This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.

This study observed defects in hair cuticle cross-linking in some, but not all, mouse mutants with sparse or structurally unsound hair.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

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 found that activating Nrf2 in human hair follicles significantly reduced oxidative stress, lipid peroxidation, and protected against hair growth inhibition, suggesting a protective role for Nrf2 against redox insult in this context.

This study found that applying topical tretinoin can influence follicular sulfotransferase expression, enabling 43% of predicted nonresponders to minoxidil to respond positively in the context of androgenetic alopecia.

This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.

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.

This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.

This study detected higher expression of p63 in occipital scalp areas compared to frontal areas, with minimal changes in beta-catenin expression and a novel finding of CD34 positive cells in hair follicles' outer root sheath.

This study found that ascorbigen increased growth of dermal papilla cells but did not significantly protect against chemotherapy-induced alopecia in a mouse model, suggesting limited effectiveness for hair regrowth in this context.

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.

This review discusses the plasticity of epithelial stem cells in regenerative contexts and reports no new research findings; the authors highlight potential implications for regenerative medicine and cancer.

The study found that over-expressing ornithine decarboxylase in the outer root sheath of the hair follicle in mice increases UVB-induced tumor growth and invasive squamous cell carcinoma compared to inter-follicular epidermal keratinocytes.

Pharmacists play a key role in managing the use of anxiety medications and ensuring patients use them correctly.

This review discusses the application of lipid nanoparticles for enhancing drug delivery through hair follicles and reports no new clinical results, emphasizing the potential role of sebum-like lipids in this context.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This study found that PGF 2α receptors were predominantly present in the inner root sheath of the bulb and stem of human eyelashes during the anagen phase.

This review discusses the role of fibroblast heterogeneity in kidney pathology, particularly their contribution to tertiary lymphoid tissue formation, and reports no new results.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This paper discusses the role of Runx1 in epithelial biology and pathology, highlighting its dual function as a tumor promoter and suppressor in different contexts, and reports no new experimental findings.

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This article reviews innovations in hair cosmetics, focusing on esthetic procedures and products in the Indian market, and reports no new experimental findings.

This study found that two pre-Hispanic mummies from the Andean coast had well-preserved hair with significant amounts of heavy metals like iron, lead, bromide, and occasionally arsenic, revealing their historical context.

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 study found that hair treated with shampoo containing water-soluble silicone demonstrated smoother sliding and better detangling, compared to shampoo with water-insoluble silicone, due to differences in conditioning film formation.
