This study found that UVB radiation primarily causes hair protein loss, while UVA radiation mainly contributes to hair color changes, with no significant differences in mechanical properties observed between photooxidized and non-irradiated hair.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This review highlights that hair's chemical bonds, particularly disulfide bonds, are not homogeneous, as previously thought, but instead vary in response to different cosmetic treatments, suggesting a need for further exploration of ionic bonds and hydrophobic interactions.

This review discusses the pharmacological properties and physiological regulation of neuroactive steroids, focusing on their varied responses to stress and ethanol in rats, mice, and humans, but it reports no new findings.

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.
