Dialogue

🦉 & 🐥 & 🐮 — Salon operator dialogue

🐥
Piyo: Poppo, are perm chemicals really that dangerous?
🦉
Poppo: Thioglycolate in perm solution is a strong reducing agent. Skin contact causes irritation, prolonged exposure can cause sensitisation, and ingestion is a medical emergency. The neutraliser (hydrogen peroxide) is an oxidiser. These are serious chemicals that happen to be used in a beauty context.
🐥
Piyo: What's the number one mistake salons make with perms?
🦉
Poppo: Not setting a timer. Over-processing isn't just bad for the hair — it means prolonged chemical exposure for both client and stylist. The SDS specifies exact processing times for a reason.
🐮
Mou: Strong, kind, beautiful — a beautiful perm starts with respecting the chemistry that makes it possible.
