This article reviews the causal mechanisms of hair follicle disorders, focusing on inflammation, genetics, environment, and hormones, but it reports no new clinical results.

This study found that minoxidil provides cardioprotective effects in guinea-pig heart cells through selective activation of mitochondrial ATP-sensitive potassium channels.

This study found that in vitro, cultured bulge cells from human hair follicles possess properties of primitive cells, supporting the hypothesis that hair follicle stem cells reside in the bulge area.

This article reviews potential animal models for studying androgenetic alopecia and reports no new experimental results; the authors highlight the need for further development of rodent models.

This review discusses major advances in understanding inherited hair diseases through genetic research and reports no new clinical results; the authors emphasize the potential for new preventive and therapeutic tools.

This study found that the PSEN1-P242LfsX11 mutation in hidradenitis suppurativa influences cytokine and chemokine expression in macrophages, potentially affecting inflammatory responses.

This study found that NFI-C plays a crucial role in the transition from the telogen to anagen phase of the hair follicle cycle, affecting hair growth initiation in mice.

This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

In this study, researchers found that petroleum ether extract of Eclipta alba significantly stimulated follicular keratinocyte proliferation and reduced TGF-β1 expression in nude mice, suggesting potential use for certain types of alopecia.

This review discusses the classic skin characteristics of hypothyroidism, notably generalized myxedema caused by increased glycosaminoglycan deposition, and reports no clinical results.

This review discusses recent advances in understanding the pathogenesis of autoimmune alopecia areata and reports no new clinical results; it highlights potential for developing more effective treatments.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

In this small study, topical minoxidil 2% was associated with an increase in normal hair shaft production in patients with Monilethrix without any reported side effects.

This study found that alopecia in captive Rhesus macaques may be linked to chronic hypersensitivity dermatitis with CD4+ cell inflammation, possibly influenced by altered housing and reduced pathogen exposure.

This review discusses recent advances in the genetic understanding of inherited hair and nail disorders and reports no new clinical results.

This review discusses the latest understanding of androgenetic alopecia, including stem cell niches in hair follicles, and highlights emerging treatments like growth factors and platelet-rich plasma without new clinical findings.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

This study found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.

In this study, researchers reported that CD34 expression in the isthmic region of canine hair follicles suggests a potential stem cell compartment in this area.

This study found that deleting the Hes1 gene disrupts hair regeneration by delaying anagen initiation and shortening the anagen phase, suggesting it's crucial for maintaining hair cycle homeostasis.

This study found that acne inversa is primarily an epithelial-driven disease, with cyst-forming tendrils causing inflammation due to rupture and the release of debris, highlighting limitations of punch biopsies for analysis.

The study suggests that abnormal activation of hair follicle stem cells and Wnt10b/β-catenin signaling may contribute to the development of sebaceous neoplasms.

This review discusses the topical use of systemic drugs for cutaneous disorders and reports a lack of strong evidence from randomized controlled trials, highlighting the need for larger comparative effectiveness studies.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

This study identified a novel insertion mutation in the hairless gene that may contribute to the development of congenital atrichia with papular lesions in a Pakistani family.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study suggests that damaged anagen hair follicles have the capability to repair themselves and resume growth by mobilizing extra-bulge epithelial cells, particularly after injuries like chemotherapy and radiotherapy.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.
