Abstract:
Hair dye ingestion is an uncommon form of poisoning in the west, however, in some parts of the world such as East Africa and Indian Sub-continent it is not uncommon. The main component of hair dye causing toxicity is Paraphenylenediamine (PPD). This compound has been found to cause angioneurotic edema, rhabdomyolysis and renal failure. We present a case of hair dye poisoning who presented with respiratory distress due to laryngeal edema and later developed trismus and carpopedal spasm. This case report highlights the combined toxicities of sodium EDTA and PPD.

Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
