Notice Regarding a Conference Presentation on the Discovery of the “Glycoxidation Phenomenon in Hair”

COTA presented at an academic conference its joint research with Doshisha University on a new hair-damage phenomenon called “glycoxidation” and ingredients that suppress it. The research confirmed that AGEs-like substances increase in hair exposed to ultraviolet light after bleaching, causing the hair to become stiff, and identified a suppressive effect in 4 types of plant extracts.
