This study introduced a new method for extracting red mordant dyes from wool fibers that preserved the fibers for further analysis and allowed for spectrophotometric examination of the dyes' absorption curves.

This study developed and validated an HPLC-UV method for accurately quantifying clobetasol propionate in skin and hair follicles, demonstrating its application in in vitro permeation experiments.

This research reported that liposomal systems made from pig-derived skin lipids enhanced finasteride delivery to hair follicles for treating androgenetic alopecia, showing improved drug deposition, hair length, and growth compared to conventional finasteride forms in vitro.

This study found that both 5-ALA and Photofrin can effectively destroy human microvascular endothelial cells in vitro and cause tissue necrosis in vivo, with Photofrin showing greater efficacy at lower concentrations or power densities.

This review suggests that fractional CO2 laser treatment may be a promising option for treating alopecia areata with a good safety profile.

This study found that keratin 6hf, a type II keratin, is expressed in specific regions of mouse and human hair and suggests potential interactions with keratin 17, impacting hair development and associated disorders.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This study used ultrahigh-resolution optical coherence tomography to observe hair shaft structures, finding melanin granules absent only in white hair, which may explain color differences between black and white hair.

Krt6a-Cre transgenic mice help study gene effects on hair follicle development and tumor suppression.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

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 chapter discusses the structure and function of the skin, detailing its protective roles and the layers that comprise it, but reports no new research findings.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

Lichen planopilaris and frontal fibrosing alopecia are likely the same disease with different clinical appearances.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This review discusses evidence-based guidance for managing primary cicatricial alopecias but reports no new clinical results, highlighting significant gaps in knowledge and the need for more quality trials.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This review discusses the clinical features and treatment challenges of acne keloidalis nuchae, a form of chronic scarring folliculitis, and reports no new results.

This review discusses the varied use and inconsistent reporting of platelet rich plasma in aesthetic surgery, finding that current studies lack consistent methodologies and objective evidence, and reports no new clinical results.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This study found that nanostructured lipid carriers with clobetasol propionate significantly enhance follicular drug delivery compared to commercial cream, and manual massage further doubles follicular retention.

This study found that targeting the hair follicle can be increased by using lipophilic drugs combined with surfactant solutions and propylene glycol.

This review explores the role of Eph receptors and ephrins in skin cell processes, discussing their potential for therapeutic targeting in dermatological disorders, but it presents no new research findings.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

This study reported that alopecia occurred in 2.5% of patients with mycosis fungoides or Sézary syndrome, with some cases resembling alopecia areata and others associated with specific skin lesions.

This narrative piece considers how epigenetic factors may influence the processes of skin wound healing, including hair follicle formation, but it presents no new experimental results.

This study found that coating liquid crystalline nanoparticles with chitosan significantly enhanced the skin permeation of 5α-reductase inhibitors, suggesting a promising strategy for improving topical delivery in androgenetic alopecia treatment.

This study suggests that vitamin D-upregulated protein 1 (VDUP1) might play a unique role in regulating the differentiation of epidermal cells.

This review discusses the analysis of pharmaceutical relics from prehistoric times to the twentieth century and emphasizes the need for a multifaceted approach, but it presents no new experimental results.
