The function of a clarifying shampoo is primarily to remove product buildup from the hair. Over time, products such as styling gels, hairsprays, and other hair care products can accumulate on the hair and scalp, leading to dullness, weighed-down hair, and decreased effectiveness of regular shampoos and conditioners. Clarifying shampoos contain stronger detergents and agents designed to deeply cleanse and eliminate these residues, allowing hair to regain its natural vibrancy and making it more receptive to subsequent treatments and products.

In contrast, adding moisture to dry hair typically involves hydrating shampoos or conditioners that are formulated to lock in moisture, rather than stripping it away. Removal of color from hair is a task usually reserved for color removers or bleach, rather than a clarifying shampoo, which focuses on cleansing rather than altering hair color. Enhancing the hair's shine is often the function of conditioning or shine-enhancing products that help to reflect light rather than clarifying shampoos that target cleansing.
