Conditioners are specifically designed to moisturize the hair and restore oils and proteins that may be lost due to various factors, such as environmental conditions, heat styling, or chemical treatments. They work by coating the hair strands, providing a layer of moisture that helps to improve the overall health and appearance of the hair. Conditioners typically contain ingredients like humectants, which attract and retain moisture, and emollients, which soften and smooth the hair cuticle.

In contrast, shampoos focus primarily on cleansing the hair and scalp by removing dirt, oil, and product buildup rather than providing moisture or restoration. Stylers are aimed at helping to shape and hold specific hairstyles and do not serve a hydrating or restorative purpose. Rinses are typically used for various effects, like making the hair feel smoother, but they do not contain the same conditioning properties or ingredients that restoratively benefit the hair like conditioners do. Thus, the primary role of conditioners aligns perfectly with the need to moisturize and restore oils and proteins in the hair.
