Opening a shampoo pump is a simple task that can be accomplished in a few easy steps. First, locate the small tab on the top of the pump. This tab is usually located near the spout of the pump. Once you have located the tab, press down on it and pull it towards you. This will release the lock on the pump and allow you to open it.
Once the pump is open, you can add shampoo to it. Be sure to not overfill the pump, as this can cause it to leak. Once you have added shampoo to the pump, close it by pushing down on the top of the pump until it clicks into place.
