This study suggests that mesenchymal stem cell therapy may improve cell viability and regulate key signaling pathways in vitro for treating alopecia areata.

This review summarizes recent progress in human hair follicle bulge cell research, particularly the characterization and isolation of these stem cells, but reports no new experimental results.

This review presents current evidence on medicinal plants and their phytoconstituents, such as phenolic compounds, used in acne treatment, highlighting their potential as alternatives to conventional therapies due to issues like antibiotic resistance and high cost.

This review discusses targeting host cell proteases as a novel approach to inhibit SARS-CoV-2 infection, highlighting transcriptional modulation and enzymatic inhibition as promising therapeutic strategies, but it reports no new clinical findings.

This exploratory study found that cannabidiol (CBD) at higher concentrations may inhibit hair growth by promoting the onset of catagen in human hair follicles, while lower concentrations showed potential anti-inflammatory effects without promoting catagen.

This study found that forming spheroids using silicone micro-wells improved the viability and neural differentiation potential of human adipose-derived stem cells after thawing.

This review examines the role of P-cadherin in skin and hair biology, emphasizing its importance in human hair growth, cycling, and pigmentation, and reports no new research findings.

This article discusses follicular cell implantation as a potential solution for hair restoration limitations, but notes inconsistencies and challenges in human applications, reporting no new clinical results.

This review discusses the extragenital effects of ovarian steroids, particularly focusing on aesthetic endocrinology, which suggests estrogens may slow skin aging post-menopause, though hair loss treatment efficacy is mainly confirmed for minoxidil.

This study found that activating CB1 receptor signaling in human hair follicles increased stem cell proliferation while reducing differentiated cell survival, suggesting CB1's role as a survival stimulus for epithelial stem cells.

This review article summarizes the potential role of advanced medical therapies—using genes, cells, and/or tissue engineering—in treating various types of alopecia, by examining clinical research, basic studies, and ongoing trials.

This laboratory study found that activated platelet‐rich plasma supernatant enhanced hair growth signaling pathways in cultured human dermal papilla cells, suggesting potential for treating androgenic alopecia.

This review discusses common skin conditions in primary care settings and provides guidance on differential diagnoses and selecting appropriate topical treatments, but it reports no new clinical results.

This article reviews recent advancements in understanding hair follicle biology, with a focus on the potential for gene therapy in treating alopecia, but it reports no new research findings.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

This study found dependencies between genetic variants and various phenotypes related to fetal and early childhood growth and neurological development in healthy infants, suggesting significant gene candidates for further investigation.

In this study using a mouse model, ECM/SVF-CM, derived from adipose-derived stem cells, was observed to stimulate hair growth more effectively than SVF-CM by promoting cell proliferation, neovascularization, and anagen induction, which may support its potential as an improved treatment for hair loss.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

This study found that hair canal and follicle diameters, outer root sheath area, and terminal-to-vellus hair ratios were significantly reduced in androgenetic alopecia patients compared to normal controls.

This study demonstrated that the biomimetic peptide PTP20 may help preserve hair pigmentation and reduce greying by enhancing melanocyte function and increasing melanin production in human hair follicles.

In this study, researchers developed a simple, non-invasive method to monitor circadian gene expression using whole hair root cultures, finding that elderly dementia patients' peripheral clocks still oscillate similarly to younger, healthier individuals, which suggests cellular senescence minimally affects some aspects of circadian rhythms.

This study demonstrated that troxerutin may protect human dermal papilla cells from H2O2-induced damage and suggests potential in treating alopecia by inhibiting ROS-mediated cellular damage.

In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.

This study found that doxorubicin induces hair follicle apoptosis through TRAIL receptor signaling, providing insights for managing chemotherapy-induced hair loss.

This article discusses the potential of using human hair follicles as a model to study prolactin's regulation and activities but reports no new experimental findings; the authors suggest further research in this area.

In this study, an ethanol extract of Crinum asiaticum was observed to significantly increase hair-fiber lengths and promote hair growth in rat vibrissa follicles and C57BL/6 mice.

This study found that in Japanese, German, and American females, changes in hair lipid patterns with age may reflect alterations in sebum excretion and affect hair texture.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

In this study, researchers identified gremilin-2 as a highly specific gene to the dermal sheath cup, suggesting it plays a key role in maintaining its properties.

In this study, basal cell carcinoma developed in Ptch-deficient mice only after chemical treatment, not skin wounding, suggesting a second unknown event is necessary for tumor formation.
