I tested what kind of dry shampoo works best. I recognized there are many types to investigate. Overall, Trader Joes brand worked best. This is an important project because consumers deserve the best if they are spending their hard earned money on it. Keywords: dry shampoo, consumers
Well done, a very nice project!
This is a very interesting project that tests a product many people use every day. I liked that you compared different types of dry shampoo and also included a natural alternative like cornstarch. Your use of a scale to measure oil absorption helped make the experiment more scientific. Great job exploring a real-world problem!
