答案

Well, I think so. There are some reasons. Firstly, people tend to be convinced by famous brands. It is understandable for people to consider that products in large-scale advertising tend to be in higher quality, as when the manufacturer spends a great amount of money on advertisement, so will it on ingredients. Moreover, people will be substantially influenced by acquired knowledge. This is particular when we’re in an urgent need of purchase. For example, when we’re in a rush and want to buy a shampoo. What’s first come into mind, Head & Shoulders? Then that’s it, without a second thought, because the advertisement of Head & Shoulders appears on majority of TV channels every day.
