Why do nail technicians shape or file the nail before soaking it in water?

The practice of shaping or filing nails before soaking is primarily rooted in the understanding that filing dry nails provides better control and precision over the filing process. When nails are dry, they are more rigid, allowing the technician to effectively shape the nail without the risk of the nail bending or tearing, which can occur when nails are soaked and subsequently softened.

Furthermore, filing dry nails minimizes the chance of causing damage to the nail structure itself. Wet nails may become more pliable and could lead to uneven edges or breakage, as they can bend under pressure. By shaping the nails first, the technician can ensure a clean and accurate shape that enhances the overall appearance and prepares the nails for any additional treatments such as soaking or polishing.

The other options do not accurately reflect the best practices for nail care and filing. For instance, while soaking nails may be a common pre-treatment step for other procedures like manicure preparation, it is not necessary before filing as it can compromise the effectiveness of the shaping process.
