PSI Texas State Board Nail Tech Practice Exam 2025 – Complete Test Prep

Question: 1 / 400

Which type of nail file is best for natural nails?

A coarse-grit file

A fine-grit file

A fine-grit file is the most suitable choice for natural nails. This type of file has a smooth surface that gently shapes and refines the edges of the nail without causing damage or splitting. Using a fine-grit file ensures that the nails remain healthy while achieving a polished appearance, which is essential for maintaining the integrity of natural nails.

Coarse-grit files, while effective for filing artificial nails or shortening thick, tough nails, can be too harsh for natural nails, leading to rough edges or injury. Metal files, although durable, can also be excessive for natural nails and may cause splitting if used improperly. An emery board, though gentle like a fine-grit file, may not offer the same level of control and precision. Thus, the fine-grit file stands out as the ideal choice for natural nail care.
