Using a conditioner primarily serves the purpose of hydrating and smoothing the hair. Conditioners contain moisturizing agents and emollients that help to improve the hair's texture, making it softer, shinier, and more manageable. They work by coating the hair shaft, reducing friction, and helping to align the cuticles, which can lead to smoother strands and alleviate dryness or frizz. This hydration is essential for maintaining the health of the hair, especially for those with damaged or color-treated locks.

In contrast, adding color to the hair is typically the function of hair dyes or color treatments rather than conditioners. While some products might offer color-enhancing properties, they do not serve the fundamental purpose of conditioning the hair. Similarly, increasing curl definition is more associated with styling products specifically designed for that purpose, rather than a standard conditioner. Lastly, while conditioners may aid in the removal of tangles left by styling products, they are not primarily designed to strip products from the hair; that function is more aligned with clarifying shampoos. Thus, the correct understanding of a conditioner is that it is meant to hydrate and smooth, making option B the most accurate choice.
