This study describes a case of generalized trichorrhexis nodosa and finds that defects in alpha-keratin chain formation and low cystine levels in hair may contribute to the condition.

Spontaneous keloids may be linked to nephrogenic systemic fibrosis in dialysis patients.

In this study, variation in the KRTAP15-1 gene in goats was linked to changes in cashmere fibre diameter, with specific variants showing dominant or recessive effects.

This review discusses hair tourniquet syndrome, highlighting its potential for delayed diagnosis and the association with maternal telogen effluvium, but reports no new clinical results.

This study observed that congenital hypotrichosis in crossbred cattle is linked to short, curly, dilute-color hair, potentially due to color dilution mutants in European breeds.

This study argues that the reported "toughening" transition in keratin is a misinterpretation, actually representing the evaporation peak of residual water in the fibers.

This study suggests that the C-terminal of AHF is crucial for its binding to keratin bundles and modulating the keratin meshwork in hair follicles.

This review discusses the use of ceramic-coated flat irons for hair straightening and reports no clinical results; the authors highlight potential hair damage risks from improper use.

This study found that the extraction-resistant structures in hair, feathers, and hagfish teeth are due to ε-(γ-glutamyl)lysine cross-linked proteins, emphasizing their role in maintaining the integrity of these materials.

This study reports new monilethrix cases in Venezuela, the Netherlands, Belgium, and France, expanding the known mutational spectrum of the disorder with novel mutations in KRT81, KRT83, and KRT86 genes.

In this study, the identification of a novel KAP gene in sheep, named KRTAP36-1, was associated with increased prickle factor in wool, suggesting its potential as a genetic marker for breeding purposes.

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.

In this summary, the researchers describe the Brazilian keratin treatment as a popular hair-straightening process that originated in Brazil in 2003 and has since gained global traction, particularly for smoothing and straightening curly or frizzy hair through a keratin-based product and heat application.

This study found multiple factors, both inherited and acquired, that may lead to bradykinin-mediated angio-oedema, proposing a new classification based on bradykinin production and catabolism imbalance.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This study demonstrated that alkali-modified Kapok fiber significantly enhances the adsorption of collagen, suggesting its potential application in collagen-based dressings.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

This study found that the DKK3-CKAP4 signaling axis is involved in fibroimmune remodeling in androgenetic alopecia and that targeting this pathway may restore a regenerative hair follicle environment, offering a potential therapeutic strategy to counteract hair follicle miniaturization.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

This study reported that recombinant human hair keratins, K37 and K81, showed higher purity and enhanced fibrin clot formation compared to traditional extracts, reducing bleeding time and blood loss in rat injury models.

This article presents a case of a 45-year-old African American man with firm, hyperpigmented papules and pustules on his cheeks and neck, persisting despite various shaving methods.

This study found that controlled thermal straightening can achieve irreversible smoothing of curly hair without chemicals, with effectiveness dependent on temperature and cycles, and silicone enhancing straightening quality.

This study applies the Displacement Framework to explore how hair serves as both a biological and social signal, highlighting the costs of institutional demands for hair straightening in Black communities, which the natural hair movement counters by returning to natural hair.

This study explored how chronic hair pulling behavior serves as a coping mechanism among African American women, particularly through the lens of eroticism, but reports on narratives rather than clinical results.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.

This review details the development of the alpha-helix model for protein structure proposed by Pauling and Corey and confirms its validity through X-ray studies of myoglobin and lysozyme.

In this case report, the authors described how a 27-year-old male developed scarring and penile shortening after a previous lengthening procedure, which was successfully repaired using a pedicled superficial circumflex iliac artery perforator flap combined with a novel hybrid technique.
