We also have resorted to just quickly dumping the water over their heads. It is honestly so much better than dragging it out! Two other things help us: 1) We wash hair first thing in the tub and just get it over with as quickly as possible (I found the anxiety was building up through the whole bath time b/c we originally did it last). Now we just say "1,2,3" and dump it on their head. Then we say "All done. Now you can play", and 2) Like Laura, we give a towel immediately afterwards to wipe their faces.
