If you’ve ever flipped over a box of hair dye and felt overwhelmed by the long list of complicated ingredients, you’re not alone. One of the most talked-about—and often misunderstood—ingredients in hair color is Para-phenylenediamine (PPD). It’s a common chemical in permanent dyes, but at Paradyes, we’ve made the conscious choice to leave it out of our formulas. Let’s dive into why.
What is PPD, and Why is it Used in Hair Color?
PPD is a synthetic chemical widely used in permanent hair dyes, especially for darker shades. It’s what helps the color penetrate deep into the hair shaft and stay put for weeks without fading. You’ll also find it in black henna tattoos, certain textiles, and even some makeup products.
Sounds great, right? Long-lasting, deep color—what’s the problem?
The Not-So-Pretty Side of PPD
While PPD does its job well, it comes with a big downside—it’s a known irritant and allergen. Many people who use PPD-based hair dyes experience reactions like:
✔️ Itchy scalp
✔️ Redness and swelling
✔️ Burning sensation
✔️ Severe allergic reactions in rare cases
For some, the reaction is immediate, while for others, repeated exposure can trigger PPD sensitivity over time. That means even if you’ve used PPD dyes before without an issue, your body might suddenly decide enough is enough.
Hairdressers and professionals who work with PPD-based dyes regularly are especially at risk, often developing skin irritation on their hands due to constant exposure.
And in rare cases? PPD reactions can be extreme, leading to anaphylaxis, a life-threatening allergic response.
That’s why every box of PPD dye urges users to do a patch test before application—it’s a serious risk.
What’s the Alternative?
Luckily, PPD isn’t the only way to get rich, vibrant hair color. Research has led to safer alternatives like Toluene-2,5-Diamine Sulfate (TDS), which provides similar results without the same high risk of allergies.
At Paradyes, we’ve made the switch to PPD-free formulations, using TDS instead to deliver gorgeous, long-lasting shades with a much lower chance of irritation.
Why Paradyes is Proudly PPD-Free
Your safety and comfort matter to us. That’s why all Paradyes hair colors are 100% PPD-free—so you can enjoy bold, vibrant hair without worrying about harsh chemicals.
That being said, everyone's skin is different, so we still recommend doing a patch test before using any hair dye—better safe than sorry!
The Bottom Line
PPD is effective, but it’s not risk-free. Many brands continue to use it, but at Paradyes, we believe beautiful hair color shouldn’t come at the cost of your skin’s health. Our PPD-free range lets you experiment with color fearlessly.
