What are permanent, or traditional, toners applied to?

Permanent toners are specifically designed to enhance or alter the color of pre-lightened hair. This means they are most effective when applied to hair that has already undergone a bleaching or lightening process.

When hair is pre-lightened, the underlying pigments are lifted, creating a blank canvas that allows toners to deposit new colors more vibrantly and accurately. Toners help to neutralize unwanted tones, such as brassiness, and can add softness, brightness, or specific hues to the hair.

In contrast, the other types of hair listed, such as unbleached, colored, or natural hair, may not benefit from permanent toners in the same way since these toners are tailored to work on hair that has already been lightened. They may not produce the desired results on hair that retains its natural pigments or has other color treatments, as there may not be a suitable base for the toner to act upon effectively.
