The study explores the use of riboflavin under blue-light irradiation to accelerate the formation of food-grade pigments for hair coloration. The process reduces reaction time by about 80% and results in pigments that provide commercial-level pigmentation with enhanced gloss, reduced cuticle disruption, and strong dye adhesion. The color remains vibrant even after 10 and 20 washes, showing no significant fading. This method offers a faster and potentially safer alternative to traditional hair-coloration techniques, maintaining color strength and durability while minimizing damage to hair cuticles.
