Using a hair conditioner primarily benefits the hair by reducing frizz and adding moisture. Conditioners are formulated with ingredients that help smooth the hair cuticle, which can minimize frizz and flyaways, especially in humid conditions. This smoothing effect also results in shinier, healthier-looking hair. Additionally, conditioners provide moisture to the hair strands, which is essential for maintaining hydration, improving elasticity, and reducing breakage. Properly conditioned hair is more manageable and can be easier to style, benefiting both the hair’s appearance and overall health.

While other options describe different hair care products or treatments, they do not represent the primary function of a conditioner. For instance, adding color is typically achieved through hair dyes rather than conditioners. Strengthening hair bonds is often associated with treatments such as protein masks or specialized strengthening serums. Meanwhile, heat protection is generally a feature of styling products specifically designed as heat protectants. Thus, option B correctly identifies a core function of conditioners in hair care.
