Shampoo is a liquid or gel designed for cleaning the hair and scalp. It contains surfactants that help remove dirt, oil, and impurities from hair strands. The formulation varies to cater to different hair types, such as dry, oily, or damaged hair. Some shampoos also contain conditioners to improve hair texture and shine. Regular use of shampoo can help maintain scalp health and promote clean, manageable hair. Shampoos often come in various fragrances, and some may include added benefits like strengthening, volume-boosting, or color protection, based on individual hair care needs.
