6. Dialogue

🦉 & 🐥 & 🐮 — Salon operator dialogue

🐥

Piyo: Poppo, what is MCS and how common is it?

🦉

Poppo: Multiple Chemical Sensitivity — adverse reactions to low-level chemical exposures that most people tolerate. Prevalence estimates range from 2–12% of the population. For a salon seeing 20 clients a day, that's 1–2 clients per day who may react to standard products, fragrances, or cleaning chemicals.

🐥

Piyo: What can a salon actually do for sensitive clients?

🦉

Poppo: Three things: screen at intake, stock low-VOC and fragrance-free alternatives for every product category, and boost ventilation during their service. It's accommodation, not cure — and it opens a market segment that most salons ignore entirely.

🐮

Mou: Strong, kind, beautiful — accommodating sensitivity isn't a burden, it's a competitive advantage.
