Contact urticaria with systemic symptoms caused by bovine collagen in a hair conditioner.
A case of contact urticaria associated with a serous rhinitis, dyspnea, wheezing, and a dry cough appearing after the application of a hair conditioner on the scalp is reported. Prick test results with the conditioner diluted at 1/16 and 1/8 were strongly positive (+3), as well as a prick test (+3) with one component of the conditioner called "hydrolyzed proteins," which contained hydrolyzed bovine collagen and stearyl trimethylammonium chloride.
