Abstract

Abstract : Background: Hair dyeing is very common and may cause allergic contact dermatitis. Oxidative (often termed permanent or semi‐permanent) hair dye products have constituted the focus of market surveys and toxicological risk assessments, while non‐oxidative (semi‐permanent, temporary or direct) products have not been assessed. Objectives: To identify the hair dye substances presently used in non‐oxidative hair dye products in Europe. Methods: Ingredient label data on eligible products in 5 European countries were collected, and 289 different non‐oxidative hair dye products were included in this study. Results: Up to 9 hair dye substances were present in each product. Sixty‐eight individual hair dye substances were identified on the 289 product labels, and their occurrence ranged from 0.3% to 34%. There were differences concerning substances used and their number per product between products of different consistency and colour. Conclusions: The hair dye substances in non‐oxidative hair dye products are different from those in oxidative hair dye products, and are currently not covered by patch test series. The toxicological and skin‐sensitizing profile of the substances in non‐oxidative hair dye products, as well as their concentrations, should be further investigated.
