How can improper filing affect the nails?

Improper filing can lead to splitting and chipping of the nails because using the wrong technique or tools can cause trauma to the nail's structure. When nails are filed incorrectly—such as using a rough file, filing in a back-and-forth motion, or filing too aggressively—they can become weakened. This damage can create frayed edges or cracks in the nail, making them more susceptible to splitting and chipping during everyday activities. Maintaining proper filing technique with the appropriate tools is essential for promoting nail integrity and health, ultimately preventing these types of damage.

The other options do not reflect the consequences of improper filing. For example, while filing can certainly be done to enhance nail health when done correctly, improper filing does the opposite. Similarly, while proper nail care can help strengthen nails, the improper technique can lead to weaknesses rather than benefits. As for increasing nail growth speed, this is generally influenced by a range of factors including health, nutrition, and genetics, rather than the filing method used.
