To properly dispense the desired amount of foam in your hand, you need to press slowly, more or less on the dispenser to control the flow of product. Slightly press the top of the dispenser, and it will dispense the foam slowly. It will allow you to get a "walnut" size amount. The more you press, the faster it goes.
