Abstract
Henna is a product used to color hair, but also to design labile tattoos on the skin. Black henna is becoming more fashionable
and it results from a mixture with paraphenylenediamine (PPD). Contact eczema after applying black henna tattoo can lead to
active sensitization to PPD, which can provoke violent allergic reactions [1]. Local cutaneous signs decrease in a few days and
after healing of eczema, residual post inflammatory hyperpigmentation may last for few weeks. We report a new case of a
black henna contact eczema.
