A química e toxicidade dos corantes de cabelo

The market for hair dye involves a growing range of products, which requires greater understanding of hair properties, mechanisms of action and color development. In this work, we present a critical analysis of the classification, physical and chemical characteristics, chemical analysis and toxicological/mutagenic potential of dyes used in the hair dyeing process. A compilation of some studies was carried out, focusing on the available knowledge about these dyes and their effects on the environment and human health.
