4. Template / checklist

Daily salon patch testing checklist

Patch test scheduled 48h before colour appointment
Inner elbow or post-auricular site cleaned
Correct product (same batch) applied in small amount
Client given written aftercare instructions
48h follow-up appointment confirmed
Positive/negative result recorded in client file
Client informed of re-test requirement if product changes

5. Common mistakes to avoid

48-hour wait seen as revenue loss — clients booked for same-day colour
Test site (post-auricular) not standardised across staff
Positive patch test result not recorded in permanent client file

6. Dialogue

🦉 & 🐥 & 🐮 — Salon operator dialogue

🐥

Piyo: Poppo, why is 48 hours the standard wait time for a patch test?

🦉

Poppo: Type IV delayed hypersensitivity — the immune response to hair dye allergens like PPD — peaks at 48–72 hours. A test read at 24 hours misses most positive reactions. That's why the 48-hour minimum is non-negotiable, and the EU ALG regulation reinforces this.

🐥

Piyo: Can a client sign a waiver to skip the patch test?

🦉

Poppo: A waiver doesn't protect you. If a client suffers anaphylaxis from a product you applied without testing, 'they signed a waiver' is not a legal defence in most jurisdictions. The duty of care rests with the professional providing the service.

🐮

Mou: Strong, kind, beautiful — 48 hours of patience prevents a lifetime of regret.
