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 study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

This case report describes the first observed instance of fibrosing alopecia in a pattern distribution in a child, suggesting the condition is not solely androgen dependent.

This clinical study on fibrosing alopecia in a pattern distribution among a Latin American population reports no new results but addresses this specific condition in its demographic context.

In this study, reduced hair density, diameter, and follicle miniaturization were key characteristics of female pattern hair loss in Southern Chinese women, with occipital and temporal sites also affected.

This correspondence highlights existing research on pattern hair loss, discussing findings about immune deposits, lymphocytic infiltration, and responses to treatment, and calls for future well-controlled studies.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This study found that female pattern hair loss was present in 12.5% of PCOS patients examined, with most cases in younger women, highlighting early detection and management importance.

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

This study found that fibrosing alopecia in a pattern distribution in Hispanic male patients often resembles androgenetic alopecia, with a tendency for earlier onset compared to European and North American populations.

This study confirms that scalp hair follicles in Chilean subjects exhibit seasonal variations, with a higher percentage of follicles in the telogen (resting) phase during the summer compared to the winter.

Ludwig pattern hair loss results from varying androgen sensitivity, causing fewer thick hairs and more thin hairs.

This study analyzed 24 Japanese cases of fibrosing alopecia in a pattern distribution and found a distinctive "parachute" hair loss pattern, emphasizing unique clinical characteristics potentially influenced by racial factors.

In this 10-year study at a single hair referral center, pattern hair loss was the most common type of alopecia, affecting 67% of patients.

This study reported that in men with androgenic alopecia, a distinct subclinical hyperpigmentation pattern was observed in the scalp, associated with baldness severity and possibly linked to local melanin production by pilosebaceous units.

This report presents four new cases of follicular porokeratosis, which exhibit distinct histological features where the cornoid lamella are confined to the follicular ostia.

Human hair follicles have a unique cell distribution and differentiation pattern during growth.

This review details pathologic changes in hair follicles, such as infundibular hyperkeratosis and inflammation, but offers no new diagnostic results.

This case report highlights the importance of trichoscopy in diagnosing fibrosing alopecia in pattern distribution, distinguishing it from female pattern hair loss, and guiding effective treatment.

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

This study found that among women with frontal fibrosing alopecia, 100% showed dermoscopic elements suggestive of the condition, with perifollicular erythema often indicating disease activity.

This study observed that specific trichoscopic features like white peripilar signs, scalp pigmentation, and focal atrichia are associated with advanced female pattern hair loss in Fitzpatrick skin type III patients.

Among patients with biopsy-proven FAPD in specialized hair clinics, this study found the condition is common in females around 52.5 years old, with treatment generally stabilizing or slightly improving hair loss, despite challenges in differentiating FAPD from androgenetic alopecia.

This study suggests that the presence of more than six vellus hairs in the frontal scalp at 20-fold magnification can be an additional criterion for diagnosing early female pattern hair loss.

This study identified clinical features and genetic variants associated with early onset female pattern hair loss, highlighting decreased hair shaft density and specific SNPs related to androgenic features.

In this study, trichoscopy consistently identified typical findings of frontal fibrosing alopecia, revealing three unusual clinical patterns in 18.4% of patients, which may aid in the differential diagnosis when clinical presentations are atypical.

This article is a letter discussing a clinicopathologic study of 90 cases of trichofolliculoma and reports no new results.

The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

Tufted folliculitis is common in patients with folliculitis decalvans.
