If you're using a topical nail product and wondering why results take a while, it comes down to basic biology.
Toenails grow at roughly 1-2mm per month on average — much slower than fingernails. A full toenail replacement can take up to 12-18 months.
Any improvement in appearance shows up first at the base of the nail, where new growth emerges — not on the already-damaged portion further out. That's why noticeable change takes months, not days.
Early signs like reduced odor or softer surrounding skin can appear within weeks, but full cosmetic change tracks the natural growth timeline. Patience and consistency matter more than any single ingredient.
