What is the role of the nail matrix?

The role of the nail matrix is fundamental in nail health and growth. This structure, located beneath the base of the nail, is responsible for producing new nail cells. As these new cells are generated, they push older cells forward, which eventually harden and form the visible nail plate. This production is essential because it determines the thickness and overall health of the nails.

While protecting the nail bed is important, that function is performed primarily by the nail itself once it becomes visible. The nail matrix does not impart color to the nails; rather, the coloration is determined by the underlying tissues and any pigment present in the cells. Flexibility of the nails is also influenced by various factors including hydration and nail health, but it is not the direct role of the matrix. The primary focus of the matrix is the creation of new cells, which underlines the importance of this structure in nail growth and maintenance.
