What does 'Contributing pigment' indicate in hair coloring?

Contributing pigment refers to the underlying tones that exist in the hair itself, which can influence the final color result after a dye is applied. In hair coloring, it is essential to understand that hair is made up of a primary or base color and contributing pigments, which can affect the overall appearance of the hair color once the dye interacts with it.

When coloring hair, understanding the base hues and the contributing pigments helps professionals to predict how the applied color will appear. For instance, if a natural hair color has warm underlying tones, such as red or gold, these pigments will be more visible when a lighter shade is applied, leading to an outcome that might be warmer than expected. This is why recognizing the concept of contributing pigment is crucial for achieving desired results in hair color.

In contrast, the initial color applied refers to the first layer of color used, the temporary change pertains to shades that do not penetrate deeply and may wash out quickly, and the fading process involves how a previous color might diminish over time, all of which do not accurately define the role of contributing pigment in the context of hair coloring.
