ABSTRACT

The use of natural dyes as an alternative to synthetic dyes has gained popularity in recent years due to concerns over the potential health risks associated with the use of synthetic dyes. Cassia fistula, a species of tree native to the Indian subcontinent and adjacent regions of Southeast Asia, has been used as a natural hair dye in many parts of the world. However, the use of natural dyes as hair dyes is often limited by their poor stability and poor color payoff. In this study, we report the preparation of demipermanent hair dyes gels from ethanol extract of Cassia fistula using carbomer as a gelling agent. The effect of carbomer concentration on the viscosity and rheological properties of the gel was investigated, and the stability of the gel was evaluated under various conditions. The color payoff and stability of the gel were also assessed and compared to those of a commercial demipermanent hair dye. The results showed that the gel prepared with 1% carbomerhad the highest viscosity and exhibited excellent stability under various conditions. The gel also showed good color payoff and stability, and was comparable to the commercial demipermanent hair dye. This study demonstrates the potential of using Cassia fistula as a natural hair dye and the use of carbomer as a gelling agent to improve the stability and color payoff of natural dyes. If we add Hibiscus flower powder to the Cassia fistula powder and then gel based hair dye is made then it produces reddish shade to the hair as Cassia fistula produces golden yellow color on light coloured hairs. Also hibiscus provides protection against bacteria and fungi.
