| dc.description.abstract | Polyherbal hair dye products are preferred over synthetic products due to their several
bene ts. Literature reported flowers of Hibiscus rosasinensis, seeds of Coffea arabica,
buds of Syzygium aromaticum, and bark of Cinnamomum zeylanicum extracts seem to
have high colour intensity. Hence, this study aimed to prepare a Poly Herbal Hair
Dye (PHHD) cream using aqueous and alcoholic extracts of above plants. Aqueous and
ethanolic extracts were obtained after maceration. PHHD creams (A,B,C) were prepared
mixing each extract with the cream base. A hair color developer was prepared to
improve the colour retention of the hair by adding hydrogen peroxide in 3% ,6% and
9% concentrations, separately. The formulated PHHD creams and the developer were
evaluated for organoleptic and physicochemical properties. The hair colorant e ect of
each cream and their combinations with the hair color developers were evaluated using
human gray hair. Formulated creams were characterized by microscopic analysis, stability
test, analyzing the effect of sunlight, natural detergent and room temperature on coloured
gray hair. Descriptive analysis was done using SPSS 23. The ethanolic extract exhibited
high color intensity. All the types of hair color developers had the same colour effect
on gray hairs. Nine percent of developers had the longest duration (45 days) of colour
retaining ability. The six percent of developers were selected as the suitable developer
considering its median peroxide level and the duration of colour retention. Hence, it could
be concluded that the combination of PHHD B (Ethanolic) with 6% developer would be
suitable for hair dyeing due to its high colour intensity, colour retention time (30 days)
and the level of hydrogen peroxide. | en_US |
