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

4. Dialogue
🦉 & 🐥 & 🐮 — Salon operator dialogue
🐥
Piyo: Poppo, what does the little open-jar symbol on products mean?
🦉
Poppo: That's the PAO — Period After Opening. '12M' means the product is safe for 12 months after you first open it. After that, preservatives degrade, bacteria colonise, and active ingredients lose potency. An expired hair dye doesn't just perform poorly — it may cause unpredictable reactions.
🐥
Piyo: Should salons track opening dates?
🦉
Poppo: Absolutely. Write the date you opened it on the container with a permanent marker. FIFO (First In, First Out) for stock rotation. Remove expired products from shelves immediately. It's basic inventory management that prevents safety incidents.
🐮
Mou: Strong, kind, beautiful — an expired product is a broken promise to your client.
