William Golding's Lord Of The Flies is not just an adventure story about a group of boys stranded on a desert island. It is, in all actuality, a model for the complexities of human behavior. The implication, or the "moral of the story" so to speak is that the absence of structure and discipline leads to pleasure, which in turn leads to anarchy, which is spawned from humankind's innate savagery. In other words, be a good citizen and follow the rules or deal with the consequences. Throughout the novel, the polar forces of good and evil are intricately woven between the characters, as well as within them. Ralph inherently represents goodness while Jack appears to be intrinsically evil. However this division not only manifests itself in struggles between the two boys and their respective followers, but also between the conflicting halves of their individual personalities.

Shampoo works by removing contaminants such as dirt that have built up over time. The soap bonds in the shampoo attach to the layer of protective oil on each strand, and when the shampoo is rinsed off, all of the dirt, dust and contaminants wash off as well. The active ingredient in all shampoos is a surfactant, which is a type of detergent. The surfactant in shampoos strips the sebum, a type of natural hair oil and all the dirt and foreign substances attached to it from the hair shaft temporarily. A thorough cleansing leaves hair clean and refreshed for a few days. Some people with more oily hair find that they need to wash their hair more often than people with naturally dry hair.
