What part of the nail does the free edge form?

The free edge forms the distal nail plate, which is the part of the nail that extends beyond the fingertip. This area is crucial for nail aesthetics and functionality, as it protects the underlying sensitive tissues of the fingertip. The free edge is formed as the nail grows, and its health can indicate overall nail care and hygiene.

Understanding the anatomy of the nail is key for nail technicians, as each part has specific roles in nail growth and health. The proximal nail fold is the skin that overlaps the base of the nail, while the lateral nail folds are the skin that runs along the sides of the nail. The lunula, which is the crescent-shaped white area at the base of the nail, is also distinct from the free edge and relates more to the growth process than to the actual distal part of the nail. Recognizing these different components helps professionals provide better care and services for clients.
