What is the primary function of conditioner?

The primary function of conditioner is to improve manageability and strength. Conditioners are formulated to moisturize and nourish the hair, making it easier to detangle and style. They often contain ingredients that help to smooth the hair cuticle, reduce frizz, and enhance shine, leading to improved overall hair health and appearance. This process not only makes the hair easier to manage but also fortifies it against damage from heat styling and environmental factors.

Conditioners do not play a role in cleansing the hair; that is the function of shampoo. They also do not remove all dirt from the hair, as that is specifically the task of cleansing products. While some leave-in conditioners or treatments can temporarily enhance color, adding color to the hair is not a primary function of conditioners in general.
