Hair leave-in conditioner, a topical hair care product, is a liquid or cream designed to be applied to damp or dry hair after washing and left in, without rinsing. It provides additional conditioning benefits beyond shampoo and conditioner, improving hair's texture, manageability, and appearance.
Leave-in conditioners are essential for maintaining healthy hair. They hydrate and nourish hair, reducing frizz and tangles, and protecting it from environmental damage and heat styling. Key developments in leave-in conditioner technology include the introduction of lightweight, non-greasy formulas and ingredients that target specific hair types and concerns.
