How does Basic Red 22 work?

Basic Red 22 acts as a hair dye by binding to the keratin proteins in the hair. It does not penetrate deep into the hair structure, but rather remains on the surface. This means that it creates a temporary or semi-permanent coloration that washes out over time. The color intensity depends on the concentration of the dye, the application time and the condition of the hair.
