What is the primary function of hair conditioner?

The primary function of hair conditioner is to moisturize and improve hair manageability. Conditioners are specifically designed to penetrate the hair shaft, providing hydration and nourishment that help to smooth the cuticle, reduce frizz, and enhance the overall texture of the hair. This process makes hair easier to comb through and style, particularly after washing when hair can become tangled and dry.

While cleaning the hair is the purpose of shampoo, and adding color is associated with hair dyes, conditioners focus on the health and moisture levels of the hair. Strengthening hair typically involves treatments that may incorporate proteins or other restorative ingredients, but moisture and manageability are the key benefits derived from using a conditioner. Therefore, the correct understanding of a conditioner’s role centers on its ability to hydrate and enhance the hair's appearance and feel.
