My nana, a repository of time-tested home remedies, swears by a specific trick to reduce the look of thick toenails, and it’s surprisingly simple and effective.

Reality check

A “surprisingly simple trick” might make nails look better temporarily, but:

• it won’t remove fungus
• it won’t permanently thin a diseased nail
• regrowth is common without proper treatment

When to get checked

• nail is yellow, brittle, or crumbling
• it’s getting thicker over time
• pain or pressure when walking

If you want, you can tell me what the “trick” was—I can break down whether it’s helpful care or just another viral myth.
