Which shampoo technique is often recommended prior to hair coloring?

Using a clarifying shampoo prior to hair coloring is often recommended because it effectively removes buildup from hair products, oils, and any excess residues. This pre-treating step ensures that the hair is clean and free from substances that could interfere with the color application process. When the hair is stripped of these impurities, the dye can penetrate more evenly and consistently, leading to a more uniform and vibrant color result.

In contrast, other types of shampoos may not be as effective for this purpose. Volumizing shampoos can add body and lift to the hair, but they might not eliminate product buildup. Moisturizing shampoos are designed to hydrate and soften hair, which can be counterproductive before coloring since they may leave residues. Skipping the shampoo altogether could result in uneven color application because any buildup or oils present could prevent the dye from adhering properly to the hair shaft. Thus, using a clarifying shampoo stands out as the most effective preparation technique before coloring hair.
