometimes called the adipose layer.
• There are what are known as skin appendages, which are the sebaceous glands, the hair follicle that contains the lower part of the hair, the sweat glands, and the nails. These appendages appear clearly in the sebum.
Hair formation
Poetry consists of two parts:
• A part that we see with our eyes above the surface of the skin is called the “leg.”
• A part that we cannot see, implanted under the skin, is called the “root.”
There is a deep part of the hair root that resembles an onion and is therefore called the hair follicle.
If we want to see the hair follicle with our own eyes, we have to forcefully remove a hair from the head, and we see a concave white part at the back of the hair. This is the hair follicle.
What is the importance of this follicle?
The follicle, as we mentioned, is the lower part of the hair under the surface of the skin. It is the only living part of the hair and is also responsible for the formation of the hair parts through distinct cells.
The follicle is connected to the dermis layer of the skin through a place called the nipple, and through this nipple and the blood capillaries that reach it, the hair receives its nourishment.
What is a hair follicle?
It is a modified part of the skin layers that resembles a bursa, hence the name.
This follicle surrounds the deep part of the hair, and at the base of this follicle there is the papillae, which is a group of active, rapidly dividing cells that develop and mutate into cells and corneas, each cell of which represents the basic building block that forms the hair.
This nipple is the one that transports nourishment from the blood to the hair root (the hair follicle).
