What is the role of a cuticle in nail health?

The cuticle plays a crucial role in maintaining nail health by acting as a protective barrier between the nail’s surface and the surrounding skin. It helps prevent bacteria and other pathogens from entering the area, which can lead to infections. Additionally, the cuticle aids in keeping the nail bed hydrated, promoting overall nail growth and strength.

The other options focus on attributes that the cuticle does not provide. For instance, the cuticle does not contribute to the length of the nail, enhance color, or serve as a base for nail designs. Its primary function is protective, making it essential for maintaining healthy, well-nourished nails.
