bleaching

Bleaching is a process used to lighten or whiten materials, typically fabrics, hair, or teeth, by removing or breaking down their dark or colored compounds. This is achieved through chemical agents such as hydrogen peroxide or chlorine, which interact with the molecules responsible for color, often breaking bonds or oxidizing them. The result is a reduction in pigmentation, making the material appear brighter, whiter, or more uniform in color. Bleaching is commonly used in laundry, hair styling, and dental treatments to enhance appearance, but it must be carefully controlled to avoid damage.
