Explain why hair conditioners contain surfactants which give the hair surface a waxy, shiny apperance?
Answer:
Actually, the surfactants are used to make insoluble materials go into the solution in the shampoo formulation and provide the soaps or detergents (yuk!) that remove the excess oil and the dirt that adheres to that oil by now making that oil water soluble. In essence they (surfactants, soaps, detergents) make water "a wetter thing" so they remove the insoluble things that make your hair oily and dirty. The wax like materials that make hair shiny and basically glue the split ends together are just one of the materials that the surfactants help to put into solution.
