The sensory panelists are recruited through some general criteria suggested in International Standard Sensory Analysis – General guidelines for the selection, training and monitoring of selected assessors and expert sensory assessors but for hair product evaluation, some hair criteria should also be considered, as a major challenge lied in the difficulty to recruit panelists. Such an issue led us to find practical solutions to make this recruitment easier. Among others, one possible solution was to restrict some requirements in the characteristics of hair. This study aimed at checking if a hair type diversification on either sensitization or curliness could influence the sensory perception of shampoos, and, if so, to which extent. This study demonstrates that, for a shampoo trained panel, the evaluation is impacted by the hair curliness but is not impacted by the hair sensitization level.
