Detailed explanation-1: -Keratin is a protein that helps form hair, nails and your skin’s outer layer (epidermis). It helps support your skin, heal wounds and keep your nails and hair healthy. There are 54 kinds of keratin in your body.

Detailed explanation-2: -Fingernails and toenails are made of a tough protective protein called alpha-keratin, which is a polymer.

Detailed explanation-3: -Our nails and hair are made up of a protein known as keratin. Keratin belongs to a group of fibrous structural proteins that are known as scleroproteins. The hair grows in a hair follicle, and nails grow from the matrix i.e., the base of the nail bed.

Detailed explanation-4: -Keratin, like all proteins, is made up of amino acids. Each protein contains its specific order of amino acids, much like each person contains its string of deoxyribonucleic acid (DNA). While keratin can also be found in internal organs and glands, they are primarily found in epithelial cells.
