Explanation:
Detailed explanation-1: -Keratins are a group of tough, fibrous proteins that form the structural framework of cells called keratinocytes that make up the skin, hair, and nails. Keratin 1 is produced in keratinocytes in the outer layer of the skin (the epidermis), including the skin on the palms of the hands and soles of the feet.
Detailed explanation-2: -Hair is composed of 95% keratin, a fibrous and helical protein (in the shape of a helix), which is part of the composition of the skin and of all the phanera (hair, nails, etc.). Synthesized by keratinocytes, keratin is insoluble in water, thus ensuring waterproofing and protection for hair.
