The primary function of hair conditioner is to add moisture and improve hair texture. Conditioners are formulated to hydrate the hair, making it softer, smoother, and more manageable. They work by coating the hair shaft, which helps to fill in gaps in the hair cuticle caused by damage or wear. This process not only enhances the overall appearance and feel of the hair but also helps to reduce frizz and improve resilience against future damage.

In contrast, while cleaning the scalp is a function associated with shampoos, conditioning products specifically focus on the hydration and maintenance of the hair itself. Hair coloring products may require conditioners to ensure the hair remains healthy post-treatment, but their primary goal is not to facilitate coloring but to protect and nourish the hair. Similarly, product buildup can be addressed through clarifying shampoos rather than conditioners, which may help detangle and maintain moisture instead of removing residues.
