This study introduced a novel graphene-based hair dye that is non-reactive, non-invasive, and eliminates toxic chemicals, while providing durable color, antistatic properties, and efficient heat dissipation, even after 30 washes.

This study found that hair treatments applied after chlorination, especially bleaching and dyeing, more significantly altered surface properties and weight loss, while perming most strongly affected tensile properties.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This study developed a biocompatible hair-dyeing technology using a dark polyphenol complex, which demonstrated effective hair coating, improved mechanical strength, and strong antioxidant properties while maintaining high cell viability.
