Introduction: In this lab, we tested for the concentration of proteins within different brands of shampoo that were made for different hair types. We also tested for the presence of lipids in the shampoo as well. Our four samples were Dove, Biologe, Suave, and Ion shampoos. Dove is known to be very moisturizing for hair, the Biologe was for repairing damaged hair, Ion was for color treated hair, and the suave was for normal hair. We chose to test for proteins because many shampoos claim to have proteins that help hair grow and be healthy. We wanted to know which of our brands held the best for that. We also tested for lipids, because many shampoos say that they contain vitamins. We thought that the vitamins would show up as fats if they were fat soluble vitamins. Our hypothesis is that there will be varying concentrations of proteins within the different shampoos. We also suspect that if there are any available lipids, they will be in very low concentrations, if they even show up present at all. Our predictions for the proteins were as follows: Dove with the most proteins because it has so many moisturizers, Biologe next because it is for damaged hair so it would need proteins to rebuild the hair, Ion third because it is to help keep color treated hair healthy, and Suave last because it is just meant to keep normal hair healthy. If the lipids were to show positive at all, they would rank as the following: Dove, Biologe, Suave, and Ion. The reason they are shown in this order is because each shampoo shows different amounts of vitamins within the formula. The significance of this study in relation to the larger scientific field is that it shows what things are good, in a respect that they work, and it shows what things are bad, in the respect that they do not work. Proteins in shampoo are a very helpful thing when it 2

comes to keeping hair healthy. As a general populous, we do a lot of damage to our hair. We have heat treatments, like blow dryers, curling irons, straightners, shiners, etc.
