1. What is product shelf life & storage?

An expired or improperly stored salon product is both a safety hazard and a regulatory non-compliance^[1]. The Period After Opening (PAO) symbol — an open jar icon with a number — indicates months of safe use after first opening. In any country, the cosmetics regulator requires either a best-before date or PAO marking on all products^[2].

2. The minimum you must do
