The primary function of a conditioner is to moisturize and improve the hair's texture. Conditioners work by replenishing lost moisture, smoothing the hair cuticle, and enhancing manageability. This is important because hair can become dry and damaged due to environmental factors, heat styling, and chemical treatments. A good conditioner can help restore hydration, making hair softer, shinier, and easier to comb through.

While other options present functions that may be associated with different hair care products or services, such as washing away dirt or enhancing color, they do not reflect the primary role of a conditioner. Conditioners specifically target moisturizing properties, which are crucial for maintaining the health and appearance of hair.
