Since the early 20th century, the term shampoo has also been used for commercial liquid soap products for washing hair. Shampoo is designed to produce plenty of lather that removes dirt, without removing the natural oils that protect the hair. The product is made slightly acidic to cause the hair to contract slightly, giving it a shinier appearance. It is possible to make mild shampoos at home with natural ingredients for daily wash. Shampoos should be chosen according to hair types. Some shampoos also contain hair conditioners.

Well-known shampoo brands include:

• Head & Shoulders
• Clairol
• VO5
• Pantene
• Suave
• Paul Mitchell
• Samy's Samy Products
