In the ads above one can clearly see the women's perfect hair, that have no fly aways, are shiny, and volumized, pretty much the way most girls want their hair to look like. However, a lot of them know that the style that is seen on the ads for shampoo bottles rarely works. Although, the companies of many shampoo producers have tricked people into believing that if they use their product then their hair will also look like this. By putting beautiful girls on their posters who have amazing hair/ styling the models hair to look like that they are catching the consumers eyes. Which is exactly what they want, however, the size of the models takes up more space on the poster than the product itself. It seems like they producers are banking more on what they put on the poster to work better than just showing off their products. Showing off what could happen if they used their products.
This is an example of classical conditioning because the consumers are tricking the producers into believing that by using our products your hair could look like this too. And people believe it, and thus buy the products in hope of getting their hair to look like that too. Thus they have fallen prone to the aspect of a conditioning stimulus. The consumers and glad that by using this process they can have people buy their products.
