Which technique helps prevent damage to the nail bed during filing?

Filing in one direction only is a technique that helps prevent damage to the nail bed. This method promotes smoother edges and reduces the risk of splitting or tearing the nail, which can occur when filing aggressively or in multiple directions. When a nail technician files in a straight line without the back-and-forth motion, it minimizes friction on the nail bed and promotes healthier nail growth.

Additionally, filing in one direction helps maintain the integrity of the keratin layers that make up the nail. This approach encourages the nail to maintain its strength and reduces the likelihood of damage, contributing to overall nail health and appearance. Therefore, employing this technique is crucial for maintaining the nails' condition, particularly in a professional nail care setting.
