What is the term for the natural nail's regenerative layer?

The term for the natural nail's regenerative layer is the nail matrix. This is the tissue located under the base of the nail, beneath the cuticle, that is pivotal in the nail growth process. The matrix is where new nail cells are produced, and as these cells multiply, they push older cells forward, creating a hard nail plate that eventually extends beyond the fingertip. The health and condition of the nail matrix significantly influence the appearance and growth rate of the nails. Understanding the role of the nail matrix is essential for nail technicians, as it can impact various treatments and nail care practices.
