• Question: Why is there always a little bit of shampoo/shower gel left in a bottle that doesn't come out even if you shake it a lot or leave it for a while?

      Because life is just like that 😆

      It’s down to the design of the bottle. The shampoo is so viscous and sticky that it would rather cling to the bottle than let go and let gravity take control.
