Which implement is not typically used for caring for nails?

The hairbrush is not typically used for caring for nails because it serves a different purpose, primarily related to grooming hair rather than nails. In manicure and nail care, tools are specifically designed to address the condition and appearance of nails, such as cutting, shaping, and maintaining the health of both nails and the surrounding skin.

Nail nippers are used to trim excess nail or hangnails, tweezers can assist in picking up small items or removing debris from around the nails, and a fingerbowl is used to soak fingers to soften the nails and cuticles for easier care. A hairbrush, however, is intended solely for hair management and has no relevance or functionality in nail care routines. This distinction clarifies why the hairbrush is the correct answer as the implement not typically associated with nail care.
