The invention provides an intelligent temperature-sensitive hair dye capable of reducing aniline substances from entering a human body and a preparation method thereof, and belongs to the technical field of cosmetics. According to the invention, poloxamer solution with temperature-sensitive property is used as a solvent to load aniline dye molecules, so that the hair dye can form gel after contacting human skin, and the release speed of the aniline dye is slowed down, thereby reducing the harm of the aniline dye to human body. And since it is not a gel on the hair, it has little effect on the dyeing effect on the hair. Especially, the oxidative hair dye can be added with different aniline dyes to prepare different colors. |
