What is the primary function of conditioner?

The primary function of conditioner is to hydrate and protect hair. Conditioners are formulated with moisturizing agents and substances that help to restore moisture to the hair, making it softer and more manageable. They work by coating the hair strands, which can help to flatten the cuticle layer, reduce frizz, and enhance the overall appearance and health of the hair.

Conditioner also plays a protective role by forming a barrier against environmental stressors, heat damage from styling tools, and the effects of chemical treatments. This protection is essential for maintaining hair’s structure and preventing breakage. Different types of conditioners may also offer additional benefits, such as detangling or smoothing, but hydration and protection are their central purposes.

Other options, while they address aspects of hair care, do not capture the primary role of conditioner as effectively. Cleansing the hair is the main function of shampoo, adding volume typically involves specific styling products, and enhancing color is usually the work of hair dyes or color treatments rather than conditioners.
