Why is it crucial to avoid overfiling nails?

Avoiding overfiling nails is crucial primarily because it can weaken the nail structure. When nails are overfiled, the layers that make up the nail plate can become compromised, leading to thinning and increased brittleness. This weakening can result in nails that are more susceptible to breakage or splitting, negatively impacting their health and appearance.

Maintaining the integrity of the nail structure is essential for healthy nail growth and overall nail strength. If the nails are consistently overfiled, this can lead to long-term damage, making recovery difficult without proper care and time. Healthy nails not only look better but also serve their protective role effectively, so it's important to be judicious about filing to maintain their strength and resilience.

Other aspects such as nail polish chipping, enhancing growth, or improving aesthetics could be secondary effects of nail condition but do not address the foundational issue of nail integrity and strength that is affected by overfiling.
