The primary function of conditioner in hair care is to moisturize and detangle hair. Conditioners are formulated with ingredients that help to hydrate the hair strands, making them softer and more manageable. This hydration is crucial because hair can become dry and brittle due to various factors like environmental exposure, heat styling, and chemical treatments. A well-moisturized hair shaft not only has improved elasticity but also looks shinier and healthier.

Additionally, conditioners contain ingredients that help reduce friction between hair strands, which aids in detangling. This makes it easier to comb or brush the hair, reducing the risk of breakage. The use of conditioner after shampooing, which often strips the hair of its natural oils, helps restore moisture and maintain the hair's overall health.

While straightening and coloring hair or protecting against heat are important aspects of hair care, they are not the primary functions of conditioner. Straightening and coloring typically involve different products and techniques, while heat protection requires specific ingredients designed to shield hair from thermal damage.
