This study found that miniaturization of hair is present in some women with androgenetic alopecia, but diagnosis may also be based on differences in hair shaft diameter between scalp regions.

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 observed that hair follicles in hair loss patients had increased levels of Propionibacterium acnes, potentially linked to elevated immune response gene expression in miniaturized hair follicles.

This article introduces the term "anisotrichosis" to describe the significant variation in hair shaft diameters observed in pattern alopecia, drawing a parallel to anisocytosis seen in blood smears, but reports no new research findings.

This case report describes a 45-year-old Japanese woman with metastatic cervical cancer, including rare scalp metastases, who experienced severe scalp tenderness and patchy hair loss before her death.

In this study, hair loss in Japanese men with androgenetic alopecia was found to be primarily due to hair follicle miniaturization rather than hair shedding, particularly in those aged 25 and older.

Reflectance confocal microscopy can tell apart white dots on the scalp as either sweat gland ducts or hair follicle openings.

This review found that dutasteride is more potent than finasteride as a dual receptor dihydrotestosterone blocker for treating androgenetic alopecia and shares a similar safety profile in terms of fertility, teratogenicity, neurotoxicity, and hepatotoxicity.

This article reviews alopecia areata incognita, a rare condition mostly seen in young women, and discusses its similarities and differences with telogen effluvium; however, it reports no new clinical findings.

This study reports that horizontal sections of scalp biopsies improve the diagnosis of alopecia areata, especially when characteristic inflammatory infiltrates are missing.

In this study, researchers found that as androgenetic alopecia severity increased, the hair follicle matrix and dermal papilla's volume and cell nuclei number decreased, especially in the papilla.

This article discusses a potential link between adipocyte-myofibroblast transition and androgenetic alopecia, suggesting AMT may play a role in fibrosis associated with the condition but presents no new results.

This case study speculates on a potential link between angiosarcoma and hair follicle miniaturization-induced alopecia in an elderly woman, suggesting possible directions for new treatment research.

This study observed that pigmented casts are present in various alopecia types but are not specific to any single diagnosis, with distinct morphological features noted in trichotillomania.

This article is a letter to the editor about fibrosing alopecia in a pattern distribution and reports no new research findings.

This article describes a woman's case of slowly progressive nonscarring alopecia with unique biopsy findings, suggesting the need to reexamine similar cases currently classified as chronic diffuse alopecia areata.

This case report describes alopecia universalis-like hair loss occurring in two patients with cutaneous T cell lymphoma, providing clinical, dermoscopic, and pathologic features to help differentiate it from alopecia areata universalis.

This study describes permanent scalp alopecia in patients receiving chemotherapy, radiation, or both, and highlights the need for further research to identify causative factors and mitigation strategies.

This article reviews androgenetic alopecia and its underlying mechanisms, highlighting genetic and androgen factors in its onset, and does not report new research results.

This review discusses the natural progression of androgenetic alopecia and potential factors influencing its long-term prognosis, reporting no new clinical results.

This study found that hair loss in an Olmsted syndrome mouse model with a Trpv3 mutation was linked to premature keratinocyte maturation, affecting hair follicle structure and function.

This review discusses the histological features and diagnostic challenges of alopecia areata and emphasizes the need for genetic research to develop future therapeutics; it reports no new clinical findings.

This study found that topical formononetin treatment promoted hair regrowth in mice by normalizing hair follicle size and inhibiting apoptosis-related pathways.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This article discusses inflammatory perifollicular fibrosis and alopecia but provides no new research findings.

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

Some men can have female pattern baldness without hormonal abnormalities or signs of feminization.

This paper discusses androgenetic alopecia, its causes, synonyms, and patterns, but reports no new findings or clinical results.

This case report describes a 22-year-old woman who developed persistent, non-scarring hair loss and premature ovarian failure following a myeloablative umbilical cord transplant for acute myeloid leukemia.

This article reviews the foundational tenets of hair restoration and emphasizes the importance of adapting techniques for different ethnic populations, but reports no new clinical results.
