What component determines a hair color’s intensity?

The concentration of color pigments in a hair color product is crucial in determining the intensity of the color. Higher concentrations of pigment will yield a more vibrant and noticeable hue, while lower concentrations can result in a softer, less intense shade. This is due to the fact that the pigments are the actual agents that provide the color to the hair, and their strength and amount directly influence how bold or subdued the end result appears.

The type of developer used, while important for the overall process of hair coloring, primarily affects the level of lift and how well the color will penetrate the hair rather than specifically impacting the intensity. The texture of the hair can influence how color is absorbed but does not dictate the pigment concentration itself. Similarly, the brand of hair color may have its own formulations and characteristics but does not inherently relate to the intensity of the color, which is fundamentally tied to the pigment concentration.
