This study found that increasing hair loss in men was associated with appearing older, less attractive, and less successful, but more family-oriented and likeable, highlighting the influence of hair loss on first impressions.

This case report suggests that premature aging may contribute to weakened immunity and the development of autoimmune diseases.

Scientists made nanoparticles from human hair proteins to improve drug delivery.

This review discusses the psychological and neurobiological aspects of trichotillomania and reports no new results, emphasizing the need for further research on its treatment and neural mechanisms.

Human hair keratin can be used in many medical applications.

This study found that lower salmon availability was associated with higher stress hormone levels in grizzly and black bears, influencing their physiological responses and competitive behaviors.

In this study, researchers found that human fingerprint ridges are formed through a modified hair follicle developmental process and spatial patterns influenced by specific signaling pathways.

This review outlines the role of mechanical forces in the development of sensory organs like eyes and ears, emphasizing insights from recent animal studies and microfabricated organoid systems; it presents no new experimental results.

This study found that HFV70 cryogels, made from Flammulina velutipes extract and hydroxyethyl cellulose, effectively promoted rapid hemostasis and tissue regeneration in full-thickness skin defects in rats, demonstrating improved hemocompatibility, cytocompatibility, antimicrobial, and antioxidant properties.

Fibroblast bioelectric signaling can promote hair growth and may help treat hair loss.

This study found that extracts from heterotropic cultures of Scenedesmus deserticola JD052 enhanced hair-inductive properties in human dermal papilla cells more effectively than photoautotrophic extracts, likely through activation of AKT/β-catenin signaling, despite similar loliolide content.

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 study found that mutations in the hairless gene in mice disrupt hair follicle integrity during catagen, leading to baldness due to disintegrating epithelial structures and loss of normal dermal papilla.

This study found that the gene SRD5A1, associated with methylation changes due to early-life environment, may play a role in altering reproductive phenotypes in women by delaying pubertal onset and decreasing ovarian reserve.

This study identified a recurrent mutation in the endothelin receptor type A associated with mandibulofacial dysostosis with alopecia, and proposed a mechanism involving increased ligand affinity due to structural changes.

In this study, researchers used Raman spectroscopy to identify melanin-specific features in mouse hair as potential biomarkers for gamma-radiation exposure, achieving a sensitivity of 88% and specificity of 83%, with classification accuracy declining over time beyond 7 days post-irradiation.

This meeting abstract details various lectures and workshops from the 30th Annual Meeting of the American Society of Andrology, including findings on genetic and physiological factors affecting male fertility, but reports no new clinical results.

This study reviews the role of skin stem cells in aging and explores how organoids, as opposed to traditional methods, can advance research into aging skin and regenerative therapies.

This review explored the causes of hair graying and evaluated how plant-derived extracts and phytochemicals might alleviate it, noting that certain compounds showed potential in enhancing melanocyte function, reducing oxidative stress, and influencing stress-related pathways based on experimental evidence.

In this study, a hydrogel derived from Andrias davidianus secretion, combined with micronized amnion, promoted skin regeneration and achieved scarless healing in rats, suggesting potential for clinical use.

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 found that the Wnt/β-catenin signaling pathway activates melanocyte stem cells, promoting hair follicle regeneration both in vitro and in vivo.

This study demonstrated that bioengineered hair follicles reconstituted from embryonic skin cells and transplanted into hosts can restore physiological hair functions, suggesting potential applications for treating alopecia.

This study found an association between a splice site variant in the KRT71 gene and curly hair in Selkirk Rex cats, identifying a significant locus on chromosome B4.

This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

This study found that serum calcium, serum ferritin, and vitamin D3 levels were lower in students with premature graying of hair compared to controls, suggesting a potential role in the condition.

The article concludes that studying how skin forms is key to understanding skin diseases and improving regenerative medicine.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.
