In this case report, a nearly 12-year-old boy with alopecia universalis and atopic dermatitis experienced full hair regrowth and improved dermatitis following treatment with upadacitinib, a JAK 1 inhibitor, showing notable positive effects on his psychological well-being and family.

This paper introduces an algorithm for using smart device-mounted microscopes to analyze scalp images and diagnose hair loss by extracting specific hair loss features.

This review covers the epidemiology, risk factors, and diagnosis of alopecia, highlighting existing treatments like finasteride and minoxidil but focusing on new strategies without providing clinical results.

In this study, researchers found that alopecia areata patients show a significant reduction in suppressive regulatory T-cells and an increase in inflammatory T-cell populations, suggesting an immunological imbalance contributing to the disease.

This study found that feeding mice high levels of dietary vitamin A increased WNT signaling, which activated hair follicle stem cells and may have accelerated alopecia areata progression.

This study reports that CD200R expression is significantly reduced in an experimental mouse model of scarring alopecia, suggesting a potential role for this pathway in immune regulation and hair follicle protection.

A man's skin cancer improved and some of his hair grew back after treatment with a special light therapy and a medication.

This review examines the interplay of genetics and neuroimmunology in alopecia areata, highlighting its potential to inform broader autoimmunity research, but reports no new findings.

This review discusses the diagnostic and therapeutic approaches to furunculosis, emphasizing the importance of hygiene and microbiological testing to prevent and manage recurrent infections, and reports no new clinical results.

This review discusses the mechanisms behind alopecia areata and primary cicatricial alopecia and reports no new clinical results, aiming to guide the development of targeted treatments.

This case report discusses a successful treatment of Alopecia Areata with tofacitinib and includes a literature review on the condition's pathophysiology and the mechanism of JAK inhibitors, though it notes the high failure rate of available treatments and absence of FDA-approved options.

This study observed that expanding regulatory T cells in the skin of mice with alopecia areata did not reverse the condition, indicating that additional immunotherapy may be necessary.

This review discusses the genetics, therapy, and prognosis of childhood alopecia areata, noting that while current treatments are not curative, new modalities may improve future outcomes; it reports no new clinical results.

This review provides an overview of genetics, causes, and treatment options for alopecia areata but reports no new clinical results and emphasizes the importance of support for those affected.

In this study, researchers explored the immunological mechanisms involved in alopecia areata and suggested that targeting immune responses, particularly using JAK inhibitors and other immunomodulatory drugs, could help achieve stable remission and improve patients' quality of life.

This study suggests that the attachment and interaction between dermal papillae and the hair bulb matrix are crucial for normal hair follicle growth and development in vitro.

Androgenetic alopecia may be irreversible due to the detachment of a muscle from hair follicles.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.

This review discusses the pathogenesis of alopecia areata, highlighting the role of immune privilege collapse in hair follicles but reports no clinical results.

This review explores the autoimmune hypothesis of alopecia areata and the possible genetic and melanogenesis-associated autoantigens, but reports no new clinical findings.

This study found that alopecia areata is linked to genetic factors, specifically HLA haplotypes on chromosome 6, and involves immune privilege collapse at hair follicles which is mediated by the JAK-STAT pathway and pro-inflammatory cytokines like IFN-γ.

This review discusses the association between emotional stress-related neuropeptides and the pathogenesis of alopecia areata, reporting no new experimental findings.

This review discusses the complex interplay of factors controlling hair regeneration and highlights the potential for targeted clinical applications in various hair disorders, while reporting no new clinical results.

This abstract provides background information on alopecia areata, describing it as an autoimmune condition leading to non-scarring, patchy hair loss but does not report specific study results.

This case report describes a 22-month-old with alopecia universalis who showed improved hair growth after receiving combination therapy with minoxidil, corticosteroids, and excimer laser.

This study utilized targeted genomic sequencing and whole exome sequencing to identify novel common and rare genetic variants in Alopecia Areata, revealing potential mechanisms contributing to disease susceptibility.

This chapter reviews therapies for skin and corneal regeneration and hair loss, discussing various treatments but presenting no new research findings.

This research reported that the FDA approved Litfulo® (ritlecitinib) as the first oral treatment for severe alopecia areata in adolescents over 12 years old, with 23% of treated patients showing significant hair regrowth in clinical trials compared to 1.6% with placebo.

This review discusses the potential association between vaccination and alopecia areata, highlighted in case reports, notably with the hepatitis B virus vaccine, but provides no new results.

This study examined the formation of acquired curved hair and found that the fusion of hair matrix cells during follicle regeneration contributes to asymmetric follicle shapes and curved hair, potentially linked to changes in type IV collagen and protein expression levels.
