Shampoo

Shampoo is a hair care product used to cleanse the scalp and hair. It typically contains surfactants, which are molecules that help to lift dirt and oil away from the hair, and can also contain other ingredients such as fragrances, colorants, and preservatives. Shampoo can have medicinal properties, as some formulations are designed to help address certain scalp and hair conditions. For example, shampoo can contain ingredients such as tea tree oil, which is known for its antimicrobial and antiseptic properties, or aloe vera, which is known to soothe and moisturize the scalp. Other medicinal shampoos may contain ingredients that treat conditions caused by fungal infection, such as dandruff. These shampoos may contain active ingredients such as selenium sulfide and zinc pyrithione, which help to reduce the presence of fungi on the scalp and reduce flaking. In addition, some shampoos contain ingredients that help to control hair loss and promote hair growth, such as biotin and saw palmetto.
