What is a common effect of excessive filing of the natural nail?

Excessive filing of the natural nail can lead to thinning and weakening of the nail. This occurs because the outer layer of the nail, known as the nail plate, is composed of layers of keratin, and excessive filing removes this protective barrier. As the nail plate becomes thinner, it loses its structural integrity and resilience, making it more prone to breaking, splitting, or peeling. Healthy nail maintenance requires a balance; while gentle filing can smooth the nail, overdoing it can compromise its strength. Proper techniques and equipment should always be used during manicuring to maintain the health of the natural nail.
