For this dot point in Lifestyle Chem:

identify data sources, plan, choose equipment or resources for, and perform a first-hand investigation to test manufacturers’ claim(s) on a commercial product such as soap, shampoo or shower gel and use the available evidence to analyse the results and discuss the validity of the claim(s)

At our school, part of our assessment is a report on this. Does anyone have any good ideas to test? E.g. the 'detangling' ability of hairbrushes .... the only problem is it needs to be able to be measured easily - like it's hard to measure the 'shininess' of hair after you use 5 different types of conditioners.

Any input would be greatly appreciated!!
