This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

This study suggests that increased amounts of less stable disulfide conformers in hair shafts may be linked to the brittleness observed in trichothiodystrophy.

In this study, researchers found that trichothiodystrophy hair brittleness is linked to abnormalities in sulfur content and structural organization, making it prone to breakage.

This study observed that bleaching brown human hair with persulfate salts and hydrogen peroxide induced significant conformational changes in keratin, particularly affecting disulfide bridges and oxidized sulfur species, which may inform the development of hair restorative treatments.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.
