Abstract
Herbal products are being preferred due to the advantages in contrast to the synthetic one which has adverse effect on human health because of harsh chemicals like paraphenylene diamine. The word "Herbal" is a symbol of safety. Thus, our current research was aimed to prepare the herbal hair dye using the herbal extract from the diverse powders of herbals such as, Lawsonia inermis, Aloe vera, Phyllanthus emblica, Thea sinensis, Trigonella foenum-graecum, Eclipta alba, Acacia catechu, Indigofera tinctoria, and Terminalia bellirica. Three different formulations were made by mixing the varying proportion of extract from henna and indigo at the ratio of 1:0, 2:1 and 1:2, respectively. These different combinations of formulation were further evaluated for dyeing effect on unpigmented hair. The results with F3 formulation contain the extract of henna and indigo at a ratio of 1:2 that gave dark brown to black colour to hair, resembling natural hair colour. From our pharmaceutical evaluation studies, the formulation exhibited the better dyeing effect, free from skin irritation, free of obnoxious odour and great retention capacity, benefits of promotion of hair growth, suitable for all age group and ecofriendly on comparison with marketed synthetic dye formulation.
