If the person is close to the camera and the ,helmet, has a distinct color like in your example image i think you can skip the face ,detection, step described above and do just the color ,detection,. Otherwise if the person is far from the camera and there are even multiple persons within the image, doing the face ,detection, and the color ,detection, is a good approach.
