Description

Method for preparing hair dye oil by using natural plants Technical Field The invention belongs to the technical field of hair dye preparation, and particularly relates to a method for preparing hair dye by using natural plants. Background Hair dyes are common hair-dressing products in daily life of people, and especially for white hair caused by hereditary, metabolism, nutrition, diseases, aging and other reasons, the black hair dyes are quite required. In addition to the white hair caused by the aging, the white hair crowd is gradually younger and the demand for black hair dye is more and more increased along with the acceleration of the life rhythm and the deterioration of the natural environment in recent years. The early hair dye takes inorganic coloring agent as main material, and the metal ions in the hair dye penetrate into hair to react with the sulfur of cysteine in hair protein to generate black lead sulfide, thereby realizing black dyeing. However, the accumulation of heavy metal ions in hair dyes causes poisoning to human body, and the damage to hair is serious, and in addition, the hair health is damaged, and allergies and other diseases are caused. Along with the progress of scientific technology, the synthetic hair dye is pushed out, the active ingredient of the synthetic hair dye is aniline dye, such as p-phenylenediamine and derivatives thereof, and the like, but the synthetic hair dye has high sensitization, and various cancers such as skin cancer and the like can be caused after long-term use.
