What is the free edge of the nail?

The free edge of the nail refers to the portion that extends beyond the fingertip. This area is not attached to the skin and serves as the part of the nail that is visible and often cut or shaped during a manicure. It is important because it is the part that may be prone to breakage or chipping. Understanding the free edge is crucial in manicure practice, as it helps in providing proper nail care, ensuring that the nails are maintained in a healthy state while achieving the desired aesthetic look.

The other options describe different components of the nail structure or skin around the nail but do not accurately capture the definition of the free edge. The skin overlapping the sides refers to the nail folds, while the protective shield of the nail and the layer of skin mentioned refer to the nail plate and cuticle, respectively. Recognizing these distinctions is essential for any nail care professional.
