Which of the following describes a possible outcome of improper hydration?

Improper hydration can lead to increased brittleness and weakness in the nails. When nails are not sufficiently hydrated, they may become dry and more susceptible to damage. Consequently, this results in an increased likelihood of nail breaking, as the structural integrity of the nails diminishes. Proper hydration is essential to maintain flexibility and strength in the nail structure, which helps prevent breakage. The other options, such as stronger nails, reduced brittleness, and improved polish retention, are all benefits of adequate hydration and do not reflect the consequences of improper hydration.
