Shampoo

From WikiMD's Wellness Encyclopedia

Shampoo is a hair care product, typically in the form of a viscous liquid, that is used for cleaning hair. Less commonly, shampoo is available in bar form, like a bar of soap. Shampoo is used by applying it to wet hair, massaging the product into the hair, and then rinsing it out. Some users may follow a shampooing with the use of hair conditioner.

History[edit | edit source]

The word shampoo entered the English language from India during the colonial era. It dates to 1762, and is derived from Hindi chāmpo (चाँपो [tʃãːpoː]), itself derived from the Sanskrit root chapayati (चपयति, which means to press, knead, soothe).

Ingredients[edit | edit source]

Shampoo is generally made by combining a surfactant, most often sodium lauryl sulfate or sodium laureth sulfate, with a co-surfactant, most often cocamidopropyl betaine in water to form a thick, viscous liquid. Other essential ingredients include salt (sodium chloride), which is used to adjust the viscosity, a preservative and fragrance.

Types of Shampoo[edit | edit source]

There are various types of shampoos available in the market such as 2-in-1 shampoo, baby shampoo, animal shampoo, colored hair shampoo, and many more.
