Soap is made of long strands of carbon atoms. These atoms have open spaces due to their physical structure, Thus it allows the dirt and oils to latch on to them.. Then the water comes in and rinses them away, taking the dirt and oil with them.

Can water alone clean your hands?
Oils on human skin and hair keep them from drying out, but the oils can also attract and hold dirt. The oily dirt is a nonpolar mixture. So washing with water alone wont clean any of the dirt away. So that's where soap comes in! Soaps are salts of fatty acids, which are hydrogen molecules with carboxylic acids at one end...------ Soap has a ionic end that will dissolve in water a longg hydrocarbon portion that WILL dissolve in oily dirt. The dirt is removed from your skin and hair or fabric, suspended in the wash water and washed away:)
Why does soap and water remove dirt?
soap lowers the surface tensions of water, making water wetter and more able to remove soil and dirt.
Which part of a soap is responsible for its ability to dissolve fats and oily dirt?

When you do laundry what cause the nonpolar oil or greasy dirt to mix with the polar water?
Most laundry dirt is oily or greasy. Detergents can mix with both oil and water, so when the wash water goes down the drain, the soap and dirt go with it. Detergent molecules are designed with a polar head of the molecule and a non-polar tail. The detergent molecule thus "ties together" the water and the grease. Soap performs the same function.

Why is water alonE nOt sufficient for RemoviNG oily dirt?
Oil is a lipid that is hydrophobic (water does not interact with it) and will form a perfect barrier between aqueous compartments; causing the oil to float on top of the water, which will spread the oil around when trying to clean it up.

How does water and shampoo act together to cleanse hair?
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.shampoo is a chemical that is attracted to grease and oil, when you shampoo your hair the shampoo is attracted to the grease, as you stimulate your scalp you activate your sweat glands and this removes the grease/oil from your hair during the reaction between the shampoo and water. however if you over activate your sweat gland this reaction can cause your hair to become more greasy/oily... not only does this remove grease and oil it removes other substances and dirt by using different shampoos and conditioners.
If you mix the dirt in water and just let it sit will all the dirt go to the bottom?
Dirt is denser than water, so it will eventually settle to the bottom, but that would take a VERY long time. ---- This depends on the dirt. If say the Dirt containe some salt, then the salt will dissolve in the water and not sink down. It is watersoluble. Some components might be heavyer than water, and will obviously sink to the bottom. If the dirt contain some oily substances, then these substances will float on top. Dirt is not a simple compound that is the same all over the world. Dirt is chemistry at a quite high level :-) Regards. Also, very very small particles will form a colloid and not sink. It's like milk, which is mainly a colloid, not a solution.
