What type of nail disorder is often treated by buffing the nail surface?

Buffing the nail surface is particularly effective for treating corrugations, which are ridges or furrows that can appear on the nail. These irregularities in the nail's surface can be caused by various factors, such as nutritional deficiencies, trauma, or underlying health conditions. Buffing smooths out the surface imperfections, making the nails appear healthier and more polished.

This treatment is not as suitable for other conditions. While brittle nails might benefit from hydration and strengthening treatments, buffing does not address the underlying causes such as moisture loss or damage. Hangnails are excess skin near the nail and require trimming rather than buffing. Discolored nails might indicate issues such as infections or systemic problems, and buffing does not resolve the discoloration itself. Therefore, buffing is most appropriate and effective for treating corrugations specifically.
