In this composite picture, we have two items (ignoring the background). First there is a bottle of shampoo and second is the bed. This puzzle is all about placement. The bottle of Head and Shoulders (TM Procter & Gamble) is above the bed. The bed is a symbol of rest. So the cliche pictured is Head and shoulders above the rest. Apparently the difficulty level of this puzzle was just that as only one person got the correct answer.
