Powder bleach for hair is a chemical lightener used to remove natural hair pigments, allowing for different hair colors. Hydrogen peroxide is a common active ingredient, which oxidizes melanin, the pigment that gives hair its color.
The process of bleaching can lift hair several shades at once, making way for bolder hair colors like platinum blonde or pastel hues. Peroxide-based powder bleach became a popular commercial product in the 1940s, revolutionizing the hair industry and enabling new levels of hair customization.
