Hello! Thank you very much for your time to review our service and products. Every Day Shampoo bottle is larger and able to contain more than 200ml. As we state in our site, the shampoo contains 200ml but it may seem half full because it can be used by pharmacist for some other combintations. Because of that, we created bigger packaging. However, you received 200ml of the shampoo as promised. Kind regards, Frezyderm team.
