Dialogue
🦉 & 🐥 & 🐮 — Salon operator dialogue
🐥
Piyo: Poppo, what exactly is the EU ALG regulation changing in July 2026?
🦉
Poppo: EU Regulation 2024/996 mandates individual labelling of 80 specific hair-dye allergens with concentration limits. Before this, products only had to carry a generic 'may cause allergic reaction' warning. Now each sensitising substance must be named on the label.
🐥
Piyo: So salons need to update their product inventory?
🦉
Poppo: Yes โ and their patch-test protocols. If a client is allergic to PTD specifically, you need to know which of your products contain PTD and at what concentration. The SDS is your friend.
🐮
Mou: Strong, kind, beautiful โ knowing exactly what's in your colour tube is the difference between art and risk.
