What is the primary function of nail folds?

The primary function of nail folds is to protect the nail matrix, which is the area where the nail grows from. Nail folds are the layers of skin located on either side of the nail, and they serve as a protective barrier that helps keep the nail matrix healthy and free from injury or infection. Additionally, by providing support to the growing nail, the nail folds contribute to the overall strength and structure of the nail as it develops.

Understanding the protective role of nail folds is crucial for nail technicians, as maintaining the health of the matrix can influence the appearance and integrity of the nails. While other options mention functions related to aesthetics or activities associated with nails, they do not capture the essential biological role that nail folds play in supporting nail growth and protection.
