What tissue does hair belong to

Hair is mainly composed of protein. We know that if we burn a hair with a lighter, we will smell a smell of burning meat. This also shows that hair is protein tissue, which is mainly divided into three structures, namely the epidermis, cortex and medulla. From the chemical properties point of view, 97% of hair is protein, a kind of keratin, and the main component of these keratin is amino acids.

What tissue does hair belong to?

1. The structure of hair

1. Epidermis: It is composed of thin transparent bodies in the shape of fish scales. It is the protective layer of hair and also the outermost layer of hair. It is composed of overlapping keratin scales, which are connected by a substance similar to tin oxide.

2. Cortical layer: It is composed of spiral protein fibers and contains melanin particles inside.

3. Medullary layer: It is composed of vacuum-like spongy bodies arranged in an orderly manner. (Not present in fine hair)

2. Four Keys

1. Hydrogen bond: broken by water and reorganized by high temperature

2. Salt bond: determines the acid-base balance of hair

3. Disulfide bond: the hardest chain bond, which can be cut first and then reassembled

4. Amino bond: does not exist in fine hair

Chemical properties

1. The main component of hair is keratin, accounting for about 97%. Keratin is composed of amino acids.

2. Oriental hair is characterized by being thick, black, hard and heavy. Because it contains larger and more carbon and hydrogen particles, its color is dark. The characteristics of Western people's hair are soft and fine, and because it contains less carbon and hydrogen, its color is lighter.

3. The keratin protein that makes up the hair cuticle is composed of 20 kinds of amino acids arranged longitudinally.

4. Structure of hair: Each hair is composed of epidermal scale layer, cortex layer and medulla layer. The epidermal scale layer is the outermost layer of the hair and is usually composed of 2 to 4 layers of scales. The cuticle is usually translucent or colorless, so it allows the natural hair color to show through; the cortex accounts for 80% of the hair, where natural pigments are deposited, and the natural hair color is due to it; the medulla is located in the center of the head and is composed of many small bubbles.
