Where does nail growth originate?

Nail growth originates from the active tissue in the matrix, which is located under the base of the nail where the nail bed meets the skin. The matrix is responsible for producing new nail cells, which push older cells forward, causing the nail to grow. This process is crucial for the overall health and appearance of the nail. The matrix contains specialized cells that generate keratin, the protein that makes up the nail.

The other areas mentioned, such as inside the eponychium, the cuticle area, or under the free edge, do not play a direct role in the growth of the nail. Instead, they serve other functions, such as protection for the nail matrix and maintaining the health of the surrounding skin and nail structures. Understanding that the matrix is the core area for nail growth is essential for nail technology professionals, as it underlines the importance of maintaining the health of this tissue to ensure proper nail development.
