Embodiment Construction
[0028] The protective agent against hair dye allergy can be applied to the hair dye containing p-phenylenediamine, wherein the ratio (by weight) of the hair dye to the protective agent can be 1:1.0-2.0. A better ratio is 1:1.5.
[0029] In the preparation of the protective agent against the excessive consumption of hair dyes, the method of plant purification is as follows: firstly, the plants to be purified are washed, water-cut at room temperature, and dried; Ionized water mixture, the ratio of butanediol and deionized water is 2-4: 6-8 (that is, butanediol is 20-40%, and the rest is deionized water), made into an aqueous extract, at 60-80 Extract at ℃ for 8 hours; finally reduce the pressure and remove the solvent at 20℃ to obtain the extract, which is dissolved in 0.001-0.1% potassium persulfate and 0.002-0.2% sodium persulfate solution with a ratio of 1:1.
[0030] In the research of the present invention, an animal model has been established, the curative effect a...
