March 2017 in “Asian Journal of Beauty and Cosmetology” This study found that caffeic acid reduced UVB-induced damage and oxidative stress in human dermal papilla cells, suggesting its protective efficacy against such cellular damage.
December 2025 in “Biomedicine & Pharmacotherapy” This study found that Melamax®, originally developed as an eco-friendly hair dye, provides significant protection against ultraviolet-induced oxidative and inflammatory damage in keratinocytes by modulating gene expression and signaling pathways, highlighting its dual potential for cosmetic coloration and skin photoprotection.
May 2026 in “International Journal of Cosmetic Science” This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.
