Leave-in treatments are hair care products designed to be applied after washing and conditioning the hair. Unlike regular conditioners that are rinsed out, these treatments remain in the hair, providing ongoing moisture, detangling, and protection throughout the day. They come in various forms, including creams, sprays, and serums, catering to different hair types and needs. These products often contain beneficial ingredients like keratin, argan oil, or aloe vera, which help to nourish and strengthen the hair. Leave-in treatments can also reduce frizz, enhance shine, and improve manageability, making them a popular choice for those looking to maintain healthy, beautiful hair.
