A moisturizing conditioner primarily functions to add hydration to the hair shaft. This is crucial for maintaining hair health, as hydrated hair is more resilient to damage and less prone to breakage. The ingredients typically found in moisturizing conditioners, such as humectants and emollients, work to attract moisture from the environment and lock it into the hair cuticle, resulting in softer and more manageable hair.

While strengthening the hair shaft is an important aspect of some products, it is not the primary purpose of a moisturizing conditioner, which focuses specifically on hydration. Similarly, removing split ends involves a different process and often requires trimming rather than conditioning. Enhancing hair color is another distinct function that is not related to moisturizing, as color enhancement products are designed for color-treated hair, rather than hydration. Thus, the emphasis on hydration makes the second option the correct one regarding the function of a moisturizing conditioner.
