In my science fair project I will be testing different kinds of dry shampoos ranging in different price ranges from cheap to expensive. I will be finding the best dry shampoo to use whether its cheap or expensive.
You chose a fun and practical question to investigate, and you did a great job comparing the two products in a clear and organized way. Your experiment was easy to follow, and you explained your results thoughtfully, especially how the expensive dry shampoo performed better overall. I really like that you also reflected on how you could improve the experiment in the future. Great work applying science to a real‑life everyday product!
