March 2026 in “INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT” This study suggests that herbal hair dyes, using natural pigments, may provide a safer, eco-friendly alternative to traditional synthetic dyes, although their effectiveness depends on application technique and botanical purity.
This study developed a natural herbal hair dye powder using Eclipta prostrata, Nigella sativa, and Aloe Vera, which offers safe and environmentally friendly hair coloring while avoiding harmful effects associated with conventional dyes.
This study evaluated various herbal blends of powdered leaves, including Henna and Indigo, for their coloring and sensitivity reactions, finding Henna and Indigo to be effective natural colorants for achieving a reddish-brown hair color with better retention than marketed herbal hair dyes.
November 2025 in “Journal of Ayurveda and Integrated Medical Sciences” This study evaluated an herbal hair dye made from plant-based ingredients, finding it stable, non-toxic, and effective in providing lasting color, improving hair texture, and reducing hair fall, making it a viable and eco-friendly alternative to chemical dyes.
August 2022 in “Zenodo (CERN European Organization for Nuclear Research)” This study evaluated various herbal combinations for hair coloring and found that a formulation of Henna and Indigo provided a natural reddish-brown color with better retention compared to marketed herbal hair dyes, without using synthetic agents that can cause allergic reactions.
