This review discusses advancements in understanding hair cycle and inflammatory alopecias, proposing a standard classification and tiered treatment recommendations, but reports no clinical results.

This article reviews common hair loss disorders, emphasizing their potential links to systemic disease and the importance of thorough diagnostic evaluation, but reports no new clinical results.

Most patients with alopecia areata in Syria are young adult males, often with patchy scalp hair loss.

This study found that young adult Ukrainian men with alopecia areata had significantly different skinfold thickness at several body sites compared to healthy peers, suggesting unique patterns of fat distribution associated with the disease.

This review outlines a systematic approach for dermatologists to accurately diagnose hair loss disorders, emphasizing the importance of differentiating between scarring and non-scarring alopecia to guide appropriate treatment decisions.

This chapter details the causes and diagnostic process of pediatric alopecia, including trichoscopic findings, but reports no new clinical results.

This study reported an increase in allergic contact dermatitis cases linked to natural products, particularly propolis and marigold, with a higher incidence in women than men.

Lack of small, fine hair on the front hairline is a key sign of frontal fibrosing alopecia.

This paper reviews alopecia areata incognita, a condition causing diffuse hair loss without typical patches, and highlights the need for scalp biopsy for diagnosis, but reports no new findings.

This study found that patients with alopecia, particularly alopecia areata and female pattern hair loss, often have vitamin D deficiency, suggesting that screening for vitamin D could benefit these patients.

In this study, researchers identified yellow dots as the most common dermoscopic feature of alopecia areata, followed by black dots, broken hairs, short vellus hair, and tapering hairs.

This review highlights the evolution of assessment tools for alopecia areata, revealing newer tools that evaluate beyond scalp hair loss, including psychosocial impact and disease chronicity, which can aid clinicians in developing individualized treatment strategies and enhance research in pediatric dermatology.

This retrospective study described the demographic characteristics, treatments, and prognosis of children with alopecia areata in a clinical setting, reporting a remission rate of 34.5% and highlighting the need for more comprehensive epidemiological data in this population.

This article discusses the use of platelet-rich plasma as a supportive treatment for hair loss, emphasizing its potential to enhance hair follicle health and patient satisfaction, but reports no new clinical results.

This review examines the definition, classification, mechanism, clinical efficacy for hair regrowth, and potential adverse effects of platelet rich plasma, but does not present new experimental results.

Results are not reported in this abstract, which notes that while Janus kinase inhibitors like baricitinib show therapeutic benefits for alopecia areata, the mechanisms and reliable predictors of response remain unclear.

In this study, activation of Tgr5 was found to improve alopecia areata and bone microstructure in mice by down-regulating the JAK1-STAT3 signaling pathway.

This study introduced a non-invasive, three-step diagnostic algorithm for alopecia that combines clinical and trichoscopic features to accurately identify alopecia subtypes, potentially reducing reliance on invasive histopathology.

This review examines the clinical presentation of alopecia areata in children and compares it to adult-onset cases, noting that data on pediatric cases is scarce and often varies, with reported onset typically between ages 6 and 12.

This study found that total serum IgE levels were elevated in patients with alopecia areata compared to controls, suggesting a possible involvement of IgE and Th2 cytokines in its pathogenesis.

In this single-cell transcriptomic study, researchers analyzed AA scalp samples and found distinct immune and nonimmune cell activation patterns, with elevated TH1/TH2 and JAK/STAT markers potentially contributing to hair follicle immune privilege disruption and disease severity.

This research outlines a protocol for a systematic review to map the evidence on alopecia areata in Sub-Saharan Africa, aiming to identify research gaps and guide future studies and policy decisions related to this condition in the region.

In this study, researchers found a significant association between attention-deficit/hyperactivity disorder stimulant medications and alopecia universalis in children, although this finding was based on a small sample size.

This review discusses regenerative medicine approaches for treating alopecia, including mesenchymal stem cell therapies and platelet-rich plasma, but reports no new clinical results, emphasizing the need for further study.

Korean medical treatments are effective for alopecia areata, especially in less severe cases.

This study observed that alopecia areata in children often presents as mild scalp patches, with the majority showing some hair regrowth following treatment, particularly when using potent topical steroids, which were most commonly prescribed in the reviewed cases.

This review explores low-level light therapy's potential as a noninvasive treatment for various forms of alopecia, noting its promising results in hair regrowth and density but highlighting the need for standardized protocols and further research.

This review addresses the causes, mechanisms, and treatment options for the most common non-scarring alopecias in females, including telogen effluvium, alopecia areata, and female pattern hair loss.

In this descriptive hospital-based study, researchers found that telogen effluvium was the most common cause of hair loss among women aged 20 to 40, with most cases occurring over 6 weeks to 6 months without an associated illness.

This article discusses the role of regulatory T cells in alopecia areata, where their deficiency in hair follicles may lead to impaired local immunity and suggests potential therapies like CAR-T reg cells and low-dose IL-2 to alleviate autoimmunity and promote hair regeneration in affected individuals.
