What are products used to equalize hair porosity and eliminate unwanted color called?

1. Neutralizers

2. Fillers

3. Conditioners

4. Hair Masks

The correct answer is: Fillers

Fillers are specifically designed to balance hair porosity, which is crucial in achieving even color results during hair coloring processes. When hair has uneven porosity, some areas may absorb color more intensely than others, leading to patchy or inconsistent results. Fillers work by treating the hair to ensure that all strands absorb color uniformly, which is particularly important when going darker or when attempting to refresh or correct color. In contrast, neutralizers are typically used in the context of chemical processes such as perming or relaxing, helping to stabilize the hair structure post-process. Conditioners primarily focus on moisturizing and nourishing the hair, improving its overall texture and health, but they do not specifically address porosity issues. Hair masks provide intensive treatment and hydration but are also not focused on equalizing porosity or correcting color. Therefore, fillers are the ideal choice for achieving uniform color by balancing the hair's ability to absorb color products.
