Formulation And Evaluation of Herbal Hair Dye Shampoo

This study focuses on the formulation and evaluation of a herbal hair dye shampoo using extracts from Indigofera tinctoria and Lawsonia inermis. These plants were chosen for their natural dyeing properties, providing an alternative to synthetic dyes that often contain harmful chemicals like ammonia and peroxide. The leaves were extracted using the maceration method, and the shampoo was formulated by combining plant extracts with stabilizers and surfactants. Various physicochemical parameters such as total ash, extractive values, and pH were evaluated. The shampoo demonstrated effective in vitro staining, turning white hair strands black, and exhibited good stability, homogeneity, and washability. These findings suggest that herbal hair dyes are a safer, cost-effective, and eco-friendly alternative to synthetic dyes.
