May 2026 in “Zenodo (CERN European Organization for Nuclear Research)” The document reviews the development and evaluation of natural hair dye formulations, highlighting the growing interest in plant-derived pigments like henna, indigo, and beetroot as safer alternatives to synthetic dyes. These natural dyes primarily coat the hair surface and are associated with fewer health risks, showing low irritation potential in studies. However, they face challenges such as limited shade range, application consistency, and fading with washing. Some commercial products may be adulterated with synthetic additives, affecting safety perceptions. The review emphasizes the need for further research on standardization and improving the performance and acceptance of natural hair dyes.
May 2026 in “Zenodo (CERN European Organization for Nuclear Research)” The document reviews the development and evaluation of natural hair dye formulations, highlighting the growing interest in plant-derived pigments like henna, indigo, and beetroot as safer alternatives to synthetic dyes. These natural dyes primarily coat the hair surface and are associated with fewer health risks, showing near-neutral pH, low irritation potential, and good stability. However, they face challenges such as limited shade range, application consistency, and fading with washing. Some commercial products may be adulterated with synthetic additives, affecting safety perceptions. The review emphasizes the need for further research on standardization and improved delivery systems for better consumer acceptance.
