This article outlines the rationale, design, major findings, and updated objectives of the ongoing Rotterdam Study, without presenting new research data.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This review discusses the identification and characteristics of melanocyte stem cells, emphasizing their role in hair pigmentation, greying, and skin repigmentation, but reports no new research findings.

Hair growth and pigmentation in mice involve specific stages crucial for research.

This review discusses the roles of Eph receptors and ephrins in various diseases, highlighting their potential as therapeutic targets, but it presents no new research findings.

This updated guideline from the British Association of Dermatologists discusses current recommendations for managing alopecia areata but reports no new clinical research findings.

This article proposes five different mechanisms for telogen effluvium, supported by clinical findings, based on changes in different phases of the hair cycle.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

This review discusses recent advances in skin penetration mechanisms, specifically focusing on the enhanced understanding of the follicular pathway and its implications for transdermal therapies, immune system targeting, and nanoparticle safety.

This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

This study found that recombinant human leukocyte interferon alfa-2a achieved a 64% overall antitumor response rate in patients with early and advanced cutaneous T cell lymphoma and was generally well-tolerated.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This review discusses the complexities of diagnosing and treating iron deficiency related to nutritional anemia and hair loss, concluding that routine screening and supplementation for hair loss are not yet supported by sufficient evidence.

PGD2 stops hair growth and is higher in bald men with AGA.

This study found that lifestyle interventions improved body composition, hyperandrogenism, and insulin resistance in women with PCOS, but did not affect glucose tolerance, lipid profiles, or clinical reproductive outcomes.

This study found that psychoemotional stress disrupts hair growth in mice by terminating anagen and suggests a potential pathway for pharmacological management of stress-related hair loss in humans.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This review discusses strategies for developing semi-solid topical generic products to match the quality of reference-listed drugs, using concepts like quality by design and reverse-engineering, but reports no new results.

This article discusses the role of estrogens in skin aging and reports no new findings; it highlights the potential of selective ER modulators to improve skin health without systemic side effects.

This study found that 94% of healthy men reported low libido and 92% reported erectile dysfunction as persistent sexual side effects after using finasteride for male pattern hair loss, with these effects lasting on average 40 months post-discontinuation.

This case report describes complete hair regrowth in a patient with alopecia universalis and improved psoriasis after treatment with the oral Janus kinase inhibitor, tofacitinib.

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 article reviews the effects of menopause on skin aging and suggests that hormone replacement therapy may help reverse some of these changes.

This study found that fluoxetine did not demonstrate short-term efficacy in treating trichotillomania in a placebo-controlled, double-blind crossover setting.

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

This study found that the mammalian hairless gene encodes a corepressor protein that interacts with thyroid hormone receptors, providing insights into hair loss syndromes in humans and mice.

This review discusses the role of jumonji family proteins in chromatin regulation and development, highlighting their involvement in transcriptional repression and histone demethylation, but reports no new experimental findings.
