What sound does hard nail enhancements make when lightly tapped with a brush handle?

When hard nail enhancements are lightly tapped with a brush handle, they produce a clicking sound. This sound is indicative of the density and durability of the enhancement material. A clicking sound typically occurs because the surface of the enhancement is solid, and the tap creates a vibration that resonates through the material.

This characteristic sound is useful for nail technicians to assess the hardness and quality of the enhancement. If the enhancements were too soft or improperly cured, they might produce a different sound, such as a thump or no sound at all, indicating potential issues with the treatment. Therefore, the clicking sound serves as a practical indicator of correct application and the expected performance of the hard nail enhancements.
