The general objective of this study is to analyze shopper's behaviour during their purchase intention processes at the retail outlet for the hair care category, specifically shampoo, and provide ELVIVEs brand with relevant information to work on their marketing strategy. A sample composed of 40 female participants within one supermarket store was analyzed and the eye-tracking method was used to analyze their visual attention to different visual stimuli at a retail outlet. The results indicate that the more visual attention the consumer has to a specific shampoo brand, the greater their intention to purchase will be. Likewise, the more the consumer looks at the price of a shampoo brand, the greater their intention to purchase will be. However, not enough evidence has been found to affirm that the more visual attention paid by the consumer to the advertising of a specific shampoo at the retail outlet, the greater their intention to purchase will be.
