The primary function of a conditioner is to hydrate and improve the manageability of hair. Conditioners contain ingredients that help to smooth the cuticle, making hair easier to comb and style while adding moisture and shine. This hydration is essential, especially for those with dry, damaged, or chemically treated hair, as it helps reduce tangling and frizz, leading to softer and more manageable strands.

Other options, while they may be related to certain specialized products, do not capture the essential purpose of a standard conditioner. For instance, volumizing products specifically aim to add body and fullness, while strengthening treatments focus on repairing and reinforcing hair structure. Hair coloring products serve a completely different function, aimed at changing the hue of the hair rather than enhancing its health or manageability. Thus, the correct answer emphasizes the core benefit of using a conditioner in hair care routines.
