In this study, researchers observed that patients with androgenetic alopecia show differences in scalp microbial communities compared to the general population, including an increase in Cutibacterium acnes, particularly in males, which may interact with lipid and immune pathways to contribute to hair follicle miniaturization.

This review explores the link between androgenetic alopecia, advanced glycation end products, and RAGE, noting their potential role in exacerbating oxidative stress and inflammation related to hair follicle miniaturization.

In this case report, a pancreatic adenocarcinoma with liver and omentum metastases was found in a cat, whose clinical signs included anorexia, diarrhea, lethargy, and non-pruritic glistening alopecia.

This review discusses the factors involved in androgenetic alopecia, emphasizing genetic susceptibility as a key contributor and detailing how follicle miniaturization completes the condition's development; it reports no new clinical results.

This study reports that some patients with androgenetic alopecia may also exhibit clinical and histological features of inflammation and fibrosis, similar to those found in lichen planopilaris.

This review examines the histopathologic features of four common types of noncicatricial alopecia and reports no new clinical results.

This review summarizes recent findings on scalp involvement in pemphigus vulgaris and pemphigus foliaceus, highlighting diagnostic methods and their underlying histopathological, immunopathological, and clinical features, but reports no new clinical results.

The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.

This case report describes the first dermoscopic evaluation of alopecia areata-like disease in a dog, where the condition mirrored human cases in terms of clinical presentation and treatment response.

This article discusses treatment approaches for a 33-year-old man with progressive hair loss, including the potential use of scalp reduction surgery, and reports no new clinical results.

This paper discusses various histologic features to distinguish types of alopecia and reports no new clinical findings.

This study evaluated salmon-derived exosomes combined with microneedling as a treatment for androgenetic alopecia, reporting significant improvements in hair density, follicular health, and scalp microenvironment, with no serious adverse events observed in the 20 patients after 12 weeks.

This study found that the multifunctional exosome-based delivery platform EX104 reversed hair follicle miniaturization and promoted hair growth in a mouse model of androgenetic alopecia, performing comparably to minoxidil while also enhancing capillary growth and follicular proliferation.

This paper identifies challenges in diagnosing alopecia variants, emphasizing the importance of pathologists understanding hair follicle histology, biopsy types, and collaborating with dermatologists to improve diagnostic accuracy.

In this study, the researchers reported that early diagnosis and treatment of fibrosing alopecia in a pattern distribution may arrest or potentially reverse disease progression, though some patients experienced continued hair loss.

This study aims to describe the trichoscopic pattern of chemotherapy-induced alopecia and its changes during different phases of chemotherapy.

This review discusses common mistakes in follicular unit transplantation and provides guidance for practitioners to enhance patient outcomes, but reports no new clinical results.

This study found that follicular acantholysis is a common histopathological feature in pemphigus, with differences in depth between pemphigus vulgaris and pemphigus foliaceus lesions that may aid in diagnosis.

This review explores the complex causes and treatment options for alopecia, emphasizing that current therapies mainly offer symptomatic relief, while new advancements like stem cell approaches and improved drug delivery systems show promise for addressing underlying disease mechanisms.

This review highlights that alopecia's complex causes include hormonal, genetic, and environmental factors, and discusses traditional and emerging therapies, suggesting a need for multi-targeted, mechanism-based treatments to improve long-term management and efficacy.

This article previews a Journal of Investigative Dermatology quiz on diagnosing male androgenetic alopecia and offers no new research results.

In this study, researchers suggest that hair follicle miniaturization in conditions like androgenetic alopecia may result from impaired conversion of quiescent stem cells to progenitor cells, influenced by the follicular niche, its collagen network, and various mechanical constraints.

This article discusses the ontological and hormonal sensitivity hierarchy within follicular units and does not report new experimental results.

This study found that apoptosis was more prevalent in hair follicles of women with female pattern hair loss, particularly in miniaturized follicles, and was associated with follicular inflammation.

This paper discusses key mechanisms of androgen metabolism in androgenetic alopecia and reports the effectiveness of treatments like oral finasteride and topical minoxidil, highlighting the limited success rate due to factors like follicular inflammation.

This source describes SH‑1 as a next-generation androgen receptor antagonist designed for localized treatment of androgenetic alopecia, aiming to reverse follicular miniaturization while maintaining endocrine balance. Unlike traditional therapies, SH‑1 offers tissue-specific action, avoiding systemic effects.

In this study, DHT inhibited hair regrowth and promoted hair follicle miniaturization in mice, with skin-resident myeloid cells enhancing their interaction with hair follicular cells, especially in females.

This study observed that fibrosis occurs in the bulge region of hair follicles affected by androgenetic alopecia and is correlated with the hair miniaturization process.

This study found that age and follicular miniaturization were extremely weak predictors of total hair count in women with hair loss.

This article discusses various types of primary cicatricial alopecias and reports no new clinical results; it emphasizes the importance of accurate diagnosis for effective management.
