What is the primary function of the nail matrix?

The primary function of the nail matrix is to influence the nail's shape, size, and growth rate. The nail matrix is located beneath the base of the nail, within the nail fold, and is the growth area from which the nail plate develops. It contains specialized cells that produce keratin, the protein that forms nails, and as these cells multiply and push older cells forward, a new nail is formed. The health and activity of the matrix directly impact the nail's overall characteristics such as thickness, length, and curvature. Therefore, understanding the role of the nail matrix is essential for nail health and care, as any damage to this area can affect nail growth negatively.
