This study observed that in a series of 28 patients with different types of alopecia, specific trichoscopic markers like exclamation-mark hairs and yellow dots helped distinguish alopecia areata from conditions like lichen planopilaris and discoid lupus erythematosus, which showed follicular ostia loss and white scarring.

In this observational study, SOX10 was expressed in 53 out of 81 examined hair follicles in patients with alopecia areata and showed a significant positive relation with the perifollicular lymphocytic infiltrate, suggesting that melanocytes may play a role in the disease's autoimmune pathogenesis.

This review discusses the integration of omics analyses in androgenetic alopecia research, reporting no new clinical results but suggesting that collaborative multi-omics studies may enhance understanding of AGA's pathomechanisms.

This study reviewed cases of filler-induced alopecia and found that hyaluronic acid injections were most commonly associated with this condition, highlighting that hyaluronidase treatments can rapidly restore hair density, while alternative interventions need further exploration.

In this case report, the authors describe a rare association of alopecia universalis with frequently relapsing nephrotic syndrome in a 3-year-old girl, suggesting a possible genetic and immune-related cause, and note that tofacitinib treatment was ineffective in her case.

This study found that acute alopecia areata features more terminal telogens and vellus hairs, while chronic alopecia areata shows more follicular streamers and nanogen hairs.

In this review, the authors detailed the clinical, trichoscopic, and histopathological features of hair disorders linked to autoimmune diseases, highlighting the role of dermatologists in identifying possible underlying autoimmune conditions in patients presenting with hair loss.

This study found that transplanted hair follicle-associated pluripotent stem cells in mice differentiated into keratinocytes and stimulated hair growth by producing mature hair shafts.

This review synthesizes current evidence on alopecia areata, detailing its clinical features, pathogenesis, and treatment options, but does not present new clinical results.

This case study highlights the rare simultaneous presentation of syphilitic alopecia and neurosyphilis in a 61-year-old man, underscoring the importance of recognizing this combination for timely treatment.

This quiz article provides a series of dermatological diagnosis questions based on a Journal of Investigative Dermatology article and includes explanations but reports no original research findings.

This study found that patients with alopecia areata and androgenic alopecia had significantly increased mast cell infiltration, which was influenced by age and disease severity, especially in alopecia areata.

This review suggests that platelet-rich plasma may be a promising treatment for immune-mediated alopecias, including alopecia areata and primary cicatricial alopecias, but definitive recommendations are limited due to insufficient high-quality evidence.

This review discusses advances in using tissue engineering to improve the inductivity of dermal papilla cells for hair follicle restoration and reports no new clinical results.

This report describes a rare case of lipedematous alopecia in a young Caucasian man, a condition primarily seen in African-American females, presenting with specific scalp and histological characteristics.

In this review, researchers summarize drugs associated with scarring or permanent hair loss, notably after chemotherapy and tyrosine kinase inhibitor treatments, emphasizing the need for stronger evidence and long-term follow-up studies, as current findings are mostly from case reports.

This review discusses the role of dermal cells in hair follicle regeneration and morphogenesis and highlights their potential therapeutic implications, but it reports no new empirical findings.

JAK inhibitors show promise for treating alopecia areata, but more research is needed.

This review discusses dermal cell heterogeneity in wound healing and scar formation, highlighting the varied roles of different fibroblasts and the potential of skin substitutes without presenting new clinical results.

This review evaluates the efficacy and safety of topical sensitizers in treating alopecia areata but reports no new clinical findings.

This study found that pro-inflammatory cytokines and apoptotic mechanisms, specifically involving granzyme B and Fas pathways, are associated with chronic alopecia areata, indicating their potential role in the disease's persistence.

Alopecia areata is caused by an immune response, and targeting immune cells might help treat it.

This study found that valproic acid promoted hair re-growth in C3H mice by activating the Wnt/β-catenin pathway, suggesting its potential as a treatment for alopecia.

This review explores the hair follicle microbiome's interaction with the immune system, discussing its potential clinical implications for scalp health and disease but reports no new clinical results.

This review outlines the role of dermal fibroblasts in wound healing and highlights their potential in developing new cellular therapies, but reports no new clinical results.

This review discusses various therapeutic agents for alopecia areata, categorized by efficacy and safety, and highlights the lack of curative treatments and long-term outcome studies.

This study found that ectodermal precursor cells derived from human induced pluripotent stem cells may enhance hair follicle morphogenesis through improved epithelial-mesenchymal interactions when cocultured with dermal cells.

JAK inhibitors and platelet-rich plasma show promise for treating alopecia areata.

This review explores multidisciplinary advances in understanding alopecia areata, including epidemiology, pathogenesis, and innovative treatments, but reports no new research results.
