Problems solved by technology
There are three problems with this type of product. First, the fastness does not meet the standard of permanent hair dyeing, that is, the color will not fade for 40-50 days after dyeing
2. Inconvenient to use: it needs to be dyed three times under heating conditions. 3. When the hair dye touches the skin, the skin is easy to dry
However, there are still two problems in use. One is that the hair dye is not easy to wash off when it touches the scalp, and hair dyeing requires professional skills.
Second, it needs to be heated twice
Although the hair dye is used by more than 20,000 person-times in Shanghai every year, due to the above-mentioned problems, the promotion of the product has been affected objectively.

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 visualizationreagent 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.
