What is the technical term for a nail?

The technical term for a nail is "onyx." This term is derived from the Greek word for nail and is used in the anatomical and medical contexts to refer specifically to the hard protective covering that exists on the tips of fingers and toes. Understanding the term "onyx" is beneficial for barbers, particularly in services involving manicures or pedicures, as it is important for recognizing the structure and health of nails when providing grooming and maintenance services.

The other terms listed have distinct meanings in the context of nail anatomy. The cuticle refers to the layer of skin at the base of the nail, protecting the area from infection. The matrix is the tissue beneath the base of the nail from which the nail grows. Lamellae typically refer to thin sheets or layers and do not specify the nail itself. Each term plays a role in nail health and care, but "onyx" is the recognized term for the nail itself.
