What does a color filler do?

1. Equalizes porosity

2. Fills the holes

3. Replaces the missing primary colors

4. Lifts color

The correct answer is: Replaces the missing primary colors

A color filler is a type of product used in hair coloring to replace any missing primary colors in the hair. This is important because it helps to achieve a more uniform and vibrant color result. Filling the hair also helps to equalize the porosity, which allows the color to penetrate evenly and last longer. Option A is incorrect because equalizing porosity is a separate step that is done before coloring the hair. Option B is incorrect because while a color filler does fill any holes or gaps in the hair, its main purpose is to replace missing primary colors. Option D is incorrect because lifting, or lightening, color is done with a different type of product called a hair lightener.
