November 2025 in “Zenodo (CERN European Organization for Nuclear Research)” This study examined how different hair dye processes affect hair structure at a molecular level, finding that oxidative dyes increase keratin porosity more than non-oxidative dyes, and highlighted emerging technology aimed at reducing hair damage while preserving color quality.
November 2025 in “Zenodo (CERN European Organization for Nuclear Research)” In this study, researchers investigated how different hair dye processes affect hair structure, finding that oxidative dyes disrupt hair more than semi-permanent dyes, and emerging technologies could help maintain hair health while achieving desired color.
November 2025 in “International Journal of Science and Research Archive” This study reviews how different hair dyeing methods affect hair structure, showing oxidative dyes cause more structural damage than semi-permanent dyes, while new technologies aim to minimize harm while preserving color.
