Shampoo (/ʃæmˈpuː/) 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 scalp, and then rinsing it out. Some users may follow a shampooing with the use of hair conditioner.
The typical reason of using shampoo is to remove the unwanted build-up of sebum in the hair without stripping out so much as to make hair unmanageable. 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. The sulphate ingredient acts as a surfactant, essentially heavy duty soap that makes it easier to trap oil and grease.
Specialty shampoos are marketed to people with dandruff, color-treated hair, gluten or wheat allergies, an interest in using an organic product, and infants and young children ("baby shampoo" is less irritating).
Shampoo is a hair care product used for the removal of oils, dirt, skin cells, dandruff, environmental pollutants and other contaminants from the hair and scalp. Shampoo is typically applied to wet hair, worked into a lather and then rinsed out.
Shampoo is often followed by conditioner. shampoo is available in a wide variety of formulas with a broad range of functionality including zip zaps(for removing build-up), dandruff control, volumizing shampoo, deep cleansing shampoo and clarifying shampoo which can be used for treating oily scalp conditions.
There are also shampoos specifically for colored hair, permed hair and sensitive scalp. shampoo is generally made by combining a surfactant, most often sodium lauryl sulfate or sodium laureth sulfate withother ingredients such as water, fragrance, preservatives, methylchloroisothiazolinone, methylisothiazolinone, cationic surfactants and others.
