Woman has discoid lupus, frontal fibrosing, and androgenetic alopecia.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

This study found that the lack of expression and deletion of specific hair keratin genes on chromosome 7q36 in Hirosaki hairless rats suggests the crucial role of these genes in hair growth.

This article reviews the potential of topical minoxidil to cosmetically thicken hair in some individuals with male pattern hair loss, but it reports no new clinical results.

This study developed a stable cell line model to evaluate hair differentiation activity, offering a new tool for screening drugs that promote hair growth using mouse iPS cell-derived systems.

This article reviews the characteristics, common locations, and causes of epidermoid cysts, noting that surgical excision is the standard treatment, but it reports no new clinical findings.

This study suggests that fish oil, specifically its components EPA and DHA, play a beneficial role in promoting skin health by supporting epidermal growth and reducing proinflammatory cytokines.

In this study, APC collagen peptides were observed to enhance hair elasticity and gloss in human hair follicles by increasing amino acid and lipid component levels, suggesting their potential benefits for improving hair qualities.

This study found that the PLEE method increased hair protein extraction efficiency threefold and that bleaching hair reduced the coverage of keratin and associated proteins, leading to poorer hair quality, though it did not affect the overall protein identification.

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 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 review discusses the genetic and biological factors influencing hair curliness, revealing strong links to specific protein variations, and reports no new clinical results.

This study observed that fetal hair follicle melanocytes varied in morphology and development stages, with melanosomes undergoing degradation into irregular pigment particles within keratinocytes.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This study found that keratin and other hair proteins in humans are extensively modified posttranslationally, which helps explain the structural characteristics of mature hair.

This study suggests that degraded human hair shafts are highly resistant to contamination by exogenous DNA, making them a valuable source for forensic and ancient DNA analysis.

This study found that proteomic analysis can distinguish hair samples across different ethnicities and body regions based on keratin protein levels, which may aid forensic hair identification.

This study concluded that the curliness of human hair, regardless of ethnicity, originates from the inhomogeneous internal nanostructure due to differences in the distribution of two types of cortices.

This study describes GPRC5D's unique expression pattern in tissues that produce hard keratin, with retinoic acid inducing its expression in hair bulb cells and affecting keratin gene regulation.

This article reviews the challenges in studying keratin proteins and emphasizes the potential of modern proteomic techniques to advance their research, but it reports no new findings.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

This study found that the Ovol2-Zeb1 regulatory circuit is crucial for controlling directional migration and proliferation in epithelial cells, facilitating skin regeneration and repair in mice.

This study found that the orphan protein Plet-1 is expressed in specific keratinocytes of mouse hair follicles and may regulate keratinocyte interactions with inert tissues by affecting migration and adhesion.

This study found that mutations in type I IRS keratin genes disrupt keratin protein complexes in mice, suggesting crucial roles for these genes in proper hair coat formation.

In this study, researchers observed that EGFR deficiency in the epidermis affects gene expression related to cell differentiation and structure, highlighting spatial and temporal roles of EGFR during skin and hair follicle development.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

This study found that transgenic mice with keratinocyte-specific overexpression of CtBP1 exhibited abnormal hair follicle development, suggesting CtBP1 may play a pathogenic role in hair morphogenesis.

This study suggests that extracting hair proteins at relatively high temperatures may enhance their hemostatic properties by altering their secondary structure and increasing the precipitation of soluble fibrinogen.

This study found that CD99 is strongly expressed in the basal cells and hair follicles of normal adult and developing fetal skin, with expression patterns becoming similar after 20 weeks of gestation.
