What Is PPD in Hair Color?

“PPD” stands for para-Phenylenediamine, or sometimes just called p-Phenylenediamine.

That’s great, but what does that mean? Well, PPD is a chemical, commonly used as a permanent hair color due to the ability to produce natural results. It darkens when oxidized.

The downfall of using PPD is that it may cause severe allergic reactions in some individuals. Symptoms of contact dermatitis (the allergic reaction caused by PPD) include a flaky, itchy red rash on the face, eyelids, ears, or neck. Hair stylists are also at risk for developing dermatitis on their hands and arms when working with PPD.

Most people are probably not going to be affected by PPD, but to avoid a PPD reaction, either use PPD-free hair color, or try doing a “patch test” before using the color.

My overall conclusion is that it’s probably best to avoid PPD, especially if you are prone to allergies. You can always do a patch-test of your hair color ahead of time. Just apply a small amount of hair color to the skin behind your ear and let it process for 45 minutes. If there is no reaction to the color, you will probably be okay.
