This study found that alopecia areata patients with a CCHCR1 gene variant had higher recurrence rates and structural abnormalities in hair compared to those without the variant.

This review summarizes recent advances in understanding intermediate filament structure and their implications for pathological mutations and human diseases, but it reports no new experimental results.

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.

In this study, mouse sweat gland development relied on a regulatory sequence initiated by Wnt/β-catenin signaling, and disruptions in Wnt, Eda, or Shh pathways led to distinct developmental failures.

This study developed a multiscale model to understand human hair fiber mechanics and found that the yield stress decreases linearly with temperature, supported by both simulations and experimental stretching of hair fibers.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

In this study, molecular dynamics simulations indicated that the Glu413Lys mutation in human hair keratin significantly affects the stability of coiled coil structures, whereas Glu413Asp showed no impact on stability.

This study found that hydrophobic amino acids from egg white hydrolyzed protein and L-phenylalanine effectively penetrate deep into the human hair fiber, increasing specific contents in both virgin and bleached hair.

This case report describes a 4-year-old boy with Penile Hair Tourniquet Syndrome caused by a hair coil, highlighting the importance of early diagnosis in circumcised boys to prevent severe complications.

This case report describes an 8-year-old child with penile tourniquet syndrome due to a constricting thread, which led to partial distal penile amputation and required surgical intervention.

Human hair keratin has a 40% α-helix structure that changes to a random coil in 8 M urea.

In this study, CD44 expression was absent in alopecia areata-affected scalp, with some patients regaining expression after treatment despite no significant hair regrowth, suggesting involvement in the disease's pathogenesis.

This study found that permanent wave treatment accelerates hair degradation after protease exposure, showing significant morphological differences compared to untreated hair and linked to damage from Alpha-helical region denaturation.

In this study, reducing agents like ammonium thioglycolate, L-cysteine, and sodium sulfite in shampoo effectively decreased hair flyaway and frizz without causing damage, as no critical hair damage was observed in structural and tensile strength assessments.

In this study, researchers developed enzymatic methods to isolate hair cuticle cells and remove the hair cuticle layer, finding that the harvested cuticle cells are thermally more stable and contain different structural proteins compared to descaled hair fibers.

This case report describes successful gradual improvement of Fox-Fordyce disease symptoms in a 22-year-old woman treated with oral teicoplanin and topical creams.

This study found that premature desquamation of the inner root sheath is a non-specific histologic feature in scarring alopecia and cannot be used alone to define central centrifugal cicatricial alopecia.

This study observed that inflammatory AIGA is associated with sweat duct inflammation and sweat coil atrophy, while non-inflammatory AIGA involves only sweat coil atrophy, suggesting distinct pathological features between the two.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This case report highlights an 11-month-old boy with near total amputation of the glans penis due to Penile Hair Tourniquet Syndrome, who underwent successful two-stage surgical repair for a satisfactory outcome.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

In this study, chemical treatments during permanent hair straightening were found to randomize proteins in the cortex, aiding in the reconnection of disulfide bonds during oxidation.

This study presents the first detailed 3D models of the complete K1/K10 keratin dimer and identifies structural features and interactions that may inform understanding of keratin filament assembly.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

This study found that non-toxic polycarboxylic acids can achieve satisfactory hair perming effects with limited strength loss, suggesting they have potential as a safer alternative to harmful perming chemicals.

In this study, the researchers identified a variant in the CCHCR1 gene associated with an alopecia areata subtype characterized by impaired keratinization and autoimmune events.

This study utilized the DNP–SANS technique on human hair for the first time and found significant changes in the SANS profile dependent on polarization conditions, providing insights into the structural composition and dynamic properties of keratin and its associated proteins.

This study demonstrated that imidazole-based ionic liquids, particularly [Emim]DEP, effectively dissolved yak hair keratin, maintaining its structure better than other tested solvents, and also performed well on human hair and goat wool, with consistent performance even after five recycling cycles.

This abstract appears to consist entirely of repeated color specifications and logo guidelines, providing no research findings or new results.

This study examined three olive oil formulations of baricitinib for topical delivery in treating alopecia areata, finding that Oil A showed the highest skin retention and maintained skin integrity without irritation, suggesting its potential for further investigation.
