This document is a project report submitted by Monica Sinha on consumer buying behaviour for hair dyes. It includes an introduction, literature review on hair dyes and colors used, methodology of the consumer survey, results of the survey questions, and conclusions. The survey of 30 consumers in Navi Mumbai found that most consumers in the age group of 19-35 use hair dyes for style and passion reasons, and prefer colors like strawberry blonde and chocolate brown. The report concludes it is important for companies to produce eco-friendly and side effect minimal hair dyes.
