I know soap and detergents are different; so what is shampoo?

I don't really understand soap and detergent, either, except someone said detergent has a molecule that holds grease at one end and water at the other, thereby breaking up grease. So is shampoo a separate category, or what?I know soap and detergents are different; so what is shampoo?

Everyone is quoting Wikipedia. Here is my quick take without looking at wiki. They are all basically the same thing, but slightly different. You can use bar soap to wash your hair, hands, and dishes etc. It just won't work too well. Plus, it probably would work better if you soak the bar soap in water and make it liquidity.





You can also use shampoo %26amp; detergent to wash your hands. I have used detergent to wash my hands all the time except the stronger ones (like bleach, hehe)

From ancient times to this day, Indians have been using different formulations of shampoos using herbs like neem, shikakai or soapnut, henna, bael, brahmi, fenugreek, buttermilk, amla, aloe, and almond in combination with some aromatic components like sandalwood, jasmine, turmeric, rose, and musk.

Shampoo is a common hair care product used for the removal of oils, dirt, skin particles, dandruff, environmental pollutants and other contaminant particles that gradually build up in hair. The goal is to remove the unwanted build-up without stripping out so much as to make hair unmanageable.





Shampoo, when lathered with water, is a surfactant, which, while cleaning the hair and scalp, can remove the natural oils (sebum) which lubricate the hair shaft.





Shampooing is frequently followed by conditioners which increase the ease of combing and styling.








Many shampoos are pearlescent. This effect is achieved by addition of tiny flakes of suitable materials, eg. glycol distearate, chemically derived from stearic acid, which may have either animal or vegetable origins. Glycol distearate is a wax.
