June 2023 in “Journal of applied crystallography” This study utilized the DNP–SANS technique on human hair for the first time and found significant changes in the SANS profile dependent on polarization conditions, providing insights into the structural composition and dynamic properties of keratin and its associated proteins.
March 2005 in “Journal of the American Academy of Dermatology” This study found that reintroducing certain depleted amino acids into weathered hair using cosmetic treatments can strengthen the hair, improving its look and feel and reducing damage and breakage.
