Nails are made of dead cells that contain keratin, the protein found in the outer layer of skin. Nails grow by being pushed out of a pit in the skin called the nail-bed, which lies horizontal to the skin. As the nail grows it slides along the surface of the nail-bed to the fingertip. Most of the nail is pink, because the blood vessels underneath it shows through.
