What is the main function of a hair conditioner?

To moisturize and enhance the appearance of hair
To add color to the hair
To protect the hair from heat

The correct answer is: To moisturize and enhance the appearance of hair

The primary function of a hair conditioner is to moisturize and enhance the appearance of hair. Conditioners are formulated with various ingredients that help to soften hair, reduce frizz, and improve manageability. They work by coating the hair shaft, which can smooth the cuticle layer, leading to a shinier and healthier-looking finish. This moisturizing effect can also help detangle hair, making it easier to style and reducing breakage. While cleansing products serve to remove oils and dirt, conditioners focus on replenishing moisture and vitality to the hair. Additionally, conditioners do not add color; that function is served by hair dyes or color products. Heat protectants address a different need, as they prepare the hair for styling processes involving heat but do not inherently moisturize or enhance appearance in the same way conditioners do.
