This is a cosmetic product designed to neutralize unwanted warm tones in hair. Often employed after bleaching or highlighting, it aims to counteract brassiness, resulting in a cooler, more balanced final color. For example, if hair displays excessive reddish or golden hues post-treatment, this item can help achieve a more neutral blonde or light brown shade.
The value of such a product lies in its ability to refine hair color without the need for further harsh chemical processing. It offers a gentler approach to achieving the desired tone, minimizing potential damage and dryness. Its introduction addresses a common concern among individuals who lighten their hair, providing a convenient solution for managing undertones that can detract from the overall aesthetic.
