Development and Evaluation of a Novel Fish-Derived Protein Peptide Conditioner Formulated with Pneumatophorus Japonicus Heads Peptides

This study introduces a novel hair conditioner formulated with peptides derived from Pneumatophorus japonicus heads, demonstrating significant improvements in damaged hair. The conditioner enhances hair's surface morphology, reduces fragmentation and roughness, and increases gloss and smoothness by penetrating the hair shaft and interacting with keratin. It increases total amino acid content by 4.98% and hydrophobic amino acid content by 2.67%, closely resembling virgin hair levels. The PHP conditioner outperforms a commercial wheat protein conditioner, effectively repairing hair and offering a sustainable, natural hair care solution.
