What is the primary purpose of a conditioner?

The primary purpose of a conditioner is to restore moisture and improve manageability. Conditioners are formulated with hydrating ingredients that help to replenish lost moisture in the hair, which can be stripped away through washing and environmental factors. After cleansing the hair with a shampoo, which may remove natural oils, using a conditioner helps to smooth the hair cuticle, making the hair feel softer and easier to detangle. This improved hydration not only enhances the overall texture of the hair but also makes it more manageable, reducing frizz and allowing for easier styling.

While cleansing the hair is the main role of shampoo, enhancing hair color typically falls under the domain of hair color products or special color-depositing conditioners, rather than basic conditioners. Creating volume often involves styling products or techniques rather than conditioning treatments, which generally focus on moisture and smoothness rather than adding body. Therefore, the correct choice accurately reflects the fundamental function of a conditioner in hair care.
