What is the primary function of conditioner in hair care?

The primary function of conditioner in hair care is to moisturize and detangle hair. Conditioners contain ingredients designed to hydrate the hair shaft, making it softer and more manageable. They work by smoothing down the cuticle, which can become rough or damaged due to environmental factors, chemical treatments, or heat styling. This smoothing effect helps reduce friction between strands, making it easier to comb or brush through the hair, thereby minimizing breakage and damage.

While cleansing the scalp is the role of shampoo, and protecting hair from heat is typically associated with heat protectants, conditioners specifically target the hydration and detangling aspects, which are crucial for maintaining healthy hair. Additionally, while styling products are formulated to help shape or hold a hairstyle, conditioners are focused on the hair's health and appearance rather than styling.
