What is the role of the nail cuticle?

The role of the nail cuticle is primarily to protect the nail matrix. The cuticle is a layer of clear skin located along the bottom edge of the nail. It acts as a barrier to prevent pathogens and foreign substances from entering the matrix, which is the area responsible for nail growth. By safeguarding the matrix, the cuticle helps maintain the health of the nail and supports its overall integrity and appearance. This protective function is crucial, as any damage or infection at the matrix can lead to nail deformities or growth issues. The other aspects, such as enhancing growth or providing color, are not functions associated with the cuticle.
