Photo of Product in Use - Question

Good question. What i would do is, after using it for a few days you can work out whether it gives a good lather or whether its more emollient and softer without many bubbles, then one day step out of the shower, put a robe on and just take a picture of your hair showing the lather. OR you could just rub it between your hands to display the amount of lather it produces. I think its really just to show the product in use, but obviously if its in a personal environment like the shower, you can be creative with the picture and not necessarily show it in use IN the shower. Even just squeeze some onto your palm and show the consistency.
