PVP, as a cosmetic ingredient, is most importantly used in hair styling products. It possesses many excellent properties and is an indispensable raw material for hair gels, lotions, and mousses. PVP has good film-forming characteristics, allowing it to create a transparent film with good affinity, which is easy to rinse off with water, non-irritating, and hypoallergenic. It provides good protection for the hair and serves as a setting agent and film former in personal care products like mousses and hair gels. When PVP adheres to the hair, it forms an invisible film that helps to fix the hairstyle, making it long-lasting and shiny without attracting dust. When the hair becomes disheveled, it can be easily re-styled; it can be washed off with shampoo when not needed
