In the article, the author is expressing his doubts whether shampoo should be applied twice because it is better for the hair or because marketers told us so. A simple word “repeat” can double the sales. I liked this article because it makes people think if they have to follow instructions without giving it a second thought and try to evaluate how relevant they are.
This article made me think as well. What are other similar marketing strategies that are aiming at increasing sales? First example that is coming to mind is advertisement of Tic-Tac, Life Saver, and different chewing gums. In their commercials, models never have just one piece. They are showing customers an example of what exactly they should do with their product. Strange as it may seem, a big part of company’s target market actually follow this example.
However, that are not all the products that are sold this way. A good example is toothpaste. In this case, people usually do not put that much toothpaste on a brush that it is advertised. It is quite obvious that the amount of it in different commercials is definitely exceeded. Still, it is possible that this trick is done not to make customers to consume more, but just with the purpose for an ad to look better.
People see how the product is used in the commercial, so without even thinking he or she is repeating everything in the same way. Do we really need two pieces of chewing gum in order to get rid of bad breath? If so, why the portion has not been increased yet?
