A clarifying shampoo is specifically designed to remove buildup from products such as styling gels, sprays, and conditioners, as well as residues from hard water. Over time, these products can leave a layer on the hair that dulls its appearance and can hinder the effectiveness of other hair care products. Using a clarifying shampoo allows for a deep cleansing that restores the hair's natural luster and prepares it to better absorb nutrients from regular shampoos and conditioners.

When considering the other situations: hydrating dry hair typically requires moisturizing shampoos or conditioners with hydrating properties, maintaining color-treated hair often involves color-safe shampoos that prevent fading, and soothing an itchy scalp would be better addressed with medicated or soothing shampoos designed for that particular concern. Thus, clarifying shampoo is uniquely suited for the purpose of removing buildup, making it the most appropriate choice in this context.
