Shampoo

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

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

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

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.

Health Impact

Some health issues are associated with the frequent use of shampoo such as itchy scalp, dandruff, and sometimes hair loss.
