The primary function of a hair conditioner is to moisturize and detangle hair. Conditioners are formulated to penetrate the hair shaft, providing hydration that helps prevent dryness and brittleness. This hydration is crucial in maintaining the overall health of the hair, making it softer and easier to manage.

In addition to moisturizing, conditioners often contain ingredients that smooth the cuticle layer of the hair, reducing friction and allowing for easier detangling. This is particularly beneficial for individuals with curly or textured hair, which can be more prone to tangles.

While conditioners may also contribute to making hair shinier and can offer some level of protection from heat styling, their primary role focuses on enhancing moisture levels and facilitating detangling. Therefore, the essence of a conditioner lies in its ability to nurture the hair and make it more manageable.
