Systemization of a method to dye white hair in bright colors

This study attempted to explain a principle of dying gray hair in bright colors and carrying out microscope-used experiments to find out if gray hair could be dyed in bright colors. This study tried to reduce the brightness difference by treating natural hair with bleaching agent and 9% oxidizer in the same way as hairdressers commonly do at present, and then observed the outcome. Many people think gray hair cannot be dyed in bright colors, but by explaining this possible method to dye gray hair in bright colors and verifying it through experiments, this study has significance in establishing this method systematically. In order to dye the gray color with bright color, it is necessary to match the background color and the gray color with the same brightness and dye with bright color.
