Describe how shampoo and water act together to cleanse the hair?

Answer 1

Both of the detergent molecules contain 2 ends, one end attracts water (the hydrophilic molecule) and the other end attracts grease (the hydrophobic molecule). These detergent molecules life the grease off the surface of the hair and suspend it in the water, this action is called the emulsion. Dirt is held by grease so when the grease is lifted the dirt becomes loosened and can be rinsed away with water. This leaves the hair clean and shiny. Therefore it is very important to use a good shampoo that contains a good wetting agent making the hair more manageable and shiny when dry.

Answer 2

Shampoo contains surfactants that help to lift dirt, oil, and other impurities from the hair strands. When shampoo is mixed with water, it creates a lather that effectively breaks down and removes these substances from the hair. The water helps to rinse away the shampoo and the dirt for a clean and refreshed hair.

Answer 3

Shampoo is a form of soap and as such, helps to dissolve oily or greasy materials. Water can then wash away the dissolved material, along with pretty much any other form of dirt in your hair.

Answer 4

Shampoo and water can be used to clean hair. This is because the bubbles in the soap trap the dirt and oil and the water rinses it off the hair.
