Hint:Soaps are only soft water and on the other hand, detergents are soluble in both hard and soft water. Hard water contains salts or ions like calcium and magnesium in them and soft water is devoid of such ions.

For example: $2{{\text{C}}_{17}}{{\text{H}}_{35}}{\text{COONa}} + {\text{CaC}}{{\text{l}}_2} \to 2{\text{NaCl}} + {\left( {{{\text{C}}_{17}}{{\text{H}}_{35}}{\text{COO}}} \right)_2}{\text{Ca}}$ where ${\left( {{{\text{C}}_{17}}{{\text{H}}_{35}}{\text{COO}}} \right)_2}{\text{Ca}}$ is insoluble calcium stearate. These insoluble soaps separate as scum in water and are useless as cleansing agents, in fact, these are a hindrance to good washing, mass. Hair washed with hard water looks dull because of this sticky precipitate. Dyes does not absorb evenly on cloth washed with soap using hard water, because of this gummy mass.
