Abstract
A shaving preparation that undergoes a change discernible to the user when the hair to be shaved has had time to absorb water and soften, when the shaving preparation has been sufficiently hydrated, after a period of time in which proper hair hydration would normally be expected to have been achieved, or any combinations thereof. Shaving preparations of this type advantageously alert the user when at least one desired shaving condition exists.
