What is the main component of nail anatomy?

The main component of nail anatomy is keratin. This fibrous protein forms the structural foundation of nails, providing strength and resilience. Keratin is synthesized in the nail matrix, where it plays a crucial role in the growth and overall health of nails. This protein is also a key element in other parts of the body, such as hair and the outer layer of skin, highlighting its significance in maintaining the integrity of various structures.

While collagen contributes to the overall structure and strength of the skin, it does not play a direct role in the composition of the nails themselves. Calcium is important for overall nail health and growth, but it is not the primary structural component. Biotin is known to support nail growth and health, but it is also not a constituent of nail anatomy, serving more as a supplement for promoting healthy nails rather than being a component of their structure.
