If you visit your local pharmacy you are going to find there a wide range of shampoos. We decided to test if there are any specific differences between them and not just the price tag.
We first focused on comparing the pH of the shampoos.
Then we compared the flow properties.
After that we tested which shampoo makes the most lather.
Lastly, the grease-removing properties were compared.
In conclusion, we found out that the price of the shampoo didn't play a significant role on its properties.
