heads off
Intercepts before arrival
Heads off means to intercept or block something before it arrives or develops.
You might head off a problem by addressing it early, or head off a person by cutting across their path: Security headed off the protesters before they reached the building.
The phrase suggests preemptive action—stopping something by getting ahead of it rather than confronting it directly.
