April 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This study found that cationic surfactant-based conditioning systems significantly improve hair combability by forming a stable low-friction film on hair surfaces, reducing friction and enhancing sensory performance compared to standard systems, as confirmed by both instrumental and sensory evaluations.
April 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This study found that cationic surfactant-based conditioning systems significantly reduce friction on hair fibers, improving wet and dry combability by forming a stable film layer on the hair’s surface, as verified by both instrumental and sensory evaluations.
February 2023 in “Biophysical Journal” Light can be used to stimulate ear hair cells, improving speed and consistency over previous methods.
