Chapter 1. Introduction
1.1Goal Statement
The challenge I’m facing is to find the answer on how to evaluate or measure the good cleansing ability of shampoo. I wash my hair every day in the morning, as I feel my hair is so oily and dirty and gives me uncomfortable feeling. I have to spend significant amount of time in the morning for hair washing followed by hair drying and I want to reduce my frequency of hair washing as other people do. My frequency of hair washing was suspected due to the used of poor shampoo cleansing ability and therefore I need to find and use the suitable one. In order to find shampoo with good cleansing performance I was deliberately watching shampoo advertisement on television, but unfortunately I could not find any advertised shampoo that claimed to have good cleansing ability. Shampoo advertised on television is simply claiming on its manageability/conditioning benefit, anti dandruff benefit or other non-cleansing benefits such as strong hair or less hair damage. On using mild shampoo which was claimed to be suitable for daily use, I found sometime my hair is still a bit oily after hair washing and therefore I keep experimenting to use different brands of shampoo to find the suitable one for me that is shampoo with a good cleansing ability.

This project is using 2 aims, which are measuring the foam volume of the marketed shampoos and to compare and evaluate the marketed shampoos on its ability to cleanse the hair. 1.2 Outlines
I include some important things in this report. Those important things are aims, hypothesis, variables, theory, procedure, data, analysis, discussion, conclusion, suggestion, bibliography and appendices. Aims are the goal and the objective. I’m doing this project by making a hypothesis which guides the development and proceeding of this project. Variables are mainly things that control my experiment, and there are 3 variables; dependent variable which is related to what we are going to measure, independent variable is the verities of this experiment, and control is things that are in charge in the experiment. Theory is the basic knowledge and will explain specifically about my topic and giving us background for the experiment. Procedure is the method of doing the experiment, it will be explained step-by-step. Analysis is the analyzed data that has been tested, the result have to be reviewed and evaluated one by one carefully and link well to the basic theory. Discussion will discuss about the relation between my hypothesis and the result, this is the point where I explain about the result, which will answer the goal of the experiment that has already been designed before. Suggestion is the part where I reflect on my experiment, I will talk about “what is not going so well”, “what are things need to be improved” and “things that can be done better next time”.

I will talk about my hypothesis here. Well, people use shampoo to wash the hair. Some people (including me) wash their hair every day, due to uncomfortable feeling on having dirty hair. Though there are plenty of marketed shampoo in supermarkets and some of them also heavily advertised, but the advertisement of the shampoos seem to focus on offering their non-cleansing benefit, such as free from dandruff (Clear), shiny hair (Sunsilk black), manageability benefit (Dove), and unfortunately no hair cleansing benefit is offered. The active ingredient in shampoo which can remove dirt from hair is the active detergent, and the active detergent is generating foam during hair washing. So, good cleansing ability of shampoo will be determined by the presence and concentration of active detergent in the shampoo, which will be related to the generation of the foam during hair washing. Therefore, foam volume measurement of shampoo will help people to select a suitable shampoo that has a good cleansing ability.

The variables are amount of tested shampoo brand (1 ml), amount of aqua (39 ml/trial)...
