A Leave-In Treatment is a hair care product designed to be applied after washing and conditioning hair, without the need to rinse it out. It helps to moisturize, detangle, and protect hair from damage caused by heat styling or environmental factors. These treatments often contain ingredients like oils, proteins, and silicones to enhance hair texture and manageability. Leave-in treatments are suitable for various hair types, including curly, wavy, and straight hair. They can be used daily or as needed, providing ongoing nourishment and protection. Regular use can lead to healthier, shinier hair and reduce frizz and breakage over time.
