No. Blood from the head returns to the right side of the heart and is then pumped ino the lungs.
The blood from the head returns to the heart and is then sent to the lungs. If it went to the lungs before returning to the heart, that would be wasteful becase then it would have gone through the lungs twice before going to where it was needed.

Why is the blood flowing to the heart oxygen-poor while the blood flowing to the rest of the body is oxygen-rich?
When the blood is flowing back to the heart, the blood has already given off its oxygen to the rest of the body which means it contain less oxygen concentration in the blood. and when blood is flowing from the heart to the rest of the body, the blood contains high level of oxygen because they were being given oxygen by the lungs which passes along the heart and the heart pumps it to the rest of the body.

Why are there four valves in the heart?
2 of these valves (one on each side) stop blood from flowing back into the atria chambers of the heart when the heart is contracting and expelling blood. The other two are there to stop blood flowing out of the ventricles when the heart is filling up with blood. One stops blood flowing through the aorta to supply the body and the other stops it flowing through the pulmonary artery to the lungs.
