What is the function of the matrix in nail growth?

The matrix plays a crucial role in nail growth as it is responsible for producing new nail cells. Located beneath the base of the nail, the matrix is where the nail plate originates and is made up of rapidly dividing keratinocytes. As these cells multiply and mature, they harden and are pushed out to form the visible part of the nail. This continual production of new cells is vital for nail elongation and health. If the matrix is damaged, it can affect the appearance and growth of the nail, potentially leading to issues like deformations or slow growth. This foundational function underscores the importance of the matrix in maintaining healthy nail growth and structure.
