Hair rinses are a special category of hair conditioners designed as thin liquids applied like an instant hair conditioner after shampooing and rinsed. They utilize cationic quaternary ammonium compounds, such as stearalkonium chloride and benzalkonium chloride. These products are mainly used to facilitate hair detangling by reducing friction and do little else to condition the hair shaft. They are intended for persons with oily hair who need little conditioning due to abundant sebum production.
