Effects of chemical structures of polycarboxylic acids on molecular and performance manipulation of hair keratin

The study developed a non-toxic hair crosslinking formula using polycarboxylic acids, which demonstrated high treatment performance and mechanical retention. This formula aimed to manipulate hair keratin at the molecular level, enhancing the structural integrity and durability of hair. The research focused on the chemical structures of polycarboxylic acids and their effects on hair, providing insights into improving hair treatment formulations.
