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.
