If your car still overheats after adding coolant, the problem probably is not the amount of coolant.
A leak, failing water pump, stuck thermostat, clogged radiator, or trapped air can keep the system from circulating properly.
Topping it off may buy time, but it does not fix what is causing the temperature to climb. Coolant should not need constant replacing.
If it keeps disappearing, it is going somewhere.
