keratin, fibrous structural protein of hair, nails, horn, hoofs, wool, feathers, and of the epithelial cells in the outermost layers of the skin. Keratin serves important structural and protective functions, particularly in the epithelium.

In short, where is keratin found and how is it formed?
A type of protein found on epithelial cells, which line the inside and outside surfaces of the body. Keratins help form the tissues of the hair, nails, and the outer layer of the skin. They are also found on cells in the lining of organs, glands, and other parts of the body.
Still, where does keratin come from? Keratin is a protective protein, less prone to scratching or tearing than other types of cells your body produces. Keratin can be derived from the feathers, horns, and wool of different animals and used as an ingredient in hair cosmetics.
Furthermore there, how is keratin formed in the body?
Hair grows by forming new cells at the base of the root. These cells multiply to form a rod of tissue in the skin. The rods of cells move upward through the skin as new cells form beneath them. As they move up, they're cut off from their supply of nourishment and start to form a hard protein called keratin.
Can we digest keratin?
No, they cannot survive on such a diet. Nails and hair are made of keratin. Keratin is very much not digestible: Keratin is highly resistant to digestive acids if it is ingested (Trichophagia).

While it is true that all three contain keratin, the amount of keratin contained within the enamel of our teeth is significantly lower than the keratin in our nails and hair. Our teeth are not bones. Bones have a composition of collagen fibers and bone material which forms small crystals.
Keratin is a fibrous structural protein found in animal cells and used to form specialized tissues. Specifically, the proteins are only produced by chordates (vertebrates, Amphioxus, and urochordates), which includes mammals, birds, fish, reptiles, and amphibians.
Keratin is an important protein in the epidermis. Keratin has two main functions: to adhere cells to each other and to form a protective layer on the outside of the skin. In epithelial cells, keratin proteins inside the cell attach to proteins called desmosomes on the surface.

In particular, keratin helps make the cells in hair, skin, and nails stronger and more resilient and helps reduce damage to the tissues from friction. Keratins also help: regulate the size of cells. allow cells to move, grow, and divide.
The keratinocytes of the skin are unique in being not only the primary source of vitamin D for the body, but in possessing both the enzymatic machinery to metabolize the vitamin D produced to active metabolites (in particular 1,25(OH)2D) and the vitamin D receptor (VDR) that enables the keratinocytes to respond to the ...

Hair, and also feathers, are ectodermal structures containing keratin that probably evolved from keratinised epidermal scales in a common ancestor of mammals and reptiles. Fish scales on the other hand do not contain keratin.
