Chemistry of Shampoos

An understanding of the chemical ingredients used in shampoos will help you prescribe the best product for your clients

Chemistry of Shampoos

• Water– The main ingredient

• Purified or deionized

– First ingredient usually on product labels because of largest % of remaining ingredients

Surfactant Molecule

• Surfactant & detergent are synonymous– Meaning cleansing or “surface active” agent

– Hydrophilic end• “head” end of a shampoo molecule & is water-attracting

– Lipophilic end• “tail” end of a shampoo molecule & is oil-attracting

Since both ends are working during a shampoo, a push-pull effect is created that causes the oils, dirt & deposits to form little balls that can be lifted off in the water & rinsed from the hair

Types of Shampoo

Shampoo products represent the highest dollar expenditure in hair care products

• Acid-balanced– pH the same as hair of 4.5 to 5.5– By adding citric, lactic or phosphoric acid to any shampoo , it

can become acid-balanced

Some believe that a pH of 4.5 to 5.5 is essential to prevent excessive dryness & hair damage. The Consumer’s Union chemists believe a pH between 5-8 is too small to affect the hair & scalp due to the limited time of actual application
