Bleach and Tone When the hair is bleached in a separate step from the coloring process, it is called "Bleach and tone". More of the orginal or tinted color can be lifted for a more exact color result using this process. If the hair has a lot of stain from previous color applications, then a dye solvent needs to be used first. This process is listed under "Corrective Works". It is time consuming and expensive.
Up to 40 vol. peroxide with enhancing products added.
