Quick safety note
This guide is educational. It does not diagnose nail fungus or replace medical advice. Ask a qualified healthcare professional before starting a home routine if you have diabetes, poor circulation, thyroid disease, iodine allergy, immune suppression, pregnancy, breastfeeding, open skin, ulcers, or a painful nail.
Why recurrence happens
- Shoes can remain damp.
- Athlete's foot can reseed the nail area.

Signs to restart evaluation

Common questions
How long should maintenance last?
There is no one rule. Many people focus on shoe hygiene and monitoring for several months after visible clearing.
Does iodine prevent recurrence?
No product guarantees prevention; moisture control and skin care matter.
