Daily salon product shelf life checklist

Expired products removed from shelves and disposed
Stock rotation: oldest first (FIFO)
Storage temperature within manufacturer spec
Batch numbers recorded for traceability
Opened product log updated with today’s date
Returned or damaged products quarantined

5. Common mistakes to avoid

PAO symbol on products not tracked after opening
Expired products on shelves used 'until finished'
No FIFO rotation — oldest stock buried behind new

6. 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.
