MICROANATOMY

Detailed explanation-1: -Keratin is a protein that your body produces naturally, and it helps keep your hair, skin and nails healthy and strong. Your body produces keratin naturally, but keratin shampoos and conditioners that contain keratin hydrolysates may strengthen your hair and improve its appearance.

Detailed explanation-2: -Your nails are made from a protein known as keratin, unlike bones, which are made mostly of collagen. Keratin protects nails from damage by making them strong and resilient. Keratin forms the cells of your hair and skin, too. It also forms cells that are a key part of many glands and that line internal organs.

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: -It was found that nail contained epidermal and hair keratins. With 50 mM 2-mercaptoethanol, only epidermal type of keratins including skin differentiation specific-keratin could be extracted, whereas hair type of keratins required 200 mM 2-mercaptoethanol for extraction from nail.

Detailed explanation-5: -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.
