A missing mK6irs1 gene causes hair loss in mice.

Hair and follicle keratins differ in structure and expression, especially in cysteine content.

This study concluded that male mice are more susceptible to valproic acid-induced autism spectrum disorder than female mice, with noticeable differences in brain histoarchitecture and receptor protein levels.

This review evaluated existing studies on platelet-rich plasma for facial rejuvenation and found limited clinical evidence supporting its effectiveness, suggesting that more research is needed to establish its utility.

This review provides a detailed overview of the causes, prevalence, pathophysiology, clinical presentation, and treatment of beard alopecia, highlighting conditions such as alopecia areata, pseudofolliculitis barbae, and tinea barbae, and aims to serve as a resource for clinicians handling such cases.

This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

This study found that Prdm1 is crucial for whisker development in mice, affecting multiple signaling pathways and possibly playing a role in primates' evolutionary loss of vibrissae.

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 examined the factors contributing to gray hair, such as genetics and lifestyle, and found that while graying correlates with some health conditions, it is primarily a physiological process rather than a pathological one.

This review highlights the potential of nanotechnology for hair follicle regeneration, focusing on strategies such as hair cycle modulation, progenitor cell stimulation, and wound-induced hair neogenesis, while also discussing regulatory challenges that may affect the development of these innovative approaches.

This study reviews the complexities of burn-related skin complications, highlighting postburn pruritus, dyspigmentation, and the risk of malignant ulcers, while offering a framework for evidence-based management through various treatment approaches.

Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.

This article discusses various aspects of hair and scalp health, ancient philosophical perspectives on hair, and causes of hair disorders in children, without reporting new clinical results.

This review synthesizes current evidence on platelet-rich plasma for dry eye disease and reports no new results; the authors emphasize the need for standardized trials to validate these approaches.

This review discusses various diagnostic and treatment strategies for canine prostate diseases, including pharmacological options and advanced procedures, but reports no new clinical results.

This review discusses recent advances in understanding hair growth mechanisms and reviews current and emerging therapies, but it presents no new clinical results.

This study, through a review of existing literature, observed that massage techniques may serve as a beneficial complementary therapy for male androgenetic alopecia by enhancing blood circulation and overall follicle nutrition, with combined approaches possibly increasing treatment efficacy despite a lack of standardized protocols.

Monilethrix involves multiple genes affecting hair structure, including DSG4 mutations.

In this study, researchers found that coordinated intercellular Ca2+ signaling among basal stem cells in mice is crucial for cell cycle progression and tissue-wide communication during epidermal regeneration.

In this study, researchers observed that acute stress increased levels of the enzyme 5αR2 in the medial prefrontal cortex of male rats, affecting stress reactivity, but this effect was not seen in females.

This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

In this systematic review, the authors reported that both FUE and FUT hair transplant techniques induce oxidative stress and inflammation, impacting graft survival, but interventions like PRGF, CO2 laser, and dermal microtissues can enhance healing, reduce inflammation, and improve follicular survival.

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.

KRTAP10 proteins help form the hair shaft's tough outer layer by interacting with specific hair keratins.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

In this case report, a dog was diagnosed with dermatophytosis, a zoonotic fungal infection common in humid climates, presenting with alopecia in the neck and ear regions.

This study observed varying levels of polyamines in different compartments of rat hair follicles, indicating their potential involvement in hair growth, especially in the matrix and inner root sheath layers.

Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.
