What is a common misconception about nail care?

A common misconception about nail care is that nail polish strengthens nails. While many people apply nail polish to improve the appearance of their nails, it can actually have the opposite effect by causing dryness and brittleness. Nail polish contains various chemicals, and frequent application and removal can strip moisture from the nail plate, leading to weakness over time.

Additionally, when nails are kept coated for extended periods without proper care and hydration, they may become more susceptible to damage. This understanding is crucial for anyone looking to maintain healthy nails, as it's important to balance cosmetic use with nourishing and hydrating treatments. Therefore, while nail polish may temporarily enhance the look of nails, it does not contribute to their overall health and can potentially harm them if not used carefully.
