This document summarizes a research study investigating the role of word-of-mouth and product involvement on impulse buying of cosmetic products. The study developed a research model and hypotheses exploring the relationships between word-of-mouth, product involvement, impulse buying tendency, and impulse cosmetic purchases. Data was collected through questionnaires distributed to cosmetic shoppers in Dubai mall and analyzed using reliability tests, correlation analysis and structural equation modeling. The results found that word-of-mouth had a significant effect on both impulse buying tendency and purchases, while product involvement did not significantly impact tendency or purchases. The study provides suggestions for further exploring these relationships with specific brands, retailers or cultures.
