Abstract

The invention relates to a non-oxidative permanent type natural melanoid hair water and a preparation method thereof. The melanoid hair water is prepared with natural materials and is formed by No. 1 hair dye and No. 2 hair dye. The No. 1 hair dye takes clove as an osmotic agent, takes cysteine as a reducing agent, takes nutgall, myrobalan and gallnut as the paints and takes angelica as a nutrition component; the No. 2 hair dye takes copperas as a visualization reagent and leads the copperas to be aggregated with the dye component of the No. 1 hair dye into a black paint giant molecule. The invention, on the basis of the application of a traditional Chinese medicine osmotic agent, also applies a natural reducing agent of the cysteine to cut off a hair keratin disulfide and increase the hair fasciola clearances, to lead the traditional Chinese medicine paint molecule to be easier to enter the hair fasciola clearances and lead the melanoid hair to be blacker and firmer; while the hair dye is easy to wash when contacting the scurf and can be used only by heating for one time. The invention is easyto be accepted by more consumers.
