What is the role of a cuticle in nail health?

The cuticle plays a crucial role in maintaining nail health primarily by protecting the nail matrix, which is the tissue under the base of the nail where new nail growth occurs. It acts as a barrier, preventing pathogens and microorganisms from entering the nail bed and matrix, thereby significantly reducing the risk of infections that could affect nail growth and overall nail health.

While cuticles can help with moisture retention and contribute to the overall appearance of nails, their main function is to serve as a protective barrier. The other options, such as enhancing nail growth or improving nail color, are not functions of the cuticle itself. The cuticle’s protective feature is what ensures that the nails remain healthy and can grow properly without the risk of infections that could arise from exposure to harmful elements.
