@katiefoothealth: Covering a damaged or fungal nail with polish might make it look better short-term, but it actually makes things worse. Nail polish traps moisture and blocks airflow, creating the perfect warm, dark environment for fungal infections to thrive. It can also mask changes in colour, thickness, and shape—meaning the condition often goes untreated for longer and becomes harder to manage. On top of that, removing and reapplying polish (especially with harsh removers) can further weaken an already compromised nail. Healthy nails need to breathe, be kept clean and dry, and treated properly—not covered up. If you can’t see it, you can’t treat it.
