Formulation and Evaluation of Herbal Hair Dye

Herbal hair care products are becoming popular because they are safer and cause fewer side effects than chemical products. Chemical hair dyes can damage hair and irritate the scalp. So, this study aimed to prepare a herbal hair dye gel using natural ingredients like henna, amla, palash, hibiscus, and reetha. These ingredients help in coloring, cleaning, and strengthening the hair. The extracts of these herbs were prepared and mixed with a gel base made of Carbopol 940, glycerin, methyl paraben, triethanolamine, and distilled water. The prepared gel was evaluated for different parameters such as colour, smell, pH, viscosity, spreadability, homogeneity, and stability. The results showed that the gel had a suitable pH (around 6–7), good thickness, and was easy to apply on hair. It provided natural colour, improved hair texture, and helped in cleaning the scalp due to reetha. No irritation was observed and the gel remained stable during storage. Overall, the herbal hair dye gel was found to be safe, effective, and a good natural alternative to chemical hair dyes, with added benefits for hair health and scalp care.
