A one-off improvement is not the same as control
A lawn can absolutely look better after a tidy-up or even a decent first treatment. The problem is that improvement and control are not the same thing. A property can look fixed for a short window while the underlying cycle is still active.
That is why recurring weeds are such a common pain point. People are not imagining it - the lawn really can slide back quickly if nothing is staying on top of the pressure.
