What are PPDs?
They are p-phenylenediamines found in ALL permanent and some semi permanent hair colorants with the exclusion of certain hennas. They add colour to the hair but are severe skin irritants and in rare cases can provoke severe or extreme reactions. A PPD reaction would typically result in skin swelling, burning and blistering in the region where they are applied. Naturtint Permanent Hair Colorant contains minimum levels of PPD whilst Naturtint Reflex Shine on Color Rinse is free of PPDs.
