4. 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.
