What is one key benefit of using conditioner after shampooing?

Using conditioner after shampooing provides moisture and manageability to the hair, which is one of its primary purposes. Shampoo cleans the hair by removing dirt, oil, and product buildup, but it can also strip the hair of its natural oils, leading to dryness and frizziness. Conditioner is formulated to replenish moisture, smooth the hair cuticle, and make the hair easier to detangle. This results in softer, shinier, and more manageable hair, enhancing its overall appearance and feel.

The other choices do not accurately represent the main purpose of conditioner. While some products may help with hair strength, conditioning is primarily about hydration and smoothness. Conditioning does not remove buildup from shampoo, color the hair, or provide a permanent strengthening effect; these functions are associated with other hair care products.
