January 2026 in “Colloids and Surfaces B Biointerfaces” This study found that treating damaged hair with maleic-modified amino silicone oil created a highly hydrophobic surface, reducing water content and improving hair's mechanical properties and thermal stability.
This study found that a blend of low- and high-molecular weight hyaluronic acid significantly improved penetration into the hair cortex compared to individual HA types, reducing frizz and increasing hair elasticity and water content, as measured by Confocal Raman Spectroscopy.
October 2025 in “Clinical Cosmetic and Investigational Dermatology” This study found that hair treated with a supplemental hair care product showed significantly higher absorption, deeper penetration, and reduced dryness compared to untreated and water-treated hair, as measured with 3D Raman spectroscopy.
