This study suggests that decreased PPARgamma function may trigger the pathogenesis of lichen planopilaris, and PPARgamma-targeted therapy could be a potential treatment method.

This study found that flower extracts of Wedelia trilobata may serve as a promising active ingredient for cosmeceutical products due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This literature review found a significant increase in men seeking non-surgical and surgical cosmetic procedures, driven by improved self-confidence, with high efficacy and satisfaction reported by specialists providing advanced, patient-focused care.

This study found that mice exposed to low humidity showed altered epidermal gene expression, which was modulated by topical emollient application; this suggests emollients may help manage dry skin in low-humidity environments by affecting specific gene pathways.

This study identified a unique circulating microRNA signature associated with severe alopecia areata, distinguishing it from other inflammatory skin conditions and suggesting these miRNAs as non-invasive biomarkers for diagnosis and potential therapeutic targets.

This article explores the potential mechanisms by which polydeoxyribonucleotide (PDRN) could improve skin quality, slow aging, and enhance skin regeneration, but reports no new clinical findings.

This in-silico study found that Finasteride interferes with neurotransmitters and may increase psychopathology when it decomposes into a carboxylic acid similar to Cortisol.

This article reviews existing and emerging treatment methods for androgenetic alopecia non-surgically, suggesting some could potentially reverse disease progression, but notes each approach still faces certain limitations.

This article discusses the role of the hair follicle as a miniorgan involved in bioelectricity and energy transfer in living organisms, but it reports no new research findings.

This narrative review reports that scalp micropigmentation offers immediate cosmetic improvements in hair density appearance, but does not promote actual hair regrowth and results vary based on the operator's skill.

In this study, exposure to Myrtus communis leaf extract significantly reduced IL-1α expression and increased VEGF expression in human keratinocytes, which may relate to its traditional use for hair loss and wound healing; further research is necessary to understand its mechanisms.

This narrative review explores mechanisms linking COVID-19 with hair loss, highlighting how cytokine-mediated inflammation, androgen-regulated TMPRSS2 expression, and direct follicular injury contribute to the condition. It suggests that vitamin D could potentially mitigate this hair loss by suppressing inflammation and viral entry, warranting further research.

This review discusses the mechanisms underlying the collapse of hair follicle immune privilege in alopecia areata and emphasizes the importance of therapeutic strategies aimed at restoring immune tolerance.

This study found that in Liaoning cashmere goats, overexpression of the PIP5K1A gene enhances skin fibroblast proliferation, while interference with this gene reverses melatonin-induced proliferation, and PIP5K1A regulates certain miRNA expressions, suggesting a role in improving cashmere yield and quality.

This review discusses the roles of prostaglandins in hair loss and highlights their potential as targets for new alopecia treatments, but reports no new clinical findings.

This study found that overexpression of Hoxc13 in GC13 mouse models affects hair follicle differentiation by interacting with medulla-specific genes, particularly Foxq1, suggesting a regulatory pathway for medulla differentiation.

This study found that mutations in the Foxn1 gene in nude mice affect not only hair but also nail structure and differentiation, offering insights into nail hypergranulosis pathogenesis relevant to human nail diseases.

This review details the advancements and benefits of fractional erbium:YAG resurfacing lasers for treating photoaging, acne scarring, and dyschromia, but it presents no new clinical results.

This study identified several genes and signaling pathways, such as Wnt and MAPK, involved in fur development in Chinchilla rex rabbits, providing insights into skin and hair follicle growth.

This study found that DHT treatment led to reduced cell growth, increased cell death, cell cycle arrest, ROS production, and senescence in normal human dermal papilla cells, potentially mediated by altered miRNA expression.

This study found that miR-339-5p negatively regulates loureirin A-induced differentiation of hair follicle stem cells, potentially impacting skin repair and regeneration by inhibiting the Wnt/β-catenin signaling pathway.

This study found that dihydrotestosterone (DHT) regulates the degradation of p27 in MCF-7 breast cancer and OVCAR-3 ovarian cancer cells, involving SKP2 as a key factor.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.

In this study, transcriptome analysis identified 68 differentially expressed miRNAs in human dermal papilla cells treated with hydrogen peroxide, suggesting they play a significant role in growth arrest and apoptosis.

This study found that para-phenylenediamine induces cytotoxic effects in normal human hair dermal papilla cells by altering microRNA expression and causing cell death, cell cycle arrest, and oxidative stress.

This study examined the effects of WNT10B on dermal papilla cells in vitro, finding that it alters gene expression, decreases protein synthesis, and upregulates a specific signaling pathway, potentially influencing hair follicle morphogenesis.

This study found that Wnt5a expression may suppress cell differentiation and induce an inflammatory response in HaCaT keratinocytes, which could be relevant to psoriasis development.

This study observed that ethanol extracts of Lygodium japonicum spores significantly reduced inflammatory responses in LPS-stimulated murine macrophages in vitro by negatively regulating p38 MAPK and NF-κB.

This study identified genes potentially involved in hair and cashmere growth in the Laiwu black goat, highlighting specific gene expression differences between hair-growing and hairless skin.
