Conditioner is a hair care product designed to improve the texture and appearance of hair after washing. It works by moisturizing and smoothing the hair cuticles, making hair easier to detangle and style. Conditioners often contain ingredients like oils, proteins, and silicones that help nourish and protect the hair from damage. There are different types of conditioners, including rinse-out, leave-in, and deep conditioners. Rinse-out conditioners are applied after shampooing and rinsed out after a few minutes, while leave-in conditioners are meant to be left in the hair for ongoing moisture. Deep conditioners provide intensive treatment for dry or damaged hair, often requiring longer application times.
