During a manicure, how should the nails be filed?

Filing nails in one direction is important because it helps to prevent splitting and breaking of the nail. When a file is moved back and forth, it can create friction that weakens the nail structure, leading to potential damage. Filing in one direction promotes smoother edges and allows for better control over the shape of the nail.

This technique is especially useful for natural nails, which can be more susceptible to damage than artificial nails. Maintaining the integrity of the nail is essential to both the health of the client's nails and the overall appearance of the manicure. By filing in a single direction, the manicurist ensures that the nail tips remain strong and healthy while achieving a neat and polished look.
