This review re-examines hair blowouts as a material science process, where water acts as a plasticizer altering keratin's glass-transition temperature, allowing for temporary hair shaping through a moisture-induced matrix state change under heat and tension.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.

This article discusses a hypothetical model of androgenic hair trichophore composed of various chemical components, but it reports no new empirical findings; the authors emphasize the model's potential impact on hair cosmetics.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

In this study, certain cysteine residues in Romney sheep wool fibers were labeled more often during stretching tests, particularly under wet conditions, suggesting variability in their disulfide bond contributions to fiber mechanics depending on hydration.

This study found that zinc is primarily located in the tails of mature rat sperm, associated with -S-S-bonded structures, and suggests a possible similarity in zinc interactions between sperm keratin and hair proteins.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This study's simulations suggest that replenishing free 18‐MEA could restore damaged hair surface properties, highlighting the importance of optimal fatty acid spacing for maintaining hair integrity.

This study mapped potential targets and pathways for baicalin's action in androgenic alopecia, suggesting it may inhibit 5α-reductase and serve as an effective treatment ingredient.

This review examines the science and technology behind temporary and permanent hair straightening, discussing the processes, potential advancements, and considerations for reducing adverse effects, but does not report new research findings.

This study found that treating hair with aqueous KCN converts disulfide bonds to monosulfide crosslinks, affecting the elasticity and crosslink distribution in hair microstructures.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

This study reports that the dye peri-xanthenoxanthene (PXX) can act as an efficient photocatalyst for various radical reactions, including complex dual catalytic processes and the synthesis of an investigational drug intermediate.

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 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.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.
