Rinse, or conditioner, is It coats the hair to prevent moisture from escaping. If your hair is excessively dry, leading to frequent static electricity or tangling, it is recommended to use conditioner. Conditioner can be used daily after shampooing; apply it to your hair, avoiding the scalp, and rinse thoroughly with water after 1 to 2 minutes. Since conditioner acts as a coating that can clog the scalp, special care must be taken to avoid contact with the scalp, and there is no need to leave it on for too long.
