Which part of the nail extends over the tip of the finger?

The free edge is the part of the nail that extends beyond the fingertip. It is visible and can often be seen protruding out from the end of the finger, giving the nail its length and shape. This area is the portion of the nail that is not attached to the nail bed and can be trimmed or shaped according to personal preference or grooming practices.

The nail plate refers to the hard, protective layer of the nail that sits on top of the nail bed, while the lunula is the pale crescent-shaped area at the base of the nail plate. The hyponychium is the area of skin located beneath the free edge of the nail and serves as a protective barrier. Understanding the structures of the nail is important in cosmetology as it enhances the ability to provide proper nail care and apply nail techniques effectively.
