This study examined 15 female patients with hypothyroidism to investigate the characterization of their alopecia and ruled out other causes, using medical histories, and clinical, trichoscopic, and histologic findings.

Finasteride may help treat frontal fibrosing alopecia, but more research is needed.

This article explores whether it's possible to stop the progression of male androgenetic alopecia without using antiandrogenic drugs and reports no new clinical findings.

This commentary reviews clinical trials on platelet-rich plasma treatments for androgenetic alopecia and emphasizes the need for standardized preparation methods and concentrations; it reports no new clinical results.

In this small, non-randomized study, researchers reported that injecting hair-follicle-derived stem cells into the scalps of androgenetic alopecia patients improved hair density and caliber compared to a control group, suggesting potential efficacy of this approach; however, larger, randomized studies are needed to confirm these findings.

The document explains hair growth, hair loss types, and other hair-related terms.

This chapter provides a comprehensive review of androgenetic alopecia, covering its key physiological mechanisms, diagnostic methods, and a variety of treatment options ranging from topical therapies to aesthetic and regenerative procedures, emphasizing recent advances observed in dermatological practice.

This study identified a unique transcriptional signature in occipital hair follicles that may protect them from miniaturization in androgenetic alopecia, using an animal-free model to investigate gene roles.

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 study reported that fibrosing alopecia in a pattern distribution can occur in patients of color, with clinical and histopathological features allowing for an accurate differential diagnosis.

This study identified acute localized telogen effluvium as a potential cause of temporal hair loss following rhytidectomy.

This study found that in male androgenetic alopecia, the contrast enhanced phototrichogram technique was superior in detecting changes in hair density and thickness compared to other methods.

In this study, detailed examinations of alopecic lesions in two female Cronkhite-Canada syndrome patients suggested hair regrowth might occur without systemic corticosteroids if not required for gastrointestinal treatment, and hair loss may begin with anagen-telogen transition.

This study observed phenotypic diversity in hair loss among Japanese individuals homozygous for the LIPH c.736T>A mutation and suggests that differences in hair thickness may contribute to varying severities.

This source reviews mechanisms and existing treatments for hair aging, highlighting factors like oxidative stress and DNA repair defects that affect hair follicle and stem cell function, and discusses research limitations and future directions in the field.

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 review discusses the evaluation and management of male baldness and related conditions, but reports no new clinical results.

This article discusses various treatments for androgenetic alopecia and reports no new clinical results, noting the condition's aesthetic and psychological impact.

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 study found that traction alopecia risk was higher in adults than children and increased further when traction was combined with chemically relaxed hair.

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

This review reports no new clinical results but discusses fibrosing alopecia in a pattern distribution as a distinct scarring alopecia with characteristics of both androgenetic alopecia and lichen planopilaris.

This review evaluates dihydrotestosterone's role in androgenic alopecia and proposes a model suggesting that chronic scalp tension and inflammation contribute to hair follicle miniaturization, identifying fibrosis, calcification, and tension as treatment targets.

This study found that horizontal sections of scalp biopsies in patients with Central Centrifugal Cicatricial Alopecia often reveal follicular miniaturization, inflammation, and scarring, which can guide personalized treatment.

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 review discusses the histologic features of nonscarring alopecia and highlights the importance of clinical-pathological correlation for accurate diagnosis, but reports no new clinical results.

This study found that dermoscopy is an effective tool for diagnosing and monitoring androgenetic alopecia in women, as it helped identify common signs such as hair miniaturization and peripilar brown halo.

Laser hair removal might also work by damaging blood vessels around hair follicles.

This study found that clinically non-affected perilesional scalp in Japanese alopecia patients often showed microscopic abnormalities, which may help in assessing the spread of disease activities.

This study suggests that low proliferation rates in bald areas of androgenetic alopecia patients, along with persistent inflammatory infiltrate, may lead to follicular miniaturization and fibrosis.
