A clarifying shampoo is specifically formulated to remove buildup of products, natural oils, and impurities from the hair and scalp. This is crucial before a chemical service because residue from styling products or oils can hinder the effectiveness of chemical treatments such as coloring, perming, or relaxing. By using a clarifying shampoo, the hair is thoroughly cleansed, allowing for better penetration and absorption of the chemicals used in these services, leading to more consistent and desired results.

In contrast, while moisturizing, color-protecting, and hydrating shampoos serve important purposes such as adding hydration and maintaining color-treated hair, they do not effectively cleanse the hair of buildup in the same way a clarifying shampoo does. Their primary effects are more about enhancing moisture or preserving color rather than preparing the hair for chemical processing, making them less suitable before such treatments.
