Which product is used to equalize porosity?

1. Fillers

2. Color remover

3. Conditioner

4. Shampoo

The correct answer is: Fillers

Fillers are specifically designed to equalize porosity in the hair during the coloring process. When hair is color-treated, especially if it has been previously lightened or damaged, the porosity can become uneven. Areas of high porosity absorb color more quickly, while areas of low porosity take longer to process. By using a filler, which often contains a dye or pigment and conditioning agents, the stylist can help to normalize the absorption levels across the strands. This step is crucial in achieving a more uniform color result and ensuring that the final appearance is consistent throughout the hair. While color remover, conditioner, and shampoo all serve important functions in hair care, they do not specifically address the issue of porosity in the same way that fillers do. Color removers are meant to strip existing color from the hair, conditioners primarily focus on moisturizing and improving the hair’s condition, and shampoo is used for cleansing. Each of these products plays a role in overall hair care and maintenance, but when it comes to equalizing porosity for color application, fillers are the targeted solution.
