Development and Evaluation of Polyherbal Hair Dye Formulation

Abstract

Background and objectives: Hair care products including hair dye play an important role in the maintenance and enhancement of appearance and overall wellbeing of the hair. Most of the hair dye available in the market contains harmful chemicals that may cause allergic reactions or irritation of the scalp. The objective of this study focuses on the formulation and evaluation of hair dye as creams and gels with different shades by using herbs. Methodology: The collected plants were authenticated, and shade dried. Then, extractions were done using water, ethanol, and methanol. Preliminary testing was conducted to obtain burgundy, brown and black by manipulating the ratios. Later, almond oil, coconut oil, beeswax and Carbopol-934 gel were added to ease the penetration. Finally, accelerated stability studies were done to check the physical and microbial stability of the product. Results: Eight different shades of hair dye were formulated in gel and cream form. Among them gel formulation F5 and F6 as well as the cream formulations F1, F2, F3, F4, F7 and F8 demonstrated good staining and better colour intensity. The accelerated stability studies of F1 to F8 revealed that there is no change in the physical evaluation and no evidence of microbial contamination. Conclusion: The output of this research is suitable for all races and age group because it is not a permanent hair dye that might have a restriction for some groups of races. As such, this hair dye is fully formulated with natural sources by considering in the reduction of severe side effects to the consumers.
