Abstract

Para-phenylendiamine (PPD) from hair dyes is known to be a potent skin sensitizer and it is responsible for most of the complications reported after the application of black henna dyes, which include contact dermatitis, scars, and temporary or permanent dyspigmentation. Less commonly, type 1 hypersensitivity reactions such as urticaria, angioedema, or anaphylaxis have been reported [1]. We present a case of allergic contact dermatitis with massive facial swelling owing to hair coloring with PPD
