A dispensing device for dispensing a product includes a first chamber configured to initially contain at least one of a first composition and a mixture of the first composition and a second composition, a second chamber configured to contain the second composition, a flow passage for providing flow of the second composition from the second chamber to the first chamber, a selective air intake mechanism configured to selectively be placed in an open position to allow air to flow into the first chamber and a closed position to prevent air from flowing into the first chamber via the selective air intake mechanism, and an actuator configured to be actuated to cause an amount of a product to be dispensed from the first chamber. The product dispensed includes at least one of the first composition, the second composition, and the mixture of the first composition and the second composition. The device is configured such that in response to the product being dispensed from the first chamber, an amount of the second composition flows from the second chamber to the first chamber via the flow passage when the selective air flow mechanism is in the closed position.
