Toenails are composed of a protein called keratin, which is also found in hair and skin. The keratin in toenails is densely packed and arranged in layers, providing strength and rigidity. Additionally, the nail bed underneath the toenail provides a supportive structure, contributing to its thickness and durability. Proper nutrition and overall health also play a role in maintaining strong and thick toenails.
