Shampoo is a hair care product used to clean and remove oils, dirt, and dandruff from the hair. It is typically made up of a mixture of water, oils, and a foaming agent, and can come in various forms such as liquid, cream, or powder. Shampoo is applied to wet hair, massaged into the scalp, and then rinsed out. There are many different types of shampoo available, such as those for dry, oily, or color-treated hair, as well as those for specific hair concerns such as dandruff or hair loss. Some shampoos are also formulated for different hair types, such as curly or straight hair.
