When performing a manicure, why is it recommended to file nails after clipping?

Filing nails after clipping is recommended primarily to shape and smooth rough edges. When nails are clipped, it can leave sharp or jagged edges that may not only be visually unappealing but also uncomfortable or even painful. Filing helps to refine the edges, creating a smooth and polished finish that enhances the overall appearance of the manicure. This step is crucial in achieving a professional look and ensuring client comfort since rough edges can snag on clothing or cause injury.

Although ensuring nails are even is a benefit of filing, the primary focus is on shaping and smoothing. The other options, such as making nails dye better or preventing contamination, do not directly relate to the purpose of filing after clipping. Therefore, the best answer centers on the importance of preparing the nail surface aesthetically and safely.
