Leave-in conditioners are hair care products designed to be applied after washing and left in the hair without rinsing. They help to moisturize, detangle, and protect hair from damage, making it easier to style. These conditioners often contain ingredients like oils and proteins that nourish the hair and improve its overall texture. Using a leave-in conditioner can benefit various hair types, including curly hair and dry hair. They can also provide heat protection when styling with tools like hair dryers or straighteners. Regular use can lead to healthier, more manageable hair, reducing frizz and enhancing shine.
