What is the function of an intensifier in hair coloring?

An intensifier in hair coloring is used primarily to create a more vivid look. It enhances the depth and richness of the color, making it more vibrant and noticeable. Intensifiers are often added to hair color formulations to boost specific tones, whether that's enhancing reds, giving added brightness to blondes, or deepening the richness of browns. This is particularly useful for achieving the desired result in fashion colors or to enhance the overall appearance of a color service.

In contrast to this, lightening hair color involves different processes and products, such as bleach or lightening agents, which is not the role of an intensifier. Neutralizing unwanted pigments also requires specific color-correcting agents or tones rather than an intensifier. Similarly, equalizing porosity is related to hair preparation techniques rather than the coloring process itself. Thus, the role of an intensifier is specifically aimed at making colors more vibrant and impactful.
