This study observed that mercury-lamp irradiation may cause cleavage of disulfide bonds in keratins of white hair, leading to the formation of thiols in laboratory settings.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

In this study, researchers identified a three-step process underlying age-related curved hair from cyclical extension: surface lipid transfer, specific disulfide bond cleavage, and unraveling of α-helices into β-structures, which may inform care strategies to manage hair curvature.

This study found that 1,4-n-butylene dimaleate can restore the mechanical properties of reduced hair by reconnecting disulfide bonds and improving the hair's structural integrity using a thiol-Michael click reaction, compared to untreated reduced hair.

In this study, PEG and keratin scaffolds selectively influenced protein release rates based on charge and size, suggesting their potential for targeted delivery of protein therapeutics.
