New to Keratin? There is a guide in the encyclopedia. Read the guide → Studysummary This study reported that a new coating made with delaminated Ti₃C₂ MXene nano-sheets and a tea-derived compound effectively protects hair keratin from damage by providing UV screening, thermal dissipation, and antioxidation, while also enhancing mechanical strength and restoring wettability. Our plain-language summary of this paper — not a Tressless recommendation.
The study presents a novel MXene-metal polyphenol network (MX-MPN) coating designed to enhance the protection and mechanical properties of keratin fibers in human hair. By combining Ti3C2 MXene sheets with a metal-polyphenol network derived from EGCG and multivalent metal cations, the coating aims to provide robust UV protection, increased tensile strength, and improved wettability for chemically damaged hair. Despite challenges in coating negatively charged hair surfaces, the MX-MPN composite demonstrated significant improvements in mechanical strength, UV resistance, and thermal conductivity, while maintaining color fastness and reducing static electricity. The coating also exhibited hydrophobic characteristics similar to healthy hair and retained its efficacy for at least 3 weeks with reduced cytotoxicity, offering a promising approach for semi-permanent hair treatment.
