The free edge is white, translucent, or yellow in appearance as it no longer has the nail bed which contains blood vessels underneath to give the pink tone the nail plate often appears to have, due to the nail bed underneath. It is important to have a free edge as this ensures that all the nail bed is covered and therefore protected.

Learn how to safely file the free edge here. Care must be taken when shaping and removing length to not detach this hyponychium and cause discomfort. This can lead to the extended hyponychium, where the hyponychium can protrude over the finger pad up the back of the nail plate. The longer this grows, the further up the back of the nail plate the hyponychium can grow. When the nail plate extends beyond the hyponychium, this becomes the free edge. The nail continues to grow forwards in the shape and width of the nail bed. When they first become exposed from under the cuticle, the cells are soft and spongey and only harden and keratinise when exposed to the air. The cells originate in the matrix and move forward towards the fingertips. The underside of the finger is fleshy, and the nail covers the pad-like topside. As these nerve fibres are very sensitive and fragile, it is important to protect these. The fingertips contain a lot of sensory endings that allow us to distinguish touch, pain, and temperature. The function of the nail is to protect the outermost bone of the finger or toe, the fingertip, and the surrounding soft tissues from injuries. To understand the function of the free edge or nail tip, we must firstly understand how and why the nail grows.
