1. A method for storing, mixing, and applying a solution having a first component and a second component which inhibits exposure of the first and second components to air and moisture until just prior to application, said method comprising:
hermetically sealing the first component within a first at least one ampoule;
hermetically sealing the second component within a second at least one ampoule;
disposing the first at least one ampoule and the second at least one ampoule within a hollow body, the hollow body having:
a head for dispersion of the solution;
a first breaking mechanism having a projection extendable into an interior of the hollow body; and
a second breaking mechanism, the first breaking mechanism and the second breaking mechanism disposed on a side of the hollow body, the first breaking mechanism aligned with the second breaking mechanism;
activating the first breaking mechanism such that the projection applies a force to break the first at least one ampoule and the second breaking mechanism to break the second at least one ampoule and release the first and second components from the first at least one ampoule and the second at least one ampoule; and
topically applying the solution having the first and second components through the head.
