Human hair follicles have their own thyroid hormone system.

This study describes a simplified method for isolating and cultivating human hair follicle papillae that can be easily executed by new lab personnel.

Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.

This study found that a stochastic follicular automaton model replicates hair follicle cycle fluctuations, with deterministic simulations aligning with steady-state levels as follicle numbers increase.

This case report describes the dermoscopic features of two cases of the tumor of the follicular infundibulum, contributing new insights as they had not been previously detailed in the literature.

The authors present a case of punctate follicular porokeratosis, suggesting it as a distinct clinical entity distinguished by keratotic lesions originating specifically from hair follicles.

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

This study found that female pattern hair loss is more common than previously thought among Indian women, with the most frequent pattern being diffuse hair loss over the vertex.

This report describes a rare case of a woman with keratosis follicularis presenting with extensive alopecia and nail abnormalities, adding to the medical literature due to its unusual presentation.

This article discusses the potential for targeted therapies in hair loss by exploring inflammatory and cytokine-mediated processes, but it presents no new clinical results.

This article reviews female pattern hair loss in women, highlighting its characteristics, treatment options, and the need to differentiate it from other hair loss conditions, and reports no new clinical results.

This commentary reviews the evidence for microinflammation's role in pattern hair loss and suggests that further studies with age- and sex-matched controls are needed to substantiate the findings.

This study observed that progressive frontal recession in postmenopausal women may exhibit features of fibrosing alopecia, suggesting a distinct reaction pattern from typical lichen planopilaris.

This study suggests that male androgenetic alopecia and female pattern hair loss follow distinct progression pathways, characterized by different trichoscopic patterns related to hair diameter and follicular unit changes.

In this hospital-based cross-sectional study, researchers found that alopecia is more prevalent in younger patients, with alopecia areata and lichen planopilaris being the most common types among noncicatricial and cicatricial cases, respectively; additionally, thyroid abnormalities were frequently associated with both types of alopecia.

This article discusses the kinetic and topographical heterogeneity in follicular thyroid neoplasms and reports no new research findings; the authors emphasize understanding diverse growth patterns.

This study reports that the prevalence of female pattern hair loss increases with age, affecting 12% of women by age 29, 25% by age 50, and 41% to 50% by age 70 and older, with risk factors including genetics and certain endocrinological conditions.

This study found that dermoscopy showed distinctive patterns for different types of alopecia, supporting its clinical usefulness for diagnosing diseases with small round or oval hairless patches on the scalp.

This case report suggests that tufted hair formation can occur in localized exudative inflammatory scalp lesions, as observed in a Japanese man with pemphigus vulgaris.

This study found that female pattern hair loss is more common in women with thyroid disease and is associated with the duration of the disease, while alopecia areata is not more frequent.

This study found that female pattern hair loss may be influenced by genetic factors and hormonal changes, particularly in young adults, and identified specific dermoscopic features associated with the condition.

This study found that Follicular Maps, derived from trichoscopic images, remained consistent over time and unaffected by hair cycling or noncicatricial alopecia, offering a precise tool for diagnosing and monitoring hair and scalp conditions.

The authors concluded that pattern hair loss is a complex condition with limited treatment efficacy and two FDA-approved drugs, finasteride and minoxidil, to slow its progression.

This study found that sebum excretion is not increased in women with female pattern hair loss, suggesting nonandrogenic factors may contribute to hair loss in some women without hirsutism.

In this study, the researchers found that scalp hair follicles affected by female pattern hair loss are poorly vascularized, likely affecting nutrient delivery, but capable of nutrient uptake when supplemented.

This letter argues that cicatricial pattern hair loss likely represents end-stage androgenetic alopecia and not a variant of lichen planopilaris, as previously suggested.

Early diagnosis and treatment can help manage fibrosing alopecia in older women.

This report describes a 57-year-old woman with fibrosing alopecia in a pattern distribution, who experienced hair regrowth with combined treatment including hydroxychloroquine and other topical and oral therapies.
