So, why are people paying attention to PPDs now? 


Well, simply, because they can be an allergen. To summarize, mild reactions include itching and contact dermatitis. More severe reactions can be dermatitis to the upper eyelids, rims of the ears, and swelling of the scalp and face. In the rarest and severe cases, anaphylaxis occurs. It’s important to note that PPD allergies can come out of nowhere. 


In fact, you’ve probably heard in beauty school the steps to take in terms of dealing with PPD. Always perform a patch test on your clients to determine if they have the allergy. 


Like we talked about before, clients have now, more than ever, knowledge about product and method disputes in the industry. For instance, a client comes in, geared up with questions about PPDs. Can you consult them? What do you say? It’s your responsibility to adhere to their concerns and make them feel comfortable and safe in your salon with you behind their chair.

It’s easy to think about PPDs like peanuts. Peanuts are safe unless you have a peanut allergy. Similarly, with PPDS, it’s the same thing. Even so, it’s subjective to each unique client. Undoubtedly, there’s no way to avoid it. 


Nonetheless, if your client happens to be allergic to PPDs, you need to be realistic and ready with options in mind to replace that ingredient.  PPD-free permanent colors do exist and are up-and-coming with many mainstream color lines. Subsequently, it’s still going to struggle to get the depth of pigment for gray coverage. So, always do your research.


With this mind, those that have an allergy need to figure out what to do, such as:


  • Stop using oxidative permanent artificial hair color
  • Try a PPD-Free hair color
  • Try a semi-permanent or a PPD-Free Demi-Permanent
  • Stop coloring hair all together
