2. Developers

The higher the volume of the developer, the greater the amount of sulfur is removed from the hair structure. This is one of the reasons why the limitations of the developers be maintained at 30 volume or less for the majority of haircoloring. When we lighten natural hair, the oxidation of the melanin will give a reduction of the natural pigments. Decoloration will have an effect on the natural pigments. They will act especially on the granular pigments and will act progressively as the action of the decoloration takes place. The granular pigments will transform into diffused pigments which explains the apparitions of the reflect more or less intense as the decoloration processes.
