Research explores coconut husk as a natural alternative for hair dye, highlighting its potential and effectiveness.
The increasing awareness of health hazards and environmental impact caused by synthetic hair dyes has sparked interest in natural alternatives. This study explores the potential of coconut husk—an underutilized agricultural byproduct—as a source of eco-friendly hair dye. Pigments were extracted from coconut husk using various solvents (water, ethanol, and alkaline solutions) and characterized using UV-Vis and FTIR spectroscopy. The extract was applied to human hair samples to evaluate dyeing potential, retention, and fastness. Results indicated that coconut husk contains tannins and phenolic compounds capable of imparting brown to reddish hues to hair. The study supports the development of a sustainable, cost-effective, and non-toxic hair dye formulation from agricultural waste.
