Shampoo is a hair care product used for the removal of oils, dirt, skin particles, dandruff, environmental pollutants and other contaminant particles that gradually build up in hair. The goal is to remove the unwanted build-up without stripping out so much sebum as to make hair unmanageable. On the outer layer of the hair, there will be the cover of the grease due to that dirt will stick it. Shampoo will remove the grease and along with it dirt will washed away.

Ideal properties Should remove the dirt easily To impart gloss to the hair Shall not dry the hair and should prevent from becoming brittle. Should provide nutrition required for the growth Should have curative effect for hair fall Easy distribution over the hair Good lathering power Easy to rinse and remove Give good luster to the hair Should leave easy to comb wet and dry hair Safe to use Should not make the hand and other parts of body rough and chapped Economic and eco friendly.

Shampoos have slightly acidic (pH less than 7), since a basic environment weakens the hair by breaking the disulfide bonds in hair keratin. Many shampoos are pearlescent. This effect is achieved by addition of tiny flakes of suitable materials, e.g. glycol distearate, chemically derived from stearic acid, which may have either animal or vegetable origins. Glycol distearate is a wax. Many shampoos also include silicone to provide conditioning benefits. Sodium Lauroamphoacetate is naturally derived from coconut oils and is used as a cleanser and counter-irritant. This is the ingredient that makes the product tear-free.

Polysorbate 20 is a mild surfactant that is used to solubilize fragrance oils and essential oils; meaning it causes liquid to spread across and penetrate the surface of a solid (i.e. your hair). Polysorbate 80 (or Glycol) is used to emulsify (or disperse) oils in water (so the oils don’t float on top)

Vitamins and amino acids The effectiveness of vitamins, amino acids and "pro-vitamins" to shampoo is also largely debatable. Proteins are unable to penetrate the skin or the hair, and even if they stick to the outside of the hair they will not help strengthen it. Amino acids cannot penetrate cells through the skin, either; they may be able to enter the dead strands, but without the complex protein-building machinery of the living cells they will not actually return damaged hair proteins to their undamaged state. Vitamins are essential for bio-processes that occur within the cell. They cannot have the same beneficial effects on dead tissues like grown hair. However, the physical properties of some vitamins (like vitamin E oil or panthenol) would have a temporary cosmetic effect on the hair shaft while not having any bioactivity.

Specialized shampoos Anti-Dandruff shampoos: These preparation contain fungicides such as ketoconazole, zinc pyrithione and selenium sulfide which reduce loose dander by killing Malassezia furfur. Coal tar and salicylate derivatives are often used as well.

Baby Shampoo They are less irritating and less prone to produce a stinging or burning sensation if it were to get into the eyes. For example, Johnson & Johnson's Baby Shampoo advertises under the premise of "No More Tears". This is accomplished by one or more of the following formulation strategies: Dilution, in case product comes in contact with eyes after running off the top of the head with minimal further dilution. Use of surfactants which, alone or in combination, are less irritating than those used in other shampoos. Use of nonionic surfactants of the form of polyethoxylated synthetic glycolipids and/or polyethoxylated synthetic monoglycerides, which counteract the eye sting of other surfactants.
