Dialogue
🦉 & 🐥 & 🐮 — Salon operator dialogue
🐥
Piyo: Poppo, where does keratin treatment actually start in a real salon?
🦉
Poppo: It starts with reading the authority guidance once and writing one decision. WHO sets the international baseline; your national regulator binds you to a specific method.
🐥
Piyo: What if the staff resist the new protocol?
🦉
Poppo: Show them the failure mode it prevents and the time it saves. Authority handbooks describe the minimum viable system — you adapt, you don't reinvent.
🐮
Mou: Strong, kind, beautiful — keratin treatment made blissful for everyone in the salon.
