PPD stands for Paraphenylenediamine and is a colourant often used in hair dye. Allergy to hair dye is often caused by the colourant PPD. In WECOLOUR hair dye, there is no PPD. However, we do think good coverage is very important and that is why we use TDS (toluene-2,5 diamine sulfate) instead of PPD. TDS is less harmful and tolerated better. But also TDS is a chemical colourant. That is why we also say 'as pure as possible'. Most people who are allergic to PPD do not have this reaction with TDS.
But please order a tester first to be sure. You will receive the colour cream and activator with detailed instructions.The allergy test costs € 5,00. With your personal coupon code that goes with the tester you can order any product* at our webshop with a discount of € 5,00.
