This review outlines the evolution of hair follicle engineering and its foundational discoveries, but reports no new experimental results.

The authors concluded that trichoscopic examination can be useful for diagnosing syphilitic alopecia in patients with idiopathic alopecia, though the findings are nonspecific and further studies are needed.

In this study, a 38-year-old male with syphilis-related mixed pattern alopecia showed marked hair regrowth and resolution of postauricular lymphadenopathy after treatment with benzathine penicillin, suggesting that lymph node and hair examinations, along with trichoscopy, can aid in the diagnosis of alopecia syphilitica.

This study found that trichoscopy is crucial for distinguishing lupus erythematosus-specific alopecia from alopecia areata, leading to more accurate diagnoses and better outcomes for patients.

This report details a case where diffuse lichen planopilaris and female pattern hair loss in a 32-year-old woman mimicked diffuse alopecia areata, highlighting the diagnostic value of dermoscopy-guided biopsies and the importance of timely treatment to prevent disease progression.

This paper identifies challenges in diagnosing alopecia variants, emphasizing the importance of pathologists understanding hair follicle histology, biopsy types, and collaborating with dermatologists to improve diagnostic accuracy.

This article discusses the clinical features and treatment options for common types of hair loss in women and reports no new clinical results.

This case report discusses alopecia syphilitica in a young Belgian man, notes that hair loss was his only symptom, and highlights the improvement following penicillin treatment.

This article previews a Journal of Investigative Dermatology quiz on diagnosing male androgenetic alopecia and offers no new research results.

This article discusses various aspects of hair and scalp health, ancient philosophical perspectives on hair, and causes of hair disorders in children, without reporting new clinical results.

This review discusses the role of dermal sheath cells in hair follicle regeneration, suggesting they show potential for treating pattern hair loss, but emphasizes the need for further human studies.

This article discusses various patterns of hair loss associated with lupus erythematosus, emphasizing the importance of identifying the specific type to aid in classifying systemic lupus erythematosus.

This study found distinct gene expression patterns in the blood of alopecia areata patients, suggesting involvement of immune processes and new pathways like Wnt signaling and apoptosis in disease pathogenesis.

This study is the first to describe a mixed pattern of essential syphilitic alopecia using trichoscopy, identifying features like tapered bended hairs and perifollicular hyperkeratosis in a patient without secondary syphilis symptoms.

This case report describes a 58-year-old man with ophiasis-pattern alopecia areata who showed significant hair regrowth after treatment with clobetasol and microneedling with triamcinolone.

This article discusses the characteristics of alopecia areata, including its reversible hair loss pattern and uncertain causes, but reports no new clinical findings.

This case report describes a novel dermoscopic finding of blue-grey dots in a target pattern around yellow dots and follicles in radiation-induced alopecia following cerebral angiography with fluoroscopy.

This study suggests that ADAM 10 and 12 proteases may play important roles in the regulation of hair cycling through their expression patterns in hair follicle structures.

This study demonstrated the expression of type 1 interferon-related proteins in inflammatory lesions of alopecia areata, showing a distinct distribution pattern compared to cicatricial alopecia.

This review discusses chemotherapy-induced alopecia, highlighting its pathogenesis, clinical patterns, and current therapeutic approaches, with no new clinical results reported.

This case report describes a 26-year-old with systemic lupus erythematosus presenting with psoriatic alopecia, revealing a novel scalp dermoscopic pattern of “patchy dotted vessels.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.

This study revealed gene expression patterns in yak hair follicles during different growth phases, enhancing the understanding of cell fate specialization and providing insights for yak villus development.

This study observed that EZH2 expression scores in the epidermis, dermis, and hair follicles decrease with gestational age in human fetuses, and these scores were significantly higher in adults, indicating that lower EZH2 levels may be required for full skin differentiation and maturation before birth.

This descriptive study observed that a "moth-eaten" pattern of hair loss can occur in several skin diseases, with lichen planopilaris and discoid lupus erythematosus being among the most common conditions identified in patients from Baghdad, emphasizing its potential as a diagnostic tool for clinicians.

This report details two cases of alopecia areata with unusual annular and circinate patterns, highlighting atypical morphology of the condition.

This study found that JAK inhibitors used to treat alopecia areata have varied safety profiles, with different adverse events associated with each drug; tofacitinib and ruxolitinib had earlier onset of events, while baricitinib and ritlecitinib showed distinct delayed patterns.

This article reviews the characteristics, differential diagnosis, and management options for papular acantholytic dyskeratosis of the vulva, illustrated by a case of a 21-year-old patient, but reports no new clinical results.

This article reviews the structural similarities and common disorders of hair and nails, highlighting their joint involvement in congenital and acquired conditions, but it reports no new clinical results.

This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.
