What Does PPD-Free Hair Colour Actually Mean?
If you've ever experienced an itchy, irritated scalp after a colour appointment, PPD might be the reason. It's one of the most common causes of hair dye allergic reactions, and increasingly, people are seeking out PPD-free colour as a safer alternative. Here's what it actually means, and why it's worth understanding before your next colour appointment.
What Is PPD?
PPD, short for paraphenylenediamine, is a chemical compound that has been widely used in permanent hair dyes for decades. It's effective at producing rich, long-lasting colour — which is exactly why it became an industry standard. The problem is that PPD is also a well-documented skin sensitiser, meaning repeated exposure can trigger allergic reactions in some people, sometimes after years of using it without issue.
What Does a PPD Reaction Look Like?
Reactions can range from mild scalp itching and redness to more significant swelling, blistering, or contact dermatitis around the hairline, ears, and neck. In rare but serious cases, reactions can be severe enough to require medical attention. Because sensitivity can develop over time, someone who has used PPD-containing dyes for years without a problem can suddenly develop a reaction.
Why Choose PPD-Free Colour
PPD-free colour formulations use alternative compounds that achieve similar depth and longevity of colour without the same allergy risk profile. For clients with known sensitivities, or simply those who prefer a more cautious approach to what's applied to their scalp, PPD-free colour offers genuine peace of mind without compromising on the final result.
Our Approach at Alex Royer Salon
All of our Keune Tinta and Semi colour ranges are PPD free. This isn't a premium add-on or a special request — it's simply the standard we work to for every client who comes through our doors. We also use the Keune So Pure range, which goes further again, being paraben free, sulfate free, cruelty free, and vegan friendly for clients who want that level of consideration extended to their take-home hair care as well.
A Patch Test Is Still Worth Doing
Even with PPD-free formulations, anyone with a history of skin sensitivity or allergic reactions should still consider a patch test before a full colour service, particularly if it's your first time at a new salon or trying a new product line. Our team is always happy to talk through this with you before booking.
