This study conducted in situ tensile loading experiments with atomic force microscopy to observe how conditioning treatments affect the tensile response of virgin, chemically damaged, and mechanically damaged Caucasian hair.

This study found that the tensile strength of curly hair is influenced by two main components, with springiness (toe region) contributing significantly, unlike in noncurly hair where it is negligible.

This study found that keratin fibers like human hair undergo thermal and mechanical transitions that can help assess changes from cosmetic processes such as bleaching and perm-waving.

This study found that chronic stress may inhibit hair follicle growth and melanogenesis in mice through modulation of the central HPA axis, with C57BL/6 mice appearing most sensitive to these effects.

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.
