What is the natural nail commonly referred to as?

The natural nail is commonly referred to as onyx. This term is derived from the Greek word "onyx," meaning claw or fingernail. It specifically describes the hard, protective keratin structure that makes up the visible part of the nail, which extends from the nail bed to the free edge. Understanding this terminology is important for nail technicians, as it helps them communicate effectively about nail anatomy and the importance of nail care.

While keratin is the fibrous protein that comprises the nail, it is not the name of the nail itself. The cuticle refers to the thin layer of skin that overlaps the base of the nail, serving as a protective barrier, rather than the nail structure. The nail matrix is located beneath the base of the nail and is where nail growth occurs, but it is not what the natural nail is called. Thus, onyx accurately identifies the natural nail and is an essential term in the field of nail technology.
