This study found that wool felting in Ukrainian Carpathian Mountain sheep is linked to significant changes in fatty acid composition, particularly highlighting a decrease in 18-methyleicosanoic acid in bound lipids, suggesting it as a potential marker for cuticle lipid layer damage during felting.

This study found that the expression levels of Siah1 and Siah2 in mice skin vary dynamically during postnatal hair follicle development, suggesting their specific roles in modulating the HIF pathway.

This review highlights current treatment options for frontal fibrosing alopecia, noting that 5-α-reductase inhibitors, intralesional steroids, and hydroxychloroquine have the highest evidence of effectiveness, while other therapies show variable results and need further research.

This review discusses the growing use of scalp hair for elemental analysis in various fields and highlights advancements in analysis techniques, including the future potential of laser ablation ICP-MS, but reports no new clinical results.

This study developed and validated a computational model to optimize skin precooling methods for minimizing thermal damage during laser procedures.

This study identified two evolutionarily conserved ultra-high-sulfur keratin proteins in human and sheep hair follicles, which are specifically expressed in the hair cuticle during the late stages of fiber development.

This study used single-cell RNA-sequencing data from mouse skin to reveal that fibroblasts show high transcriptional plasticity during wound healing, forming transient microniches early on and stratifying scar tissue into distinct molecular layers over time.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

This study suggests that hepatocyte growth factor (HGF) may play a role in hair follicle neogenesis and that an HGF mimetic could enhance skin substitute development.

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.

The laser therapy device effectively increased hair growth in people with androgenetic alopecia.

Men with a certain type of hair loss often use facial moisturizers, and a specific antibiotic treatment may help another hair condition.

This review summarizes recent advancements in follicular targeting for drug delivery via hair follicles and calls for pilot studies in humans to explore potential clinical applications.

This study found that increasing a drug's lipophilicity and adding ethanol to the donor phase can enhance its delivery to the hair follicle, although the precise transport mechanism remains unclear.

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

This study found that acellular dermal matrix scaffolds may facilitate full-thickness skin wound healing by promoting a pro-regenerative immune response through M2 macrophage polarization via the Lamtor1 pathway.

This review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

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 review examines mechanical and chemical causes of hair fiber adhesion failure and fracture patterns in the cell membrane complex, but presents no new experimental results.

This study developed two sensitive chromatographic methods for determining finasteride and tamsulosin hydrochloride in pharmaceutical forms, validated against International Conference on Harmonisation guidelines.

Confocal Laser Scanning Microscopy (CLSM) is a useful tool for studying how drugs interact with skin and diagnosing skin disorders, despite some limitations.

In this study, the authors found that applying hypobaric pressure to the skin significantly increases the transdermal permeation of large molecules by enhancing diffusion, despite the associated skin stretching and hair follicle enlargement not fully explaining this effect.

This study reports that two novel chromatographic methods demonstrated high sensitivity and selectivity for determining aminexil, niacinamide, and pyridoxine HCl in a laboratory-prepared mixture and hair tonic preparation.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.

This article reviews the role of androgen in male pattern hair loss and its impact on hair follicle miniaturization, but it does not present new research findings.

In this study, formulations containing 20% zinc oxide nanoparticles demonstrated stability and improved spreadability without penetrating the deepest skin layers, instead accumulating in skin furrows and hair follicles.

This review discusses current and emerging treatments for benign prostatic hyperplasia and emphasizes the need for further research to optimize treatment selection, but reports no new clinical results.

This review discusses the benefits and drawbacks of low-level laser therapy for various non-surgical conditions based on existing literature, but reports no new clinical findings and suggests further research is needed.

The excimer laser may help hair regrow in alopecia areata patients.
