Allergy Awareness Week 2026: Your Salon's Essential Guide to Client Safety
Date Published
Every week in the UK, salons perform hundreds of thousands of colour services — and behind every one of them is a duty of care that can't be shortcut. Allergic reactions to hair colour ingredients, particularly paraphenylenediamine (PPD), are on the rise, and they don't always come from new clients. A loyal regular of ten years can suddenly develop a sensitivity, sometimes with serious consequences.
With Allergy Awareness Week running from 20-26 April, now is the perfect moment to revisit your salon's allergy protocols, refresh your team's training, and show your clients that their safety is every bit as important as the finish on their blowout.
Why this matters more than ever
The number of contact allergies linked to hair colour has grown steadily over the past decade. Clients are exposed to PPD, fragrances and preservatives not just through salon services but through home-use products, tattoos, and even some textiles, meaning the "first reaction" can happen during a routine salon visit without warning.
The legal picture has sharpened too. Salon owners in the UK have a clear duty under consumer safety legislation and insurance terms to carry out manufacturer-recommended patch testing. Skipping a test, even at the client's insistence, can put your insurance, your reputation and, most importantly, your client at risk.
Patch testing: beyond the box-tick
Too many salons still treat patch testing as an administrative hurdle. In reality, it's one of the most important conversations you'll have with your client.
Keep a clear, dated record: Every test should be logged with the date, product and outcome. A quick digital system, even a simple spreadsheet, is invaluable if a question ever arises.
Test before every new formula: If you switch brand, line, or shade family, a fresh patch test is essential. Reassure clients this isn't a formality; it's a sign you take their care seriously.
Communicate with warmth, not jargon: Explain that reactions can appear years into a client relationship. Most clients appreciate the honesty, and it strengthens trust.
Get your team speaking the same language
Consistency is where most salons slip up. One stylist patch tests religiously, another forgets, and suddenly your policy is only as strong as your most rushed colourist on a Saturday afternoon.
Use Allergy Awareness Week as an opportunity to hold a short team huddle. Walk through your patch-testing protocol together, talk about how to spot early signs of a reaction (redness, itching, burning, swelling), and agree on what to do if a client presents a concern mid-service. Everyone on the front desk should know the script too — they're often the first point of contact when someone calls with a reaction.
Free education to mark the week
There's genuinely useful support available right now. TrichoCare Education, together with Colourstart, is offering £10,000 worth of free online allergy awareness courses throughout the week. The flexible one-hour course covers immune system function, the science behind allergic reactions, and the key ingredients, including PPD, that every colourist should understand. It's designed for busy salon professionals, so you can work through it between clients or as a team on a quieter morning.
If your team hasn't had fresh allergy training in the past twelve months, this is a brilliant, zero-cost opportunity to bring everyone up to date.
Make it visible to clients
Confidence is contagious. Consider updating your consultation forms, booking emails and social channels this week with a short message about your patch-testing policy. Something as simple as, "We patch test 48 hours before every colour service, because your safety is part of the experience," goes a long way.
A short post on your Instagram explaining what a patch test actually is (many clients are still unsure) doubles as useful content and demonstrates your professionalism.
The bigger picture
Great salons aren't just defined by what they create; they're defined by how they care. Allergy Awareness Week is a reminder that the small, unglamorous systems behind the chair, the patch tests, the notes, the team briefings, are what make beautiful work sustainable.
Use the week to tighten your protocols, lean on the free training on offer, and have a confident conversation with your clients. Their trust is the foundation on which everything else is built on.
*It's worth noting that some modern "PPD-free" colours use PTD (Paratoluenediamine). While often better tolerated, PTD can still cause reactions in PPD-sensitised individuals due to cross-reactivity
