Abstract

The invention discloses an ecological plant hair dye and a preparation method thereof. The ecological plant hair dye comprises a coloring agent and a dyeing auxiliary, wherein dyes in the dyeing agent are tannic acid and radix isatidis, and the dyeing assistant in the dyeing auxiliary is a ferric salt or a ferrous salt. The dyes of the hair dye disclosed by the invention are the tannic acid and the radix isatidis, which are both natural components extracted from Chinese medicinal herbs, are nontoxic and harmless and have a certain medicinal function; during hair dyeing, the dyes are complexedwith the ferric salt or the ferrous salt in the dyeing auxiliary to generate a black complex so that human hairs are dyed in a black color; the adding of the dyeing auxiliary to the coloring agent also can help the dyes permeate into the hairs so that human hairs are easy color. The hair dye disclosed by the invention contains no chemical synthetic dye, and has the advantages of high dyeing rate,natural color after dyeing, good glossiness, washing resistance and sun resistance; and compared with chemical synthetic dyes, the hair dye in the invention is a safer ecological hair dye with lower toxicity.

Description

technical field [0001] The invention relates to the technical field of hair dyes, in particular to a plant ecological hair dye and a preparation method thereof. Background technique [0002] Most of the currently commercially available hair dyes are oxidative permanent hair dyes, and their main dyeing intermediates include p-phenylenediamine, p-aminophenol, o-phenylenediamine, etc., because these substances have certain toxicity and allergies, Therefore, cases of allergies caused by the use of such hair dyes occur from time to time, and the degree of adverse reactions is relatively serious. The main manifestations are local itching, tingling, accompanied by local erythema, edema, and blisters. In severe cases, exudation may occur , even a large area of ​​head and face edema and even systemic adverse reactions, and it has been reported that this type of hair dye has the possibility of carcinogenicity. How to develop a hair dye that is safe, low in irritation, and has no side...
