Using a clarifying shampoo primarily serves to remove product buildup from the hair and scalp, which can occur from styling products, hard water, and environmental pollutants. This buildup can weigh hair down, dull its appearance, and hinder the effectiveness of other hair products. By stripping away these residues, a clarifying shampoo prepares the hair for subsequent treatments or products, allowing them to penetrate more effectively and perform as intended.

The other options highlight benefits related to different types of shampoos or treatments. Enhancing color and adding shine is more characteristic of shampoos designed specifically for color-treated hair, while moisturizing and nourishing is a primary function of hydrating or conditioning shampoos. Strengthening and protecting hair typically refers to specialized treatments aimed at reinforcing hair structure and preventing damage. Thus, while those properties are important, they do not reflect the primary purpose of a clarifying shampoo.
