What are nails composed of?

Nails are primarily composed of keratin, which is a type of protein that is also found in hair and the outer layer of skin. Keratin provides strength and resilience to nails, allowing them to protect the tips of fingers and toes. The structure of the nail consists of hard, dead cells that contain this fibrous protein, making it tough and durable. Understanding the composition of nails is crucial for nail technicians, as it influences the types of products and services used in manicure and pedicure treatments. While collagen and other proteins play important roles in the body, they do not compose nails specifically. Calcium is also important for overall nail health, but it is not a structural component of nails themselves.
