Riboflavin-Sensitized Photo-Acceleration of Food-Grade Pigment Formation: Kinetic Insights, Mechanistic Analysis, and Application in Rapid Hair Coloration

This study found that genipin-based pigments, accelerated by riboflavin and blue-light photocatalysis, achieved commercial-level hair dye results with enhanced gloss and excellent color retention while reducing cuticle disruption, offering a potentially safer and faster alternative to traditional hair coloration methods.

In this study, a method using riboflavin phosphate, citric acid, and polyols successfully optimized protein cross-linking in hair of all colors through visible light-mediated photo-cross-linking, improving the mechanical properties and hair-setting effects without the influence of hair color.

This study found that a new eco-friendly hair crosslinking method using visible light and non-toxic chemicals caused less damage and improved mechanical properties compared to traditional thioglycolic acid treatment.

This study found that supplementing baby pigs with riboflavin relieved external symptoms of deficiency, but many internal issues persisted, possibly due to inadequate dosage or treatment duration.

In this study, researchers observed that blue LED irradiation enhanced cosmetic permeation, increased diameter, and improved resistance of hair fiber in Caucasian and Asian ethnic groups, whereas African hair showed less change.
