Abstract

Due to the unprecedented speed of the global population aging, there is a growing demand for hair dyeing. However, conventional chemical hair dyes are often not favored by individuals because of their harsh dyeing conditions and potential damage to humans and the environment. Recently, melanin-mimicking hair dyeing based on nanoscaled polydopamine (PDA) coating has received considerable attention from the scientific community. In this review, we presented a comprehensive summary of the use of PDA in the domain of hair dyeing. Its melanin-like structure and favorable properties for use as a potential hair dye are described in detail. The PDA dyeing systems based on chemical/enzymatic reactions were particularly highlighted, to provide practical guidance for the establishment or selection of the condition for PDA dyeing. In addition, the possible mechanisms behind the coating effect of PDA at the hair surface were fully discussed. Overall, this review provided an informative source for the development of PDA-based bio-inspired pigments as green alternatives for hair dyeing as well as other biological uses and would help the understanding of the interaction at the nano-bio interface.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
