What are fingernails and toenails made of?
user
Fingernails and toenails are made of a hardened protein called keratin. This protein is found in our skin and hair. It is also the same stuff that makes claws, hooves, and horns in animals!
Our nails are tough plates of hardened cells that, while dead, are constantly growing. The formation of a nail begins at the nail root, a part of your fingertip that lies under your skin. Here the cells that form the nail plate gradually die, harden, and push out from under the skin.
