Fillers are used for all of the following EXCEPT what?

Fillers are substances used in hair coloring to achieve various results, particularly when altering hair color. They are specifically designed to help balance the color and improve the overall look of the hair by addressing issues like porosity and color depth.

Producing gray coverage typically requires a permanent hair color or specific formulations designed for that purpose, rather than fillers. Fillers support the coloring process by enhancing colors, equalizing porosity, and helping to achieve deeper tones, but they are not primarily used for gray coverage. They function more effectively in pre-treating the hair prior to coloring to ensure a more even application and a successful end result.

Understanding the role of fillers in enhancing color results, equalizing porosity, and creating deeper color tones helps clarify their main functions versus the incorrect assumption that they can produce gray coverage. This distinction is important for achieving optimal coloring outcomes in cosmetology practices.
