This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study found that in vitro, cultured bulge cells from human hair follicles possess properties of primitive cells, supporting the hypothesis that hair follicle stem cells reside in the bulge area.

In this study, researchers identified novel long non-coding RNAs related to cashmere fineness in goats, highlighting a potential regulatory network involving lncRNA XLOC_008679 and its target gene KRT35.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

This review highlights the light microscopic features of various infectious and non-infectious hair conditions and reports no new clinical results.

This chapter reviews formulation principles for creating cosmetic nanoemulsions and applications targeting skin and hair care, but does not present new experimental results.

This study explored gene expression in Changthangi goats and found that higher expression of keratin-related genes and specific signaling pathways may play a role in the development of Pashmina fiber.

This study shows that environmental contamination affects mummy hair, suggesting that using it to assess ancient people's health or nutrition should be approached cautiously.

This study found that using a ruby laser for hair removal resulted in a significant average reduction of 56.4% in hair density among participants dissatisfied with other methods.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This article reviews current research on animal models for hair regrowth treatments and reports no new findings; it highlights the need for studies comparing therapy efficiency and long-term safety.

This study found that a 2% polyherbal phyto-complex cream containing aqueous extracts of Trichosanthes cucumerina and Abrus precatorius effectively promoted hair growth in preclinical tests, comparable to minoxidil 2%.

This review discusses the clinical features, genetics, and treatment of 21-hydroxylase deficiency, a common type of congenital adrenal hyperplasia, and reports no new research findings.

This case report describes a functional adrenocortical oncocytoma that co-secreted testosterone and cortisol.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This review covers various aspects of hair biology, pigmentation, and development, focusing on genetic and biochemical modulation of hair follicle components but reports no new findings.

This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.

This study found that melatonin at 0.2 g/L for 72 hours most effectively enhances cashmere growth in Liaoning cashmere goats by upregulating the lncRNA MTC, which activates NF-kB signaling.

This study identified a missense mutation in the keratin 71 gene as the cause of autosomal dominant woolly hair/hypotrichosis in a Japanese family, marking the first human mutation in KRT71 linked to a hair disorder.

This review discusses the impact of various external factors like cosmetics, traction, and radiation on hair health and color, but reports no new findings.

This review discusses the potential benefits of phytochemicals for hair care and emphasizes the need for more robust preclinical and clinical studies, without reporting new clinical results.

This study concluded that the process of mummification disfigures facial features, making identification challenging, but commercial shrunken heads retain more defining features compared to ceremonial ones.

This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This study found that moisture sorption properties of wool and hair fibers from various animals were similar, despite different structural features, with sorbed water being more ordered than liquid water.

This study describes a method to estimate endogenous hormone production by neutralizing an endogenous hormone with an oppositely acting hormone.

This review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

This review discusses the potential efficacy of topical antiandrogen therapies for treating androgenetic alopecia and acne vulgaris, finding promising results but highlighting the need for more comprehensive studies.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.
