This study systematically reviewed androgenetic alopecia's clinical features, mechanisms, and treatments, highlighting that current drugs have limitations but emerging therapies and personalized treatment strategies could enhance efficacy and outcomes.

This case report highlights that scarring alopecia with features of dystrophic epidermolysis bullosa and lichen planopilaris can occur in patients with a COL7A1 mutation, emphasizing the need to recognize concurrent inflammatory causes.

This case report describes a novel instance of scarring alopecia with features of frontal fibrosing alopecia in a patient with systemic sclerosis, suggesting a potential link between the two conditions not previously reported.

This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

This review discusses the role of epithelial–mesenchymal transition in cutaneous fibrotic disorders and highlights potential molecular targets for therapy, but reports no new clinical results.

In this study, key histologic features such as mucinous perifollicular fibroplasia were identified to aid in the diagnosis of lichen planopilaris.

In this study, certain trichoscopic features were found to be sensitive and specific for diagnosing primary cicatricial alopecias and its subtypes using dermatoscopy.

This study found that adipocytes in the interfacial white adipose tissue adjacent to fibrotic lesions in systemic sclerosis show unique phenotypes and contribute to the condition's pathogenesis.

This study suggests that dermal adipocytes might play a key role in skin aging due to their transformation into fibrotic structures in chronically photo-damaged skin.

This study reported that alopecic lesions after radiation exposure during angioembolization share dermoscopic features with alopecia areata, highlighting the importance of accurate patient history to avoid misdiagnosis.

In this study, HPH-15, a newly synthesized compound, demonstrated potential in reducing skin fibrosis in a mouse model by targeting underlying pathogenic mechanisms and exhibited a good safety profile, warranting further clinical trials for fibrotic skin disorders like systemic sclerosis.

This study reviewed scalp biopsies from African-American patients, identifying distinct features and diagnostic clues for scarring alopecia types such as traction alopecia and central centrifugal cicatricial alopecia.

This study found that in Alopecia Areata, increased non-anagen terminal follicles and peribulbar lymphocytic infiltrate are consistent histological features, even in cases that have progressed to scarring.

This article reviews trichoscopic techniques for diagnosing common hair loss conditions and presents a revised algorithm for identifying specific features of cicatricial and noncicatricial alopecia, but reports no new clinical results.

This study established a murine model for radiation-induced skin reactions, replicating clinical and histological features to aid future mechanistic and therapeutic research.

This chapter reviews various mucocutaneous manifestations of endocrine disorders and provides illustrative images of these clinical features, but reports no new research findings.

This study describes a newly observed "inflammatory vellus involvement" pattern in early frontal fibrosing alopecia, which may lead to misdiagnosis due to the absence of typical histological features.

This review systematically analyzed literature to differentiate desmoplastic trichoepitheliomas from other cutaneous tumors based on clinical, histopathological, and immunohistochemical features but reports no new clinical results.

This study found that lichen planopilaris was the most common variant of cicatricial alopecia among patients, with perifollicular fibrosis being a prevalent histopathological feature.

In this observational retrospective study, UVF-dermoscopy was found to be more effective than polarized dermoscopy in identifying follicular features and distinguishing between scarring and nonscarring alopecias, particularly in individuals with lighter skin tones.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.

This review discusses primary cicatricial alopecias, detailing their classification, pathogenesis, clinical features, histopathologic findings, and treatment, without reporting new experimental results.

This review outlines the transition from simple hair follicle organoids to immune-competent microphysiological systems, addressing limitations in replicating native hair follicle immune features and discussing their applications in disease modeling and regenerative medicine.

This study synthesizes knowledge of how dendritic cell signals, epithelial integrins, and fibroblast activity converge on TGF-β1 to maintain or disrupt skin healing, contrasting normal and fibrotic scar formation and suggesting possible integrin and immune-targeted treatments for skin fibrosis.

This study examined the molecular communication in psoriasis cells, highlighting unique immune cell interactions and identifying new features of the hair follicle cell-psoriasis axis. It suggests the potential for targeted therapies at the single-cell level to improve psoriasis treatment.

This review summarizes trichoscopic features for diagnosing common hair loss disorders and reports no new clinical results, emphasizing their diagnostic utility in conditions like alopecia areata and trichotillomania.

This review examines the clinicopathologic features of perifollicular elastolysis and indicates that, while its presentation is consistent, there is a lack of high-certainty evidence for effective treatments.

This article reviews confocal microscopy findings in trichoepithelioma and desmoplastic trichoepithelioma, noting similarities with histological features, but it provides no new clinical results.

This study found that trichoscopy can differentiate between dermatomyositis, systemic lupus erythematosus, and systemic sclerosis by identifying distinctive features and may help assess disease activity.

This review discusses the clinical and trichoscopic features of lichen planopilaris and notes its potential underdiagnosis prior to hair transplant, but it reports no new findings.
