Abstract
In the present invention there is provided a single-step process and composition of hair bleach, which can simultaneously lighten the hair up to seven levels and effectively neutralize any undesirable warmth, provide natural tones or deposit fashion shades. This is achieved by including in the bleach mixture a solution containing basic dye molecules, which in the present invention have been found to be both, stable in the bleach, and capable of depositing the desired amount of tone on the hair. The dyes fall into the class of water-soluble basic azo compounds.
