Allergic contact dermatitis to substitute hair dyes in a patient allergic to para-phenylenediamine: Pure henna, black tea and indigo powder.
We report a case of a 50-year-old lady with allergic contact dermatitis to para-phenylenediamine, who in her quest to find a substitute hair dye, subsequently reacted to a number of plant-based hair dyes, including pure henna, black tea and indigo powder respectively. While these substances all contain tannins, testing to possible constituents tannic acid and gallic acid was negative.
